Personally i think its all you personality here. Some people have addicting personalites. Im the type of person that if i eat something or do something that ill feeling like doing that for a long period before i get bored with it. Now i know im not addicted to weed (cause i have money to spend, a good dealer, and i havent bought any in weeks), But ill admit to a small crave towards it. Not an addictive crave, just a crave of a good feeling thats all. Can people be addicted...ill say no, but i do believe some people who rely on it for things like depression, or sleep help will feel more of an urge to use it.
