Ever heard of weaning? Its when a baby doesnt stop breast milk at a certain age. Keza the mom decreases his intake slowly, one dose at a time and replaces it with another source of food. The same applies here, one less cigarette every week and you'll slowly get there. But itll be a really tough road cause withdrawal ynorewal and stuff. Try to occupy ur mind with healthy habits like socializing and exercising. Avoid places u used to smoke at or people u do it with. I hope it works out for u ❤️
