Then your dad just has that addictive personality. I started smoking weed at 19 (waited for my brain to stop forming) I'm 39 now.....I've never done anything else other than mushrooms and the last time was severalbyears ago. I don't smoke cigarettes, I rarely drink.....I have a good job (actually just got a promotion tuesday) am in shape..... Saying it's a gateway drug is bs. If anything the way they lie about weed causes the 'gateway' problem. Someone tries it and thinks 'this isn't anything like they said! I wonder if they lied about other drugs, too?'
