answer:I’d take whatever the doctor told me to take as he or she is the one with the diploma. Morphene is class A for a reason, it’s very strong. If the doctor says I need morphene, chances are that weed just wont help me at all, and if i substitute morphene for weed based on my own self diagnosis, i’m going to end up in a world of pain. I’m smoking some weed right now, I know weed, i have a lot of experience with it, from sativa to indica, from light to strong, its no miracle drug or excellent pain killer. Sure, weed may help take away the sick feeling of chemotherapy or the ache of arthritis, but its no substitute for morphene, weed wont even take away the pain of a tooth ache, much less the pain of say surgery or a car accident.
