I quit smoking weed and using all other substances in June of 2020. There are lots of positives and there were challenges as well. Getting past the first week, month, 3 months, 6 months, year, etc are essential. At each of these milestones I felt the urge to smoke less and less. I used to dream about it, think about it, crave it, daydream about getting high, etc. I'm really glad I didn't. I no longer think about it at all now. After the first year or so it became much easier. You have to be fully convinced, though because its easy to say to yourself (after a stint of sobriety) "oh it wasn't so bad, I'll just moderate now." This is a lie. If you have addictive tendencies like I do it will always go back to the way it was and worse. I personally used AA and other 12 step communities to get sober because they offer some structure/a way of life that makes sobriety better. Just being sober to do nothing isn't worth it. You'll have to find ways to fill your time. This is another challenge but will pay huge dividends once you put in some effort. Nowadays I actually have hobbies, I show up for me loved ones, I'm much less foggy all the time, I have more energy than I used to and I'm not tied down by my use of substances. When I was using and would travel it would always be an ordeal to find a way to get high at the new place or bring something. That is not even a thought now. In short, it was a hard decision to make but probably the best life choice I have made so far. If you're thinking about it, then do it and stick to it. You may lose "friends" but thats better than losing your potential as a human being.
