The US government won’t allow clinical trials on marijuana, so research is hard to come by. From what I’ve read about research in Europe marijuana can help with chronic pain, nausea from chemo, and stimulate patients’ appetite. Some people get more anxious, not less, when they light up. Everyone reacts differently. The claims about marijuana curing cancer, glaucoma, diabetes and ingrown toenails are bogus.
I wonder if a study about increased anxiety has been done in states where marijuana is legal and there is no fear of being caught and thrown in jail.
I read that in Holland, marijuana is used in long term care for the elderly facilities. Apparently it has beneficial effects, or else it would certainly be medically prohibited.
