A major fear about legalizing medical marijuana in the US has been that it would make the drug more accessible for young people to use recreationally.

So far that hasn’t been the case, according to a new study published in the journal Lancet Psychiatry.
By examining periodic survey results of teenagers in 8th, 10th and 12th grade in the 48 contiguous states from the Monitoring the Future study, the researchers found that the passage of medical marijuana laws had no significant effect on teenage usage.
