Easily. A lot of stoners I know smoke only weed. Most hard drug users don't even mess with pot because it takes too long to get out of your system.

Marijuana is not a gateway drug. This is one of the biggest bullshit propagandistic statements made in the 'war on drugs.' Someone I know smoked a lot of pot for several years and by incidence tried a little bit of meth and smoked it for a couple of months. Not a lot, but enough to mess with his head. When shit got freaky he just quit solid and hasn't messed with it since. Meth isn't as bad as the people you mess with because you smoke it and the lifestyle you live using it. It just wasn't beneficial to him anymore, and he stopped using it. This guy is kinda like that though, when he realized pot wasn't benefiting him anymore he quit.

It's the individual not the drug. The weak will fall.
