i have done plenty of ketamine.
it is not a "horse tranquilizer" - it is a disassociative anesthetic and was popular in the US until it became scheduled, so now it is used for animals only. a small bump will cause general numbness throughout the body and a general sense of well being. a jar or several bumps (depending upon tolerance) will send you into a "k-hole". your brain is completely disassociated from your body and hallucinogenic effects take hold. you are completely paralyzed. it is typically insuffalated though it can be taken intramuscularly though you would need to have someone else inject you as you'd pass out before finishing the plunger.
i enjoyed ketamine a great deal, but it did rewire my brain a bit. it is also highly addictive, extremely expensive, and difficult to acquire. it cannot be synthesized like most recreational drugs.
