Prevalence of novel psychoactive substances in selected clinical urine specimens submitted for drug monitoring

Journal of Forensic Sciences, EarlyView.
Abstract Novel psychoactive substances (NPS) are compounds emerging as alternatives to more established drugs of abuse. They are constantly changing and being modified, which makes their detection difficult. The study objective was to determine the prevalence of NPS in selected clinical specimens. Deidentified urine specimen remnants were analyzed that

Estimating thresholds for risk of cannabis use disorder using standard delta‐9‐tetrahydrocannabinol (THC) units

Addiction, EarlyView.
Abstract Background and aims Lower risk guidelines for safer levels of cannabis use could help to reduce the health burden posed by cannabis use disorder (CUD). We aimed to estimate risk thresholds for CUD based on delta‐9‐tetrahydrocannabinol (THC) consumption using standard THC units (1 unit = 5 mg THC).

Detecting cannabis use reduction through biochemical verification of urinary cannabinoids: An aggregated analysis of cannabis use disorder treatment trials examining average reductions and individual cut‐points

Addiction, EarlyView.
Abstract Background and aims Currently, there is no data‐driven cannabis reduction metric using biochemical verification, which represents a significant gap in cannabis harm reduction research, treatment and policy. Using aggregated data from 7 cannabis use disorder treatment trials, the aims of this analysis were to 1) determine if decreases in self ...

Varenicline for cannabis use disorder: A randomized controlled trial

Addiction, EarlyView.
Abstract Background and aims Although cannabis use is widespread and prevalence of cannabis use disorder (CUD) is increasing, limited advancements have been made in CUD medication development. The objective of this study was to test the efficacy of varenicline with medical management for reducing cannabis use in treatment‐seeking individuals with CUD ...

Comparative effectiveness, safety and acceptability of pharmacological and psychosocial interventions for the treatment of cannabis use disorder: A network meta‐analysis

Addiction, EarlyView.
Abstract Aim Our primary aim was to conduct a network meta‐analysis (NMA) for the effectiveness, safety and acceptability of all psychosocial interventions and all pharmacotherapies for cannabis use disorder (CUD). Methods We conducted a NMA of studies identified from two completed systematic reviews examining the effectiveness, safety and ...
