That's funny, I live in Maine and have never got a drug related charge (it would only be for pot). The only ticket I have got is for a rolling stop, and it was before I started smoking weed. I've never stolen from anyone, and I don't feel a strong need to lie about anything.
Interesting fact that you may not know, Coffee Brandy is the leading cause of domestic violence in the state. Allens Coffee Brandy. Find me one case in Maine where marijuana was a catalyst for domestic violence, rather than alcohol.
It's possible that you just know a few very stupid people that use drugs (as far as which drugs, you didn't specify). For example, I'm sure not ALL Tea Party activists are not incredibly stupid... I just haven't been introduced to a tea partier that ISN'T incredibly stupid.
Do you see where I am going with this? There's so much hypocrisy that goes on when people want to legalize something for "medical" use, when the side effects and health risks are equally as low for anyone using the drug. So many problems in this world could be fixed with the legalization of marijuana.
