I used to smoke 12 or more big bong hoots (weed) every day and decided it’s too much. Regardless of what some say, weed can become a strong habitual and physical addiction.
The key to quitting: GRADUALLY use less and less until you stop.
I simply took a count of the number of times I was hitting it. And kept a mark on a calendar every month. First rule, no more than 12 any given day. Then next week, bring it down to 11 hits max, then slowly to 10 max/day, etc…
It’s hard when you quit a habit and are faced with that hole of nothing to do instead. It’s like ripping a mask off your face, except half your face gets ripped off while you were pulling it off, because the drug has become such a big part of who you are.
Cold turkey would have never worked. It’s too punishing. And just buried the problem which will resurface later. I knew this before I started. But gradual easing off does work.
