Because as a medical marijuana patient, I can tell you first hand how it has helped with my condition. I was diagnosed with Crohn's Disease in 2008 after having a foot of my intestine surgically removed. I was prescribed a cancer drug called mercaptopurine, the idea being that due to the autoimmune nature of my condition that this drug would inhibit my immune system thus preventing it from attacking my own body. Mercaptopurine (or M6P as it is also known) is essentially a prescription for mercury poisoning. I was told that it would take a few weeks to start having an effect while it built up in my system. I was also told that I would need to return to the doctor every 6 months to have my blood tested to ensure that it was not doing any damage to my liver and kidneys. Suffice it to say, I never took my medication, instead I took to marijuana which relieves pain, acts as a muscle relaxant and anticonvulsant (for my intestines), acts as a mild and safe immune inhibitor, stimulates my appetite, and otherwise puts me in a good mood. Did I mention I have been healthy and symptom free since I began taking it.
Yeah, marijuana helps. It has medicinal applications as well as recreational ones and we should embrace them all.
I will now step down off my soap box.
