Instead of addressing the major sicknesses of our society, we grandstand against drugs. Trying to convince anyone who has taken drugs without negative consequences that they are universally bad falls on deaf ears, and rightfully so.
The main problem with drugs is their illegality, not their chemical reactions. Recreational users know their bodies and minds do not rot in a tornado of addiction.
If we are worried about our bodies, why is there no war on obesity, toxins, pollution, et al.? Why are not toxic polluters, negligent through the addiction of maximizing profits, given the death penalty for their misdeeds?
If one chooses to run from reality, either through drugs or superstition, so be it. When subjugated groups, such as minorities, sell drugs, who can tell them they are wrong for doing so? Are the poor and/or unemployed evil for meeting a demand and in doing so making the money they cannot make in the mainline economy from which they have been excluded?
