This all seems a bit silly. There are many pain-killing drugs already available. The attribute of marijuana is the ability to increase a cancer patient’s appetite. A cancer patient dies from starvation and dehydration as the organs shut down one by one. In the earlier stages, any method that serves to increase the patients’ appetite is desirable.
Yes, there are a lot of pain-killers around. And my husband can't take any of them because they tear up his stomach. My daughter is also sensitive to many of them.
Something new, without all the negative side effects of what's already out there, could be wonderful for those that need it.
