"please drug responsibly" i live to see that slogan. Why not make drug laws simular to the laws about manufacturing homemade alcohol for personal use (person over a certain age can have X amount of a drug in a time frame) and purchase of drugs would be from a dispensary. And to up the amount needed for compensation for tolerance, just have to make an appointment with a doctor for a "dosage physical" and s/he can write a waiver to have added to your "account" so you can purchase a higher dose if the doctor deems it ok. Of course people will stigmatize drug users even when drugs become legal but people who drink (or sometimes those who DON'T drink) are stigmatized. Change is rough, the govt probably doesnt want to go through the hassle.
