What are the effects of ketamine on your bladder?

Ketamine makes the bladder wall more easily inflamed. If you snort ketamine often, your bladder wall may be constantly inflamed. The pain this causes is also known as k-cramp. Because of the pain, people tend to use more, which in turn causes more physical problems.
The constant inflammation can make your bladder wall less flexible due to scar tissue. You have to urinate more often. The inflammation can get so bad that the bladder is permanently destroyed and you need a stoma.
