I read a good quote in a book about cannabis culture:

"Is cannabis addictive? Yes, in the sense that all the incredible things in life are worth endlessly repeating."

Can't remember who said it, sorry . I wouldn't say it's addictive. If I don't have weed, it's not like I pull my hair out in desperation and get ratty at everyone. If I want to get drunk, I will. If I want to get high, I will. Is there any difference?
