Im all about what helps the pain. I got addictd to pain killers and lost everything when I got put into rehab, so ganja was the obvious choice for severe pain. Im in no way against chemicals......Im against a substance that you can't control. I continue to recieve 60 percocet every week or two, but only because I cant afford good quality bud and SOMETHING has to touch the pain. Now once I get access to medical grade smoke, i will put the painkillers away as well as cigarettes. I also take a mild anti-depressnt because of a bi-polar issue. So I guess the short anwer is yes, some chemicals are ok, and yes, my meds allow me to smoke with them, without any sort of sideeffect......hope that helps!
