I think I'm getting addicted and things may start going downhill
Why do you think you are addicted in the first place?
Because I have a massive urge to smoke marijuana all the time.
Admitting something is the first step in getting better with it. Right away you need to take responsible action to quit cold turkey or join a dug addiction self help group. Your life will be full of turmoil if not.
I don't care, it feels so good!
How do you think you'll feel 30 years from now when all you've accomplished is staying high all the time? How do you think you'll feel about retirement and facing old age?
