Personally I’ve found I can’t just use weed (or alcohol) in moderation, I just basically pick back up where I left off.

Currently I’m in my 4th bout of sobriety from alcohol and my 3rd from weed. My sobriety from alcohol so far has been the longest bout of my while life at about 6 years and weed is currently at about 9 years.

For some people quitting and then using in moderation is possible, for some it’s impossible. For some it also depends on the drug as well.
