It has to be said again and again. While marijuana has no curative value that we know of, it may have the ability to relieve pain for those who are suffering greatly. If so, and if a doctor prescribes it when other prescriptions have failed, then let the patient smoke it by the trainload if they want, and to hell with - and God curse - anyone who decides that the Government knows better.
Maybe implantable slow-release THC sources could be designed for such people: it would be more convenient for them than frequent smoking or eating laced foods, and the control over the distribution would be easier to maintain.
And if "patients" are in "pain" and nothing else works, should they be allowed to grow their own poppy fields and "chase the dragon" every two hours?
I kind of take it as gospel the the government is generally run by fools.
It's just a weed in the garden. It's not evil, in and of itself. It's no different than the argument people make about guns. Guns are not evil, people who use them to commit crimes are. People who use marijuana to kill pain or to relieve glaucoma or to stimulate appetite in wasting syndromes are different than the typical pothead.
