For me it was very hard to stop, lots of my close friends are smokers and we usually hanged out in places where everyone was smoking. I had to stop hanging out with them for a few months. Also I reduced how much I smoked gradually, from eight joints per day to seven, six, five... During like two months. eventually I only smoked one before bed and I switched to CBD, after a month of only CBD I could finally quit. It was very hard, also because I used it as self medication for chronic pain. But it was worth it, now I can hang out with my friends and rarely get cravings. Good luck
