I'm very aware of schizophrenia. but I'm talking about physical withdrawal symptoms, not the side effects of smoking it.

Quitting pot is easier to do than quitting cigarettes because there is little to no physical withdrawal symptoms, because you normally just have a mental dependency on it. Where as cigarettes, alcohol, and a bunch of other drugs can make you sick and can even kill you because your body got rid of the drug and it so used to it that it physically needs it.

Its bad to be addicted to anything, but as for quitting pot is more of a walk in the park than say, quitting alcohol or heroin.
