Also, may I get your opinion as to why not as well?
I don't smoke weed because I want to live a clean life. Not one ruled by a plant that kills brain cells and is addictive.
First off, it's not addictive, and it isn't as bad as people make it out to be, well of course depending on the amount used.
Marijuana is addictive. If it wasn't there wouldn't be rehabilitation for it. Either it's addictive, or it ruined the brains of the people going to rehab because they can't stop using it.
Not trying to be a douche, but just to correct you, Marijuana itself is NOT addictive. The high can be addictive depending on the person, but if used in moderation, you have an awfully slim chance of becoming a major pot head.
