Maybe ALCOHOL?

I've not read this but go ahead and give it a look>>> http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1470475/

Alcohol in its pure form is addictive. The thin red line between addiction and hearty-party was found to be the effect of a hangover. Hangovers occur when the brew contains a little amyl alcohol. Fractional distillation, can seperate amyl from ethyl alcohol, thus producing an addictive alcohol with no hangover. People exposed to pure ethyl can easily drink themselves to death without a hangover from amyl to push them to quit.  The effectiveness of amyl in alcohol beverages suggested that the alcohol beverages would be acceptable in the market providing amyl is in the product. Religiously the product had to have a penality for over consumption like guilt for sin. So the conditional inclusion of amyl brought alcohol beverages back into common use. The problem we now have with Vodka is the same problem we had here…no amyl in much of that brew. Amyl is required by federal law at low levels by process. But Russian Vodka has produced the same problem there that we had here…and I have not seen the compliance of  Russian vodka to the congressional ruling on this matter.    

The embrace of prohibition was because of alcohol addiction and rising death tolls from over consumption. Pure ethyl does not produce a staggered gate or slurred speech.  There is no hangover and drinking yourself to death is quite easily done.
