The Smallest Drugs Here is the updated version of the "smallest drugs" collection that I did the other day. Here are the criteria I used: the molecular weight cutoff was set, arbitrarily, at aspirin's 180. I excluded the inhaled anaesthetics, only allowing things that are oils or solids in their form of use. As a small-molecule organic chemist, I only allowed organic compounds - lithium and so on are for another category
My serotonin and dopamine tattoo. I struggle with overwhelming depression and crippling anxiety, and these two are the “happy chemicals” in your brain. Just a constant reminder that my happiness is my choice, and that I can overcome anything thrown at me. Done by Tattoo Dougie at Inner City Tattoo in Pensacola, Florida.
