If you don't have the right to your own body, then there aren't rights. It's the axiom.
I'm in favor of drug use (at least almost all), tattoos, body modifications, trying experimental medicine, everything that affects your body. I can see drawing the line at "doing this thing could become a contagion so you can only do it in BSL-4 isolation". But it's your body, your life, you want to spend it stoned or a voluntary amputee or whatever so long as don't take from me, then you should be free to do so.
