An analysis of nationwide study data shows that laws legalizing medical cannabis use are related to increases in illicit cannabis use and cannabis use conditions among adults. The research was funded by the National Institute on Drug Abuse (NIDA) and the National Institute on Alcohol Abuse and Alcoholism (NIAAA), both part of the National Institutes of Health.
Comparing general trends in states with medical cannabis laws to states without these laws, the authors taken a look at information from 3 NIAAA-supported surveys performed in 1991-1992, 2001-2002, and 2012-2013. In addition, the meaning of cannabis use condition was based upon the DSM-IV definition of cannabis abuse or dependence in the previous 12 months. The authors estimate that an additional 1.1 million adult illegal cannabis users and an additional 500,000 grownups with a DSM-IV cannabis disorder might be attributable to medical cannabis law passage. However, detectives also keep in mind there might be other contributing elements.
These findings underscore the significance of taking a look at how more liberal state cannabis laws can increase the threat of cannabis-related health effects. An accompanying commentary on the post by NIDA scientists highlights the possible unfavorable impacts of cannabis on psychological health.
