Abstract
Methamphetamine use is increasing in the Australian population. It has a known association with violent and erratic behaviour and with an increased risk of unnatural deaths. To determine whether victims of homicide have significant exposure to methamphetamine 100 randomly selected de-identified homicide cases from 2012 to 2021 were accessed from the Forensic Science SA (FSSA) Pathology Database to determine the type of homicide and whether methamphetamine was detected in the blood. A total of 76 males and 24 females were found (M:F = 3:1). Of these, 30 victims (30%) had methamphetamine detected in blood, consisting of 26 males and 4 females (M:F = 6:1; male age range 18-53 years, average 36.8 years; female age range 28-63 years average 44.8 years). Levels of methamphetamine ranged from 0.02 to 3.3 mg/L with an average of 0.64 mg/L, with the highest numbers of positive cases occurring in victims of gunshot wounds (45.5%), and the lowest in those with lethal blunt force trauma (23.5%). This study has demonstrated that victims of homicide in an Australian population are more likely to have used methamphetamine than members of the general population. The reasons for this remain unclear although involvement in a drug selling environment may be an important determinant.

Abstract
Background: The Academy of Breastfeeding Medicine (ABM) revised the 2015 version of the substance use disorder (SUD) clinical protocol to review the evidence and provide updated literature-based recommendations related to breastfeeding in the setting of substance use and SUD treatments. Key Information: Decisions around breastfeeding are an important aspect of care during the peripartum period, and there are specific benefits and risks for substance-exposed mother-infant dyads. Recommendations: This protocol provides breastfeeding recommendations in the setting of nonprescribed opioid, stimulant, sedative-hypnotic, alcohol, nicotine, and cannabis use, and SUD treatments. Additionally, we offer guidance on the utility of toxicology testing in breastfeeding recommendations. Individual programs and institutions should establish consistent breastfeeding approaches that mitigate bias, facilitate consistency, and empower mothers with SUD. For specific breastfeeding recommendations, given the complexity of breastfeeding in mothers with SUD, individualized care plans should be created in partnership with the patient and multidisciplinary team with appropriate clinical support and follow-up. In general, breastfeeding is recommended among mothers who stop nonprescribed substance use by the time of delivery, and they should continue to receive ongoing postpartum care, such as lactation support and SUD treatment. Overall, enhancing breastfeeding education regarding substance use in pregnancy and lactation is essential to allow for patient-centered guidance.

Abstract
One-punch assaults also known as 'coward punches', are characterised by a single severe blow to the head causing the victim to lose consciousness, resulting in a secondary impact between the head and surrounding environment. Such impacts may result in brain injury leading to fatality or permanent neurological impairment. In a previous publication, there were 90 one punch deaths around Australia between 2000 and 2012, mostly involving young men drinking alcohol at a licensed venue at the weekend. This prompted a surge of public education and awareness campaigns around Australia, in addition to regulatory and legislative changes aimed at curbing social violence. This retrospective descriptive study aimed to examine one punch deaths since 2012 in Australia to determine if there has been a decrease in deaths, and whether the demographics and circumstances of these deaths have changed. A search of the National Coronial Information System was undertaken for all closed coronial cases between 1 January 2012 and 31 December 2018. Additional information was collected from medicolegal reports including toxicology, pathology and coronial findings. There were 80 one punch fatalities in Australia, almost exclusively involving males. The median age was 43.5 (range 18-71) years and there was a decreasing trend in the number of deaths annually. Most fatal assaults occurred in the state of New South Wales (28.8%) followed by Queensland (23.8%), and in metropolitan locations (64.6%) rather than regional areas (35.4%). Alcohol was the most commonly detected drug, found in 47 cases of the 71 cases where toxicology results were available (66%), with a median concentration of 0.14 and 0.19 g/100 mL in antemortem and postmortem samples, respectively (range 0.005-0.32 g/100 mL). Five deaths reported methylamphetamine, with THC detected in 21.1% of cases. Assaults more commonly occurred on a footpath or roadside (41.3%), followed by a home or dwelling (32.5%). 8.8% of assaults occurred inside hotels, bars or other licenced venues. Most transpired on a weekday, which differed from the pre-2012 period when these assaults occurred mainly on the weekend. While some trends are positive, there has been a shift in the victim demographic as well as the typical environment for fatal one punch assaults, highlighting the importance of public health surveillance in providing a current evidence base to inform policy and practice.

J Forensic Sci 2021; 67:257-264.

Abstract
Motor vehicle driver fatalities (≥18 years) from the files at Forensic Science South Australia were reviewed from January 2008 to December 2018 for cases in which either positive blood sample for methamphetamine (MA) or an illegal blood alcohol concentration (BAC) >0.05g/100 ml were found. Three hundred driver deaths were found with MA detected in 28 cases (age range 21-62 years; ave. 37.8 years; M:F 23:5). Hundred and fifteen cases with a BAC > 0.05 g/100 ml were identified (age range 18-67 years; ave 35.7 years; M:F 95:20). No change was found in numbers of MA cases, although alcohol cases showed a significant decline (p < 0.001). Drunk driving-related fatal crashes tended to occur in the evening (5 p.m. to 11 p.m.), while MA-related fatal crashes had a longer peak extending from late evening until late morning (11 p.m. to 8 a.m.). This study has demonstrated that while roadside breath testing, legislative changes, and increased monitoring have resulted in reduced levels of drunk driving, similar safety countermeasures have had negligible effects on MA use in drivers. Continued monitoring of MA use by drivers will, therefore, be necessary to assess the possible effects, or not, of new countermeasures.

Abstract
ANALYSIS of autopsy files at Forensic Science SA was undertaken over a 20-year period (2000-2019) in five representative time periods to determine the average ages for all adults (≥18 years) where methamphetamine was detected. There were 239 cases with statistically significant increased mean ages over the time of the study ranging from 32.6yrs in 2000 to 42.2yrs in 2019 (p < 0.0001). Although methamphetamine use may be considered predominantly a feature of younger individuals this does not appear to be the case. Whether this apparent increase in the age of methamphetamine users was due to natural aging of methamphetamine users, an increase in use of methamphetamine by older individuals, or to an increased capture of older cases due to wider toxicological screening is uncertain. However, the importance of these results is to alert practitioners to the presence of methamphetamine use in older individuals which may predispose to death given the increased incidence of underlying cardiovascular diseases with age. In addition, in clinical settings there exists a cohort of older individuals who may be at risk of exacerbating their heart disease and precipitating cardiac events by using methamphetamine.

Abstract
Methamphetamine (MA) is a highly addictive and illegal psychostimulant drug and is currently one of the most commonly abused illicit drugs in the world. The on-site rapid detection of trace amounts of MA and screening illicit drugs in clandestine laboratories is important for drug enforcement agencies and the forensic community in general. However, detecting methamphetamine in the presence of nicotine and cigarette smoke by ion mobility spectrometry faces difficulty due to the overlapped spectral peaks of methamphetamine and nicotine. In this work, a new method was developed to detect MA using pyridine as a dopant in the presence of nicotine by a homemade ion mobility spectrometry. The reduced mobilities of MA and nicotine were measured under the temperatures of the drift tube from 40 to 120 °C and doping with pyridine. The result shows that the temperature of 100 °C is beneficial to resolve the two substances. The concentration of doped pyridine is optimized to be 18 ppm. In this doped experiment, the reaction rate of nicotine is higher than that of MA by measuring the instrumental responses of MA and nicotine. No matter how high the nicotine content is, the interference of nicotine can be eliminated in the detection of MA doped with pyridine. This method is also successfully applied for the determination of MA and nicotine simultaneously in real saliva samples. The limit of detection of MA was measured to be about 0.5 ng/μL. The promising results in this work provide an effective method for on-site detection of MA.

Abstract
The term 'amphetamine' refers to a class of synthetic drugs which includes methamphetamine. The latter is a globally popular drug of abuse which induces euphoria, affecting cognitive/psychomotor performance and sleep. It also provokes risk taking and violent behaviour. The central effects of methamphetamine are due to the overproduction of neurotransmitters, resulting in high levels of dopamine. In recent years, there have been significant increases in cases of methamphetamine abuse in North and South America, Australia and Asia due to its ready availability and low cost. The following review examines changing trends in methamphetamine use and problems that arise diagnostically in medico-legal cases in determining the significance of post-mortem blood levels, the relationship of these to ante-mortem levels, the possible effects on physical and psychological behaviours and the possible contribution of the drug to a lethal episode.
