I said this before, for a drug to be physically addictive it has to introduce new receptors in your brain, nicotine and other drugs does this but cannabis does not.

It doesn't have to introduce new receptors into the brain, it just needs to stimulate the release of chemicals that the brain does naturally, so the brain starts to think that it doesn't need to make it's own chemicals, so when you stop, your brain doesn't want to make the chemicals, it just wants you to take the drug.
