Having hallucinations and the feelings of invulnerability, abusers may unknowingly injure themselves due to anaesthetic and analgesic effects of the drug. It also lowers the heart rate and so with larger doses it can lead to oxygen starvation to the brain and muscles. Uterine damage / contraction is common for abusers of ketamine, sabotaging their normal life as they have to go to washroom often. Some abusers can even hardly make a 15-minute journey on vehicles, thereby sabotaging their normal life. Overdose of ketamine can result in unconsciousness and depressed circulatory and respiratory systems, sometimes causing death.
