You're right in saying the mesolimbic dopamine system undergoes a physiological change. That`s where the reward system for the brain takes place. The same physiological change takes place, to some degree, when you eat chocolate or have sex or any other enjoyable activity. However,that doesn`t mean it was caused by THC. It would be more accurate to say a physiological change occurs as your reward. The reports I`ve read say that THC may contribute to an increase in dopamine levels and thus may be related to reinforcing the effects of marijuana. None of them have said conclusively it is addictive.

Angilion, it seems you are purposely missing the point. THC doesn't cause any physiological change in the human body, ergo it is not physiologically addictive. I can`t explain why it doesn`t cause any change and I can`t explain why cocaine or heroin does. I`ve broken it down into the simplest explanation that anyone should understand. No physiological change equals no physiological addiction.. I submit the onus is now on you to explain why you think it is addictive. Of course, I`m assuming you think it is addictive and not just arguing for the sake of arguing. That would just be childish.

I'd really like an answer to the question I actually asked, which wasn`t a request for yet another explanation of the difference between physical and psychological addiction.
"Why is THC not physically addictive?" is not the same as "tell me again that it isn`t because it isn`t."
All these people all over the net saying that it isn`t...and not one of them knows why. Sounds more like faith than reason.

O.K. Angilion, As to your "natural=harmless" argument, I completely agree with you. After all, U.V.rays are natural. Yet in high doses, they're lethal...as is everything in high doses. Studies show that a lethal dose of THC to be smoked would be 1500 lbs. in a 14 minute period. PAR-TY.
Also, when talking about THC,there is addiction then there is habituation...Two totally different things but the meanings do get confused with each other. An addictive subtance is something that, when taken long enough, produces gross phsyiogical changes in the way the body works, so that normal operation of the body is impossible without that substance being injested. And as the substance must, by definition, form a tolerance, higher and higher dosages are needed. Habituation are things you crave but do not create a gross physiological change in the way your body works. By the way,this is not a class room. We`re not being graded here. Let`s dial it down a bit.
