Abstract

Purpose of Review To summarise empirical research on the adverse and beneficial public health impacts of cannabis legalisation in states in the USA. Recent Findings The most consistent finding from surveys of drug use is that the legalisation of medical cannabis has so far not had an effect on rates of use or cannabis use disorders among youth, but it has increased the frequency of use among adult cannabis users. There are conflicting findings on the impact of legalisation of medical and recreational cannabis use on the following: cannabis use disorders in adults, rates of motor vehicle accidents in which the driver was impaired by cannabis, rates of suicide, and opioid-related harms. The legalisation of recreational cannabis use has increased emergency room attendances for cannabis-related medical condi- tions (acute adverse psychological effects, hyperemesis, and accidental poisoning of children).
