All I said was that it alters your brain chemistry and neurotransmission (due to the THC)... and that's proven fact. You concluded that if it did that it must be physical.
I agree as I said that if it does change your brain, it is a physical effect, but that has to have some definition. I have searched google and it is inconclusive as to whether cannabis is addictive. There are plenty of pages that say it isnt and a few that say it is.
Put it this way. If you took a load of test subjects and they all abused heroin, more likely that not after prolonged regular use, they would be physically addicted and would have trouble giving it up.
If you took a load of test subjects and they all abused cannabis, after prolonged regular use I very much doubt many would have trouble giving up. Perhaps some would have problems but not all would, so what is it that causes some people to have problems and some not to ??
Im not here to go round in circles or bother people. Im an engineer and I like to understand the mechanics/nature of things. I dont take what people tell me as fact but want to know the scientific reasoning behind the nature of the addiction. If there is an article explaining how cannabis addiction works on the brain then I will accept it, not because someone tells me it is so.
