Addiction as a Coping Response: Hyperkatifeia, Deaths of Despair, and COVID-19

Moral injury and cannabis use disorder among Israeli combat veterans: The role of depression and perceived social support

INTRODUCTION

Cannabis use is highly common among military combat veterans, who are also inclined toward developing Cannabis Use Disorder (CUD). The present study examined the association between Moral Injury (MI), which may occur following combat-related acts that violate one's deep moral beliefs, and CUD, as well as the mediating role of depression and the moderating role of perceived social support.

METHODS

Participants were 215 Israel Defense Forces male combat veterans discharged from military service within the past five years, who reported using cannabis regularly (≥3 days weekly) during the past six months. Participants completed a set of validated self-report questionnaires assessing MI, CUD, depression and perceived social support.

RESULTS

Results indicated that MI-perpetration by self and MI-betrayal were positively associated with CUD. Additionally, serial mediation analyses indicated that the associations between MI-self and betrayal and CUD were mediated by depression (direct effect: β = 0.13, p = 0.1, and β = 0.20, p = .04, respectively). Furthermore, moderation analyses indicated that the association between MI and CUD was significant only among participants with average or high levels of perceived social support (for support by a significant other: b = 0.13, p = .006 and b = 0.22, p < .001 for MI-self and betrayal, respectively; for support by family: b = 0.13, p = .009 for MI-betrayal; and for support by friends: b = 0.1, p = .044 for MI-self).

CONCLUSIONS

MI and its association with CUD should be addressed in clinical settings when working with combat veterans.

Addiction in the time of COVID-19: Longitudinal course of substance use, psychological distress, and loneliness among a transnational Tyrolean sample with substance use disorders

INTRODUCTION

Next to an increased use of alcohol, the current pandemic has been associated with increased psychological distress among the general population. Research on its effects on individuals suffering from substance use disorders (SUD) is scarce. This study aimed at expanding the existing literature on this topic with a focus on the impact of loneliness and perceived social support.

METHODS

Sixty-eight people diagnosed with SUD according to ICD-10 from the Austrian state of Tyrol and from the Italian Province of South Tyrol who had been treated in a psychiatric hospital in 2019 and one hundred and thirty-six matched reference subjects of the same regional background participated in an online survey. Sociodemographic variables and scores on the Brief Symptom Checklist, the Three-Item Loneliness Scale, and the Multidimensional Scale of Perceived Social Support were collected at baseline and 5 months thereafter. Baseline took place after the first wave, while follow-up largely coincided with the second wave of the pandemic.

RESULTS

Among both patients and the matched reference group, substance use as a means to feel better facing the pandemic rose and predicted higher levels of psychological distress. Patients were less likely to receive specific care at follow-up than at baseline and presented with a significantly higher prevalence of clinically relevant psychological distress and loneliness than the matched reference group at both assessment times. Among both groups, psychological burden remained unchanged over time. Perceived social support was generally significantly higher in the matched reference group than in patients. Loneliness and, to a lesser degree, low perceived social support predicted psychological distress.

CONCLUSION

These findings emphasize the need of preventive and educational measures regarding substance use behavior for both individuals suffering from SUD and those without mental health disorders.

Peripherally administered cannabinoid receptor 2 (CB2R) agonists lose anti-allodynic effects in TRPV1 knockout mice, while intrathecal administration leads to anti-allodynia and reduced GFAP, CCL2 and TRPV1 expression in the dorsal spinal cord and DRG

The transient receptor potential (TRP) superfamily of cation channels, of which the TRP vanilloid type 1 (TRPV1) receptor plays a critical role in inflammatory and neuropathic pain, is expressed on nociceptors and spinal cord dorsal horn neurons. TRPV1 is also expressed on spinal astrocytes and dorsal root ganglia (DRG) satellite cells. Agonists of the cannabinoid type 2 receptor (CB2R) suppress allodynia, with some that can bind TRPV1. The neuroimmune C-C class chemokine-2 (CCL2) expressed on injured DRG nociceptor cell bodies, Schwann cells and spinal astrocytes, stimulates immune cell accumulation in DRG and spinal cord, a known critical element in chronic allodynia. The current report examined whether two CB2R agonists, AM1710 and AM1241, previously shown to reverse light touch mechanical allodynia in rodent models of sciatic neuropathy, require TRPV1 activation that leads to receptor insensitivity resulting in reversal of allodynia. Global TRPV1 knockout (KO) mice with sciatic neuropathy given intrathecal or intraperitoneal AM1710 were examined for anti-allodynia followed by immunofluorescent microscopy analysis of lumbar spinal cord and DRG of astrocyte and CCL2 markers. Additionally, immunofluorescent analysis following intrathecal AM1710 and AM1241 in rat was performed. Data reveal that intrathecal AM1710 resulted in mouse anti-allodynia, reduced spinal astrocyte activation and CCL2 expression independent of TRPV1 gene deletion. Conversely, peripheral AM1710 in TRPV1-KO mice failed to reverse allodynia. In rat, intrathecal AM1710 and AM1241 reduced spinal and DRG TRPV1 expression, with CCL2-astrocyte and -microglial co-expression. These data support that CB2R agonists can impact spinal and DRG TRPV1 expression critical for anti-allodynia.

The difference between inpatient and outpatient programs regarding trait -anxiety, social support and state-anxiety in during the covid-19 pandemic in Israel

Purpose

COVID-19 pandemic is affecting the well-being and the psychological resilience of different populations, particularly in the addiction field. This study aims to assess anxiety and its severity among patients and staff from different types of addiction services in Israel during this emergency.

Design/methodology/approach

The study was conducted during the period from March–July 2020. Participants included patients and staff (N = 282) from three different types of addiction services, were administered the State-Trait Anxiety Inventory, the multi-dimensional scale of perceived social support and demographic variables. In addition, a logistic regression model was applied to identify predictors of state anxiety by using statistical package for the social sciences software.

Findings

The results show that therapeutic communities clients reported more social support compared to other subjects. State anxiety has a positive strong correlation with trait anxiety both among patients and staff, and it was found as a crucial predictor of state anxiety in the regression equation. There is no statistically significant correlation between state anxiety and social support, gender or education among clients and staff as one. The state anxiety remains relatively stable and characterizes most people, staff and patients, men and women, medical staff members and other professionals.

Research limitations/implications

The current study has some contributions to the addiction field by understanding the psychological distress of a vulnerable population: substance users in treatment settings. The study population relied on convenient samples and future studies should be planned using a cross-sectional design and should take into account substance use measures. The findings are reinforcing the assumption that state anxiety was likely to increase during the coronavirus pandemic.

Practical implications

Adequate services should be planned to avoid relapse or mental deterioration of people who use drugs during health emergencies.

Originality/value

The research points out the unique and real difficulties of SUD clients, as well as the complexity and risks in their staff members’ works. The authors also saw that staff members need attention and maintenance; they are in the front line.

Metaphoric Perceptions of Covid-19 Patients Related to the Disease

This study aimed to explore metaphoric perceptions of patients with COVID-19 including treatment process, family relationships, and mental health via using metaphors. Purposive sampling was used to include participants. Totally 46 patients diagnosed with COVID-19 were included in the study. The metaphor-based data collection process was carried out with three open-ended questions. The metaphors compiled according to questions and grouped by 13 themes according to analysis. Patients explained to COVID-19 process by using 91 different metaphors. Most frequently used metaphors by patients; black hole/dark for the treatment process of COVID-19, steel for family relationships, sea metaphor for mental health. This study, it was determined that individuals are afraid of death, have a serious perception of uncertainty, and their family relationships and this process negatively affected their family relationships and mental states. Nurses have important responsibilities to increase the quality of patient care.

Changes in Alcohol Use during the COVID-19 Pandemic among Young Adults: The Prospective Effect of Anxiety and Depression

Health measures instantiated to reduce the spread of COVID-19 have imposed significant constraints for the population and impacted on drinking habits and mental health. This study longitudinally compared changes in alcohol consumption before and after the COVID-19 outbreak and the impact of sociodemographic and mental health variables on such changes among a community sample of young adults. Data were collected in the context of a larger, ongoing longitudinal study. The sample consisted of 305 young adults from Spain aged between 18 and 26 years (mean age = 21.27, (SD = 2.21), female = 53.4%; college students = 61.6%) who completed first (November-2019 and February-2020; i.e., before the outbreak of COVID-19) and second follow-up questionnaires (March 2021, a year after the COVID-19 outbreak). Alcohol use (quantity and drinking frequency), depression and anxiety symptoms were measured. Quantity and frequency of alcohol use decreased from the pre- to post-COVID-19 period. A decrease in drinking frequency was observed among college students, but not in noncollege peers. Although we found no effect of pre-COVID-19 anxiety on alcohol use changes, those with more depressive symptoms at the pre-COVID assessment were more resistant to decreasing their drinking quantity and frequency after the COVID-19 outbreak. This information will be of value when designing interventions aimed at reducing harmful alcohol use and highlights the role of mental health status when identifying high risk populations of young-adults during this, and future, public health crises.

A Longitudinal Mediation Model of Negative Emotionality, Coping Motives and Drinking Intensity Among Individuals Receiving Community Treatment for Alcohol Use Disorder

AIMS

Negative emotionality is a key domain in frameworks measuring heterogeneity in alcohol use disorder (AUD), such as the Addictions Neuroclinical Assessment (ANA). Recent research has examined the construct validity of the ANA negative emotionality domain, but has not examined whether this domain demonstrates predictive validity for drinking outcomes. In this study, we examined the association between self-reported negative emotionality at baseline and drinking intensity 1 year following AUD treatment initiation. We also assessed whether coping motives for alcohol use at 6 months following treatment initiation and changes in coping motives mediated this association.

METHODS

This was a secondary data analysis of a multisite prospective study of individuals entering AUD treatment (n = 263; 61.6% male; mean age = 33.8). Measures of coping motives and drinking intensity captured those who experienced a lapse to drinking. The associations between the ANA negative emotionality domain, coping motives and drinking intensity over time were assessed using a latent growth curve mediation model.

RESULTS

The ANA negative emotionality domain at baseline was indirectly associated with greater 7-12-month drinking intensity through higher coping motives at 6 months. Negative emotionality was not related to change in coping motives over the assessment period and change in coping motives was not related to 7-12-month drinking intensity.

CONCLUSIONS

This analysis provides evidence for the predictive validity of the ANA negative emotionality domain for coping motives and drinking intensity among treatment seekers who experienced a lapse to drinking. Coping motives may be an important target in AUD treatment among those high in negative emotionality.

Pancreatic Pain-Knowledge Gaps and Research Opportunities in Children and Adults: Summary of a National Institute of Diabetes and Digestive and Kidney Diseases Workshop

ABSTRACT

A workshop was sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases to focus on research gaps and opportunities in pancreatic pain. The event was held on July 21, 2021, and structured into 4 sessions: (1) pathophysiology; (2) biomarkers, mediators, and pharmacology of pain; (3) pain assessment; and (4) pain treatment challenges and opportunities. The current state of knowledge was reviewed; many knowledge gaps and research needs were identified that require further investigation. Common themes included the need to better understand the underlying mechanisms of pain in pancreatic diseases, the relationship of visceral neural pathways and central pain centers, the role of behavioral factors and disorders on the perception of pain, and differences in pain perception and processes in children when compared with adults. In addition, the role of genetic risk factors for pain and the mechanisms and role of placebos in pain treatment were discussed. Methods of pain assessment including quantitative sensory testing were examined, as well as the process of central sensitization of pain. Finally, newer approaches to pain management including cognitive behavioral therapy, nerve stimulation, experimental (nonopioid) drugs, and cannabinoid compounds were covered.

How prescribing available pharmacotherapies for alcohol use disorder can impact the healthcare system: A retrospective quality improvement study

Alcohol use disorder is a multifactorial undertreated chronic disorder influenced by genetic, psychological, and environmental factors. Numerous pharmacotherapies are available and effective but are underutilized in healthcare. The purpose of this retrospective quality improvement study is to determine the impact of education sessions on the availability and efficacy of medications (focusing on Naltrexone) to treat alcohol use disorder in the healthcare system. Control charts were implemented to monitor the system change in two comparable urban areas. Dispensing rates increased at three points after a series of presentations. The first increase from baseline was 2.47 times, the second 3.7, and the third 4.81. Coinciding with these, weekly visits to the emergency department also decreased by 35% and stabilized at a 15% reduction. It was also observed that alcohol use disorder hospital admission rates decreased by 21%, but bounced back once the education sessions ended. Combined with counselling, pharmacotherapies can be effective in combating alcohol use disorder, while potentially reducing demands on the healthcare system.

Parental Reflectiveness, Posttraumatic Symptoms and Alcohol Use Disorder among Israeli Combat-Veteran Fathers

Combat veterans are highly prone to develop Alcohol Use Disorder (AUD) following their release from duty, presumably due to high prevalence of prolonged aversive emotional symptoms such as Posttraumatic Stress Symptoms (PTSS). Parental Reflective Functions (PRF) and Parental Sense of Competence (PSOC) have been identified as key protective factors in predicting maternal functioning and well-being, yet little is known of its role among fathers, let alone combat veteran fathers. In this study we explored whether PRF and PSOC moderated the association between PTSS and AUD among 189 Israel Defense Forces (IDF) male combat veterans. Participants filled out validated measures assessing PTSS, PRF, PSOC and AUD. Results indicated that PTSS, as well as PRF's "interest and curiosity regarding the child's mental states" subscale, were positively correlated to AUD. In addition, PRF's "certainty about child mental states" subscale moderated the association between PTSS and AUD, so that PTSS and AUD were significantly correlated for participants who reported average or high levels of certainty about their child's mental states. This finding may imply that intrusive mentalizing ("hypermentalizing") by veteran fathers may facilitate the association between PTSS and AUD, presumably by constituting a maladaptive mechanism for coping with the stressful uncertainty embedded in the parent-child relationship.

The rise of illicit fentanyls, stimulants and the fourth wave of the opioid overdose crisis

PURPOSE OF REVIEW

This review provides an update on recently published literature on the rise of illicit fentanyls, risks for overdose, combinations with other substances, e.g. stimulants, consequences, and treatment.

RECENT FINDINGS

Overdose due to illicit synthetic opioids (e.g. fentanyl and fentanyl analogs) continues to rise in the US both preceding and during the COVID-19 pandemic. Fentanyl-related overdose is rising in new geographic areas e.g. the western USA. Stimulant-related overdose is also increasing nationwide driven by methamphetamine and cocaine. Polysubstance use, e.g. the use of a stimulant along with an opioid is driving stimulant-related overdose. Other medical consequences of injection drug use are rising including HIV and hepatitis C infections. Medication approaches to treating opioid use disorder remain the standard of care and there are new promising pharmacological approaches to treating methamphetamine use disorder.

SUMMARY

A 'fourth wave' of high mortality involving methamphetamine and cocaine use has been gathering force in the USA. Availability and use of illicit fentanyls are still the major drivers of overdose deaths and the current rise in stimulant-related deaths appears entwined with the ongoing opioid epidemic.

[Consequences of the COVID-19 pandemic for people with schizophrenia, dementia and substance use disorders]

Die COVID-19(„coronavirus disease 2019“)-Pandemie stellt die Sozial- und Gesundheitssysteme weltweit vor unerwartete Herausforderungen. Die direkten und indirekten medizinischen Folgen einer Infektion mit dem neuartigen Coronavirus bringen die Versorgungssysteme vielerorts an die Grenze ihrer Leistungsfähigkeit. Die neurotropen Effekte von COVID-19 können nicht nur neurologische, sondern auch psychische Akut- und Langzeitfolgen nach sich ziehen. Im psychiatrischen Kontext sind zusätzlich die psychischen und psychosozialen Folgen von Kontaktbeschränkungen und Lockdowns sowie die Auswirkungen täglicher medialer Berichterstattung auf Menschen mit psychischen Störungen zu berücksichtigen. In diesem Beitrag werden die Konsequenzen der COVID-19-Pandemie für Menschen mit psychischen Erkrankungen, insbesondere mit Schizophrenie, Demenz und Abhängigkeitserkrankungen, erörtert.

Type D Personality, Stress Level, Life Satisfaction, and Alcohol Dependence in Older Men

Alcohol consumption among older adults is becoming an increasing public health problem due to the rapidly growing elderly population. There is a theory that Type D personality is positively correlated with alcohol dependence. The study aimed to assess the style of coping with stress, emotions and anxiety in elder men addicted to alcohol and the relationship between the above. The study included 170 men aged 60 years and older (mean age - 63 ± 3.1 years) addicted to alcohol staying in the Department of Alcohol Addiction Therapy for Men. They were tested with the questionnaire sheet and the following scales: Perceived Family Wealth (PFW), Family Affluence Scale (FAS), Cantril's Ladder of Life Scale, Satisfaction with Life Scale, Type D Personality Scale-14 (DS14), and the 10-item Perceived Stress Scale (PSS-10). The respondents' wealth on a scale of 1-5 points was assessed on avg. 3.1 ± 0.2. The above was confirmed by the results of the FAS scale study, where the respondents obtained an average of 3.9 ± 1.9 (min. 1, max. 8), which proves their average level of affluence. The evaluation of the satisfaction with life using Cantril's Ladder showed that the respondents were also satisfied with life on average (on average 5.5 ± 1.9). The assessment of life satisfaction using the Satisfaction with Life Scale (SWLS) scale allowed for the conclusion that the respondents were very dissatisfied with their lives (mean 17.2 ± 4.9). The evaluation of the measurement of perceived stress (PSS-10 scale) showed that the respondents obtained an average of 23.5 ± 3.7, and on the sten scale, a mean of 7.7 ± 0.98, which proves a high level of perceived stress. The study using the DS14 scale showed that the respondents were in the negative emotionality (NE) subscale - 17.4 ± 4.5 points, and in the HS scale - 16.2 ± 3.2, which proves that they can be classified as a Type D personality. The participants were very dissatisfied with their lives, with a high perceived stress and Type D personality.

From Enchantment to Disillusion: A Narrative Exploration of Cannabis Use Disorder Among Young Israeli Combat Veterans

Introduction: Substance use is common among military personnel and war veterans, especially combat veterans. Despite substantially high prevalence of cannabis use and Cannabis Use Disorder (CUD) consistently reported among veterans, little is known about psychological factors which may underlie CUD among this population. Methods: In this study, we used narrative analysis in order to interpret retrospective in-depth interviews of combat veterans (N = 12) who were released from mandatory military duty during the past 5 years and currently qualified for a diagnosis of CUD. Participants were recruited from a larger quantitative study were eligible for participation if they screened positive for a diagnosis of CUD according to the Cannabis Use Disorder Identification Test- Revised (CUDIT-R) questionnaire. CUD diagnosis was validated in-person using the cannabis section of the Alcohol Use Disorder and Associated Disabilities Interview Schedule-5 (AUDADIS-5) interview protocol. All interviews were transcribed and coded using the content analysis procedure. Findings: Five main themes were extracted: (a) Traumatic events (b) Attitudes toward cannabis use (c) Combatant identity (d) The role of authority/father figures, and (e) Moral crisis. A meta-theme has been identified, "from enchantment to disillusion," representing a gradual psychological shift from a hopeful, highly motivated stance into the current state of mental rupture and moral injury, which are unsuccessfully compensated by excessive use of cannabis. Conclusions: This study shed light on the etiology of CUD among young combat veterans, highlighting the role of supposed self-medication for trauma and sense of betrayal.

Psychedelic Mushrooms in the USA: Knowledge, Patterns of Use, and Association With Health Outcomes

Introduction: Popular media coverage of psychedelics use, growing research into this class of compounds for psychiatry and decriminalization initiatives, are transforming the public perception of psychedelics. However, little is known about levels of knowledge and psychedelic mushroom (PM) use among American adults. Methods: We examined PM use and various measures of health status, quality of life, and self-reported mental health outcome measures obtained through a national on-line, cross-sectional survey of adults with a demographic composition representative of the US adult population by region, gender, age, and race (weighted N = 251,297,495) from November 2020-March 2021. Results: General mental health and well-being were popular reasons for PM use (63.6%), although use for medically-diagnosed (31.8%) and self-diagnosed (19.0%) conditions was also common. PM users reported more depression and anxiety as reflected in higher GAD-7 and PHQ-9 scores. Factors predictive of PM use included being male [OR 1.54 95%CI 1.09-2.15] and having higher Charlson Comorbidity Index scores [OR 1.42; 95%CI 1.22-1.65]. Self-reported PM use was less likely among participants with health insurance [OR = 0.50 (0.35-0.72)], increased age [OR = 0.92 (0.90-0.93)] and, relative to those living in the west US census region, living in the northeast [OR = 0.27 (0.15-0.50)], midwest [OR = 0.34 (0.20-0.56)], and south [OR = 0.38 (0.26-0.55)]. Discussion and Conclusions: A significant number of Americans are already "self-medicating" with PM and as growing positive media coverage of psychedelics drives public interest in the health benefits of PM, this number will increase. The association between PM use and poor mental health requires further research to inform policy.

Psychedelic Experiences During the Early COVID-19 Pandemic: Findings From an International Online Survey

Introduction: The current corona virus disease (COVID-19) pandemic has caused a serious global health crisis that has affected large parts of the public and private life worldwide, including the use of psychoactive substances. In this study, we investigated the effect of the COVID-19 pandemic on the use of serotonergic psychedelics, i.e., the settings in which people use psychedelics, the motives of usage, and the subjective quality of psychedelic experiences. Methods: The study was part of an international, cross-sectional, internet-based survey (N = 5,049) available in five languages (English, German, Spanish, Italian, and Korean) carried out during the early phase of the pandemic from April to August 2020. Participants were asked to retrospectively rate settings and motives of psychedelic substance use before the pandemic and in the last 4 weeks during the pandemic, as well as changes in psychedelic experiences. Results: Of n = 1,375 participants that reported the use psychedelics in 2019 or 2020, n = 642 (46.6%) also took psychedelics during the pandemic. During the pandemic, participants used psychedelics significantly less often in settings that were outside their home. Top motives to use psychedelics were comparable before and during the pandemic, but participants consumed less out of curiosity, to celebrate, or because friends took it, and more out of boredom. An increase in positively connoted, often pro-social experiences was observed. Two thirds of participants who used psychedelics during the pandemic claimed that psychedelics had helped them to deal better with the corona pandemic at least slightly. Discussion: Changes in setting and motives were mostly in line with restrictions caused by control measures to contain the spread of the virus. The unexpected increase in positively connoted experiences possibly reflects a favorable interaction of environmental macro- and individual micro-contexts during the pandemic (e.g., by reducing the use in more uncontrolled recreational settings or by encouraging a strong self-selection of substance users due to the expectation of "bad trips"). Increased pro-social feelings under psychedelics might reflect a desire for social interactions in times of social distancing and pandemic-related stress and anxiety.

Problematic Use of Alcohol and Online Gaming as Coping Strategies During the COVID-19 Pandemic: A Mini Review

The COVID-19 (coronavirus disease 2019) pandemic has dramatically changed our daily lives and activities, including those originally intended to serve for leisure and pleasure. Drinking and online gaming became coping behaviors used to rescue ourselves from the stress and restricted lifestyle during the COVID-19 pandemic. However, frequent drinking and gaming can result in the pathological consequences of addiction. Those affected use the stimuli not to obtain pleasure, but rather to avoid the displeasure induced by stress and previous use, often unsuccessfully. This review aims to provide an overview of recent longitudinal cohort studies on alcohol and gaming use during the COVID-19 pandemic, as well as to analyze how the pandemic has affected alcohol and gaming use. There was a substantial risk of alcohol and online gaming overuse during the lockdown, which may depend on the pandemic's duration or overuse patterns. Previous studies have shown that increased alcohol consumption and online gaming are associated with heightened stress and anxiety levels caused by social isolation/quarantine. Over time, frequent or excessive alcohol consumption and gaming could lead to an increased risk of more serious mental health problems. Every effort should be made to mitigate mental health problems and ensure adequate adaptation to these exceptional circumstances. Therefore, it would be helpful to encourage physical activity, social interaction, and collaboration to facilitate psychological and physical health.

Availability of Illegal Drugs During the COVID-19 Pandemic in Western Germany

Background: In response to the COVID-19-pandemic, a lockdown was established in the middle of March 2020 by the German Federal Government resulting in drastic reduction of private and professional traveling in and out of Germany with a reduction of social contacts in public areas. Research Questions: We seek evidence on whether the lockdown has led to a reduced availability of illegal drugs and whether subjects with substance-related problems tried to cope with possible drug availability issues by increasingly obtaining drugs via the internet, replacing their preferred illegal drug with novel psychoactive substances, including new synthetic opioids (NSO), and/or by seeking drug treatment. Methods: A questionnaire was anonymously filled in by subjects with substance-related disorders, typically attending low-threshold settings, drug consumption facilities, and inpatient detoxification wards from a range of locations in the Western part of Germany. Participants had to both identify their main drug of abuse and to answer questions regarding its availability, price, quality, and routes of acquisition. Results: Data were obtained from 362 participants. The most frequent main substances of abuse were cannabis (n = 109), heroin (n = 103), and cocaine (n = 75). A minority of participants reported decreased availability (8.4%), increased price (14.4%), or decreased quality (28.3%) of their main drug. About 81% reported no change in their drug consumption due to the COVID-19 pandemic and the lockdown. A shift to the use of novel psychoactive substances including NSO were reported only by single subjects. Only 1-2% of the participants obtained their main drug via the web. Discussion: Present findings may suggest that recent pandemic-related imposed restrictions may have not been able to substantially influence either acquisition or consumption of drugs within the context of polydrug users (including opiates) attending a range of addiction services in Germany.

Alcohol Use and COVID-19: Can we Predict the Impact of the Pandemic on Alcohol Use Based on the Previous Crises in the 21st Century? A Brief Review

The enormous health and economic challenges precipitated by the 2019 coronavirus disease (COVID-19) pandemic are comparable or even greater than those associated with previous historical world crises. Alcohol use, especially drinking to cope with stress, is a concern, as an increase in its sales has been reported in some countries during the quarantine. This study aims to provide a better understanding of what to expect in terms of alcohol consumption, risk factors for excessive use, and its potential consequences during this pandemic based on previous experiences. We investigated how traumatic events related to alcohol consumption. Studies on mass traumatic events (i.e., terrorism as 9/11), epidemic outbreaks (i.e., severe acute respiratory syndrome [SARS] in 2003), economic crises (such as 2008's Great Recession), and COVID-19 were selected. The main keywords used to select the studies were alcohol use, drinking patterns, alcohol use disorders, and alcohol-related consequences. Previous studies reported increases in alcohol use associated with those events mediated, at least partially, by anxiety and depressive symptoms, and posttraumatic stress disorder (PTSD). Being male, young, and single also seems to be associated with a higher vulnerability to develop risky drinking behavior after those tragic events. The discussion of previous risk and protective factors can contribute to elaborate more specific public health policies to mitigate the impact of the current pandemic on people's mental health, especially alcohol-related problems.
