While bored at a party, my ears perked up a bit at the sound of a nearby conversation about psychoactive drugs. Wandering closer, I overheard a girl talking about an unpleasant experience she had recently had with a research chemical. I asked the first question that came to mind in such a situation:
"How much did you take?"
Her answer was, "One."
"One what?" I asked. "Do you know how many milligrams?"
To which she replied "Milligrams? I took one."
She didn't seem to understand that a unit of weight could be applied to the quantity of a drug, or that just because a substance came in pill or capsule form didn't mean she had no control over her dose.
