Imagine for a moment if meth were legalized -- production would move beyond shady basements with lax safety measures, distribution would move beyond inner-city gangs and other unpleasant cartels, consumption would move beyond lonely apartments and back-alleys, and storage would move beyond dirty needles and shoddy pipes (it could even be refined into pills).
Now realize that the entire pharmaceuticals industry is born from this desire for safe production, distribution, consumption, and storage of drugs -- and the hypocrisy of selective drug prohibition.
