Joe Biden: On second thought, I don't think marijuana is a gateway drug

“I don’t think it is a gateway drug,” Biden said on a conference call, according to CBS News. “There’s no evidence I’ve seen to suggest that.”

The former vice president said “some in the medical community” believe marijuana needs to be studied further to determine whether it could lead to other drug use.

Biden’s Monday interview comes weeks after he was widely scolded for telling a Las Vegas town hall crowd that not enough evidence “has been acquired as to whether or not it is a gateway drug.”
