I can give you this advice from my own life experience. I smoked pot everyday for 5 years. Pot was number 1 in my life. It's true that a lot of stuff is better high. Here's a question, what made you come on this website and ask for people's help on how to quit if everything is better on it? To quit you have to make a conscience decision that you want to stop! I can tell you it wasn't easy for me. I quit almost 5 years ago. I picked a day and from that day I have never smoked pot again. I had to get rid of every single friend I had so that I couldn't get influenced by them. Pot was my identity in life. When I stoped I went through some of the lowest and hardest points in my life. Looking back all that pain was worth it. I have a steady job, a car, house, dog, I have new Christian friends. If I was smoking pot I know I would have never been in the place I'm at now. How do I know that, I would of probably been spending time with my pothead friends working some dead end job spending all my extra money to buy more pot. I'm not agains non Christian people smoking pot but as a Christian I think God calls us to a higher standard of living.
So to end my little life rant and opinions. How can you quit weed? You have to REALLY ACTUALLY want to quit. You have to do whatever's necessary to put distance from you and pot. You can't quit if you see it everyday or your friends are calling you to smoke up. Get help if you need it. Do you go to a church? Maybe tell a pastor that you want to quit pot and need some support. A good pastor should help getting you in the right direction. Start making some new friends that are a better influence. There's plenty of things to do that are great without being high. And don't expect your life to change over night. It'll take time and maybe there'll be some relapses. The important part is that you pick yourself up again, start over, and look forward again. Don't be to hard on yourself and be willing to forgive. Quitting pot is a challenge but in my opinion (and from my own life experience) it is well worth it to move on from it. Hopefully that helps a bit
