Bad Chik:
Ketamine is a dissociative anaesthetic, developed in the mid 1960's, used primarily for veterinary anaesthesiology. Although Ketamine is not used medically on humans much because it induces psychedelic episodes in patients, it is still used for some limited human applications because it does not depress breathing or circulation. Ketamine is used recreationally primarily as a snorted white powder and for therapeutic and psychedelic use it is often injected intra-muscularly (IM). Its effects range (at lower doses) from mild inebriation, dreamy thinking, stumbling, clumsy, or 'robotic' movement, delayed or reduced sensations, vertigo, sometimes erotic feelings, increased sociability, and an interesting sense of seeing the world differently to (at higher doses) extreme difficulty moving, nausea, complete dissociation, entering complete other realities, classic Near Death Experiences (NDEs), compelling visions, black outs, etc. Ketamine is also known for being more psychologically addictive / compelling than most psychedelics and it is not uncommon to hear of users who take it once or more daily.
