Okay..how about this . That's plain stupid. let me tell you briefly about Ketamine and clear up some the partly true statements made here. 1. Ketamine is a potent sedative hypnotic drug that works on the NMDA receptor subtubtype. 2. It blocks polysynaptic reflexes in the spinal cord and inhibits excitatory neurotransmitters in the brain. Enough of that. 3.. It is a COMMON drug used for anesthesia every day for HUMANS. 4. it causes a phenomenon called dissociative anesthesia..simply put, you look awake but cannot respond to sensory stimuli. 5. Side effects: incresed blood pressure, increased heart rate,, combined with opiates (heroin,morphine) it causes respiratory depression (can't breath), in the catecholamine depleted state (low adrenaline..usually people who have been in intensive care unit for weeks..it causes direct cardiac depression( in vitro studies only, not the typical response in normal people.), it also causes bronchodilation and increased salivation. here is the bottom line from an Anesthesiologist/exercise physiologist: So if you do not want to be found dead somewhere, I advise not taking ketamine. Because when your heart rate goes to 150 and your blood pressure shoots through the roof, and that aneurysm in your head you never knew existed ruptures..just remember you took it against medical advise. P.S. Ketamine causes horrible nightmares.
