Some users have been known to take higher doses as a way to control the bladder pain caused by ketamine, which in turn increases the risk of bladder damage and pain.
Abdominal pain or ‘K cramps’ have been reported by many long-term users.
Evidence of liver damage due to regular, heavy ketamine use is emerging. The liver has a range of important functions, such as cleaning your blood and removing toxic substances.
It can make you physically incapable of moving. You can feel completely detached from your body and surroundings, which has been compared to having a near-death experience. This is sometimes called “entering the k-hole”.
Injecting ketamine can damage the veins and can cause serious problems such as abscesses (swollen areas of tissue that are full of pus) and blood clots. Sharing injecting equipment, including needles and syringes, risks infection with hepatitis C and B viruses and HIV.
