A Wolf in Sheep's Clothing?

I recently met someone who admitted that he sells weed, among smoking it. However I feel like there probally is more to "just selling weed" due to some of the luxurious items he has a tendency to sport. Is this truly the gateway drug to doing other drugs? I'm conflicted because, outside of this foolishness, this person is highly intelligent, attractive, articulate, and would probally never p as a dealer, but looks are deceiving of course. However, he was bold enough to roll up in front of me, and drive around with it while we were in the car as though I am suppose to be ok with the idea. My better judgement tells me to leave it be beforehand. any suggestions?
