The approval of marijuana for medical use has had little effect on the mental health of the general population in the US. But legalization for therapeutic purposes does benefit those for whom it is intended. This is the conclusion of a study by researchers at the University of Basel.
In the US, access to marijuana has been facilitated in most states since the mid-1990s – whether through medical clearance or through decriminalization of recreational use. However, liberalization is still controversial, and the effects on the well-being of specific groups and the therapeutic value of marijuana remain debated.
While some fear negative consequences from addiction, others highlight the potential medical benefits for people suffering from chronic pain, nausea or convulsions.
In a new study, researchers from Basel have now investigated whether medical cannabis legislation in the USA is improving the situation for sick people and whether it has a negative impact on the mental health of the overall population.
