Legal or Illegal?

Yes. Highly illegal. One to ten on illegality; 10.
In United States, if you plan on introducing research chemicals into your [or anyone else's] body using any method, that is considered a 'thought crime' and is punishable by imprisonment and/or long-term imprisonment.

 

Oops! Glad you pointed that out to me. I wont be considering doing that then. If I was still entertaining the idea, ,after much research, I would have gone with methoxetamine. Seems that it has been very effective in treating depression. I would have been concerned about the hallucinogenic qualities. I did LSD once 24I years ago. It took about 6 or 7 years to get past it but I've never been completely removed from the experience. It was hell on earth.
