 The fact that cannabis possession carries prison sentences in most developed countries is also pointed out as a problem by European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), as the consequences of a conviction for otherwise law-abiding users arguably is more harmful than any harm from the drug itself.For example, by adversely affecting employment opportunities, impacting civil rights, and straining personal relationships.Some people like Ethan Nadelmann of the Drug Policy Alliance have suggested that organized marijuana legalization would encourage safe use and reveal the factual adverse effects from exposure to this herb's individual chemicals.
