What is Ketamine? 

Ketamine is a short-acting anesthetic with rapid onset effects that is used in both humans and animals. Sold commercially in the United States in powder and liquid forms, Ketamine, is considered to be a “dissociative” anesthetic because of the feeling of being detached from reality that patients under the influence have described. It has been said to alter a person's perceptions of sight and sound and can cause slight hallucinogenic effects. Ketamine has gained popularity in recreational drug users because of its euphoric effects and the detachment from one’s pain or environment. Illegally distributed Ketamine often comes from a legitimate source, in particular, veterinarian clinics.
