Wannabe, I've mixed feelings on it.
I understand it was made illegal in about 1938 by a very bigoted Senator who was trying to target Black Musicians.
At the time, the Medical community had the view that there were benificial uses for the drug but were ignored while legislation passed.
There's no doubt as to the Tax Revenue it could generate by making it a Recreational Drug. (not to mention the financial blow to the drug smugglers)
The Infrastructure for distribution is already in place, Liquor Stores.
You have to consider the potential for abuse. (yes, there are some who would get
totally "Bombed" & get behind the wheel or do other very foolish things)
I think the best bet for "Medical Marijuana" would be in "Pill" form. (D-9 Tetrahydrocanabinol) THC for short.
It could be controlled like any other drug via your Family Doctor & Pharmacy.
The Doctor would know the purity, strenght & dosage amount.
As it stands now in California, the "Doc" gives you a script not knowing the source
of the drug, (is it from a reputable grower who doesn't add harmful chemicals to
stimulate growth?) he doesn't know the strength or dosage amount, just says to you
"Smoke this till it feels good!"
And some people wonder why most of the medical community is opposed...
