Fine.
My best friend in high school was someone who was well liked, did well in school, and otherwise had a good life. He was smart, and was someone who always had something good to say in our philosophy class. He was a really deep thinker. Some time in our senior year he started smoking pot. Not ever having done it, but only hearing about from our school, I was already wary about it. It alters your mind state. That is FACT. One day, he invited me over to his house to jam, which we did frequently, and so I went over there. He was already high, having smoked before I got there. And I swear to god, the shit he was saying... He turned into the biggest conspiracist when he was high. And the funny thing is, he thought he sounded SO smart. He was saying shit that was really fucking dumb. I can't remember what was said specifically... it was a few years ago, but I remember thinking he was fucking retarded.
ANYWAY
One day we were talking about his pot use, and he mentioned that he had driven high before. I was like, well, doesn't that make you a worse driver? Much like when you're drunk? He said no, that it actually made him more safe because he was 'more aware' of his surroundings. I don't really get it... But regardless, one day he was driving, coming home from some sort of party, and he must have smoked something good, because he blacked out on the road and ran headfirst into a fucking tree. He nearly died. But did that stop him? Fuck no. He was convinced that the drug was safe. And, moreover, he started doing LSD, Cocaine, etc. He finally got clean last year... Or so I hear. I haven't talked to him since high school.
So, please, do NOT tell me it's perfectly safe. Just because YOU have never had a bad experience doesn't mean that it' perfectly fucking safe. It's not. I've seen it firsthand. Harms no one... tell that to him
