You can't argue that you'd be just as good a driver if you were high because it's simply not true.
In my case I'm a better driver after smoking. I drove an obstical course twice (before & after smoking), I had fewer mistakes and a faster time stoned.

As far as weed leading to 'other drugs', the ONLY reason for that is the fact that pot is against the law, which forces you to go to dealers who sell more than just pot.

As long as you don't live 'just' to get stoned, I believe you'll be fine. In other words: use it, don't let it use you.

@THA I was wondering what prompted other "interesting" marijuana conversations with your mom? It maybe that she's not 'ignorant', just concerned and misinformed by goverment propaganda.
