Occasional use of K is not too harmful but when it is used regularly or on a daily basis, it can become as dangerous as any other addictive drug. People often start taking it to forget their problems or cope with stress. Heavy use of ketamine can lead to bladder damage, which is irreparable in some cases.
Although it can give you a trippy feeling, K is actually a tranquilizer that numbs your body, which means that you can seriously injure yourself without realizing it until much later. If you take too much K, you can go into a “K-hole,” an experience involving hallucinations, feelings of paralysis, and a loss of a sense of time and space. However, there have been no reported cases of anyone not coming out of it. Like other chemicals, K could lead to decreased inhibitions; you may forget about using condoms and put yourself at risk of picking up or passing on an STI or HIV. Similar to G, if you are in a vulnerable situation, this could leave you open to sexual assault.
