20 Years of Data on Cannabis & Health

Method: A comparison of the epidemiological evidence and conclusions reached in a 1993 literature review with the evidence and interpretation of the same health outcomes in 2013.

Results: Epidemiological research in the past 20 years has clearly shown that driving while cannabis-impaired approximately doubles car crash risk.In summary, the epidemiological and laboratory evidence on the acute effects of cannabis strongly suggests that cannabis users who drive while intoxicated increase their risk of motor vehicle crashes 2-3 times (alcohol increase is 6 1 15 times).

Approximately 1 in 10 regular cannabis users develop a dependence syndrome. Regular cannabis use in adolescence and young adulthood predicts approximately double the risks of: early school leaving and welfare dependence in adulthood, and of cognitive impairment, psychoses, depression and anxiety disorders in adulthood.

Regular cannabis use in adolescence is strongly associated with the use of other illicit drugs (50 fold in better controlled studies).

These associations between regular use and poor outcomes have persisted after controlling for plausible confounding variables in longitudinal studies. This suggests that cannabis use plays a contributory cause in producing these outcomes but some researchers still argue that these relationships are explained by the effects of shared causes or risk factors. Cannabis smoking probably increases cardiovascular disease risk in middle aged adults but its effects on respiratory function and respiratory cancer remain unclear because most cannabis smokers have smoked or still smoke tobacco. More research is needed to understand the effects that increases in the THC content of cannabis products may have had on their adverse health effects.

Animal studies suggested that high doses of cannabis extract caused growth retardation and birth malformations but epidemiological studies did not consistently find an increased risk of birth defects among women who reported using cannabis during pregnancy but it is difficult to interpret the few studies that did reported increased rates of birth defects because cannabis users are more likely to smoke tobacco, and use alcohol and other illicit drugs during pregnancy.

Conclusions: The epidemiological literature in the past 20 years has confirmed that cannabis use increases the risk of accidents, can produce dependence and that there are consistent associations between regular cannabis use and poor psychosocial outcomes and mental health in adulthood that warrant efforts to discourage adolescent cannabis use.
