I have been smoking 50 years and there isn't a moment I regret. First place marijuana does not kill pain. It relaxes you and helps you deal with it a lot better. It calms you as it makes you hear better taste better feel better and the best part about it it could make you smile. I'm a chronic pain individual who takes Miles opioids because I've given up and everything else as far as trying to dilute my pain. Cannabis is just an additive that makes the whole thing work together and makes life a little easier to deal with our discomfort. When I take a puff and it's just a puff and if you have quality cannabis in a few minutes your taste buds increase, music sounds fabulous, and this best it greates euphoria of calm.
If you live in a state that it's legal go to those people & up for it and they will guide you on what is best and what to choose from for the different types of a feeling that you want to create azerrz different strains for different feelings. It's worth it that's all I can say and best of luck to you.
