Quote:The effects of a ketamine 'high' usually last an hour but they can last for 4-6 hours, and 24-48 hours are generally required before the user will feel completely "normal" again. Effects of chronic use of ketamine may take from several months to two years to wear off completely. Low doses (25-100mg) produce psychedelic effects quickly. Large doses can produce vomiting and convulsions and may lead to oxygen starvation to the brain and muscles; one gram can cause death. Flashbacks may even occur one year after use. Long-term effects include tolerance and possible physical and/or psychological dependence.
