Then put it in PILL form, under constant medical supervision and strict presciption renewals, like Demerol, with none of the other potentially harmful ingredients in cannabis smoke.
People are prescribed hundreds of dangerous drugs daily without constant medical supervision. What you propose is not only ludicrous it shows that your prejudices are clouding your judgment and thought processes. People who have psychotic reactions to pot already have that potential and it may be aggravated by smoking it. I would be looking to professional help for that condition instead of trying to stop everybody else from going through what you went through. Psychosis is genetic, possible environmental. Pot can heighten the symptoms but it is not a cause.
