Hi Pete
The good news is it's possible to quit weed. I smoked it daily for nearly 30 years.
There's two things you need to do tho - the first is to find support, and you'll find plenty of that here.
The second is to make changes in your life. If you smoked to relax yopu're goinna need to find new ways to relax. If you smoked with mates you might have to cut yourself out of the circle for a bit...
It wasn't pleasant giving up weed but it wasn't impossible either - I had a worse time giving up the booze.
If you want to leave weed behind, you definitely can
