Both marijuana and alcohol are illegal for teens to purchase. The question is not which is easier to purchase, but which is more accessible. Alcohol is far more accessible because it is in every grocery store, every convenience stores, plus a high percentage of American homes. It also doesnt have the stigma of being illegal.
Its true that marijuana is the most abused illicit drug, but alcohol is the most abused addictive substance overall.
Legalizing marijuana, as Ive said, will only add to the problem. It will make marijuana more accessible.
