Just make it a legal produc. The question is how many people would use some RCs or drugs with extreme side effects when they had access to ordinary weed. Also, something like opiates can be unbelievably cheap. There is a reason laudanum was the drug of choice of the poorest segments of society. Its byproduct of the existing poppy harvest and many countries currently have to spend money to get rid of it by washing any poppy seed before selling it. Without having to worry about blowing through a month wage in no time because of the black market cost, the resulting withdrawal and suffering the effects of what ever it was laced with, almost all unwanted side effects would be gone. The question is what do you do with drugs who change the behavior of the user dramatically to the degree that they become a risk to others. We currently have that problem with alcohol and see the side effects in violent and reckless behavior. From domestic violence to drunk driving. The answer might be to shift the approach from restricting possession to restricting consumption and being under the influence in certain areas or situation where they might become a danger to others. The only open question I see is how to deal with expensive, addictive substances that change the behavior of its consumers. Crack comes to mind.
