I've got a hobby interest in synthetic cannabinoids. Also pyro. Heh heh. But I'm totally conservative and cautious.
When I was 10 I painted a square of poison ivy sap on my forearm. I then documented it over some days. This confirmed that the plant was indeed poison ivy and detailed the visceral response.
When I was gestating my mom studied weapons of mass destruction because my dad was studying law.
This perhaps explains my interest in forbidden and dangerous knowledge. I have yet to build a centrifuge :-P As a Master's engineer, I believe I could, given time and money.
But I have neither.
