Several people have asked what my research is about. It is a private study I am considering on the social uses of stimulants and the effect of criminalization on the same. My thesis is not fully cooked yet but I'll need to establish links with growers, suppliers, resellers and users to make much headway. I also have to find the funding.

Meanwhile, consider this: anytime that human beings have congregated to form a community they invented two things that have no evolutionary/survival value, namely: stimulants (including drink) and religion. Why?
