In my opinion I think smoking Marijuana can become a habit that is hard for some to quit. I have seen some use it as a way to help them off some other drugs or to help with depression or whichever it may be. My question is for the ones who say it is hard for them to go a day without smoking are they addicted to the process of smoking marijuana or are they addicted to the relief it gives them. How do you regulate a dosage for a person who would use this to help them with weaning or other phycological issues? I have read that smoking to much can higher the effects of depression so if it were to higher the effect in making them more depressed wouldn't that push them closer to suicidal tendencies? How can we know what each persons right dose is?
