Medical marijuana laws don’t trigger an increase in teen pot smoking, a new study concludes. Some opponents of medical marijuana have said that legalizing the medicinal use of marijuana could send a message to young people that smoking pot is no big deal, ultimately encouraging them to experiment with marijuana and harder drugs.
Pot smoking by teens has been increasing, and earlier research has shown that fewer of them see marijuana as risky. But the new study suggests that medical marijuana laws are not the reason. The research showed no significant increase in 21 states with medical marijuana laws.
