My grandpa is really sick and in a lot of pain. Is there any serious side-effects that should be considered before using cannabis?
EDIT: it's illegal where I live so I can only get it through a friends dealer, granpa has artritis, a stoma bag, cancer thats untreatable in his abdomen, diabetes type 2, severe skin issues similar too psoriasis aswell as skincancer, nerve pain that is making it hard to sleep and walk his legs hurt all the time, anemia. I might have missed something but thats the worst of it. He was given 3-5 years to live due to the recently diagnosed cancer in his abdomen, he takes morphine several times a day but it doesn't help much.
