Both dependent and non-dependent cannabis users had exaggerated responses in a brain region that processes reward -- the ventral striatum -- compared with people who didn't use cannabis. Interestingly, the dependent users also had larger responses in a brain region that forms habits -- the dorsal striatum.
Gene Increases Risk for Pot Addiction
Addictive use may rather be driven by changes in brain systems that promote habitual -- automatic -- use, which also may explain the fact that addicts continue use despite a lack of experiencing rewarding effects of the drug. As such, their behavior has become under the control of the drug cues, rather than the actual reward expectation," said lead author Benjamin Becker, PhD.
Dependent users also had increased responses in other regions throughout the brain, including regions that attribute importance to things, for example, drug cues. This suggests that the development of cannabis addiction incorporates additional brain regions that may strengthen a person's desire to seek the drug. Differentiating the unique brain circuits behind dependent cannabis use could also be useful for understanding how to combat the problem of cannabis addiction.

Common symptoms were severe nausea, vomiting, high blood pressure, anxiety, panic attacks and paranoia. Some people argue that because marijuana does not have dramatic withdrawal symptoms like alcohol or heroin, it is not addictive. But there are two errors in this thinking.
Is Marijuana Addictive?
One is that the marijuana of today is more than two times stronger than it was twenty years ago some say much stronger than that , and withdrawing from that is quite a different matter. The other is that it is simply not true: There ARE withdrawal symptoms when a chronic user stops using cannabis. Remember that the above symptoms can be stronger or weaker for the person withdrawing, depending on how much dope he was smoking, over how long, and his own unique physical and mental constitution.
