I don't disagree with your general intent. Let's not put cocaine and amphetamines on the same level as caffeine though. Some drugs are orders of magnitude more harmful than others. Alcohol would have to be erased from human society before caffeine ever entered our crosshairs.

Also, you should remember my comment was about the route of administration. A drug you take is your choice. An airborne drug works its way into your system whether you want it or not.
