I'm sure we could say that alcohol will relieve pain and help you forget about whatever condition you have. Should we prescibe a 12-pack of beer to patients who say that its the only thing that helps them?
No need to, its legal.
Patient will self-presecribe.
But, if it had a legitimate use and there weren't more reasonable alternatives for the patients illness that could treat without the intoxication and harsh effects on the liver, why not?
Marijuana ONLY has this reputation because its a scheduled illegal drug. Its scheduled because at some point in time a politician somewhere saw some political expedience in making it so. I don't smoke weed, and I think its lame, but considering the dangers so many prescription drugs pose to patients I don't see what the harm is in prescribing weed. From a health, behavioral, and public safety standpoint, marijuana is much safer than alcohol, yet its illegal. Makes no sense.
Smoke too much weed you eat a lot, get sketchy, and possibly sleep for extended periods of time.
Take too much Tylenol you liver fails.
I find the entire war on drugs to be ridiculous much like I do the common feelings harbored toward "illegal drugs" which could potentially be used to treat people.
I think a great example is "Testosterone". It was once hailed as wonderdrug! In fact, it use to be farily widely used in the treatment of male depression, with great results and without any major side effects other than HPTA supression (but that's not a problem since the HPTA was probably already shot to begin with since said patient was low on testosterone to begin with! HLD/LDL, blood pressure, etc are unaltered by HRT levels of testosterone).
Well, along come the germans and the russians in the olympics. They kicked our asses because they started doping their athletes with steroids. So, what does the rest of the world do? "ummm....drugs are bad, mkay.". Yep, we flip out because the russians and germans cheated, went all out on a steroids are horrible campaign, demonized them to hell, and made it an unacceptable method of treatment.
Now anytime a doctor mentions the word steroid, little johnny's mommy looks at him like an evil beast and flips out, despite the fact that she has no idea what steroids are, and how they will be used to treat little johnny, and how not all steroids are even remotely the same. She just knows that Lou Dobbs on CNN said that Johnny will turn into a rabid little horndog who is going to eat other children and have sex with the leftovers and then kill himself when he comes off
Only relatively recently has testosterone made it back into the realm of medicine again--and its still not very well accepted. But, those hypogonadic people on HRT are loving it. Helps their energy level, their depression, their sex lifes, etc, etc, etc.
Same goes for Marijuana. Its very popular with cancer patients for a reason
