Can I get kidney stones and blater infection by using ketamine?

Ketamine. K has many side effects. It is not addictive but can produce severe withdrawal symptoms when people try to quit. It spasm the bladder and the ureters (tubes coming from the kidneys to the bladder), usually manifestations being confused by doctors to a urinary track infections. It can produce in time bladder ulcers, scaring and permanent damage.
Forgive my frankness. Indeed you can. Ketamine metabolites turn into sludge in the kidney tubules and have provided the nephrology community with a new type of stone and a reason for obstructed kidneys. If you must use ketamine, drink plenty of water. You've read about the pioneers of ketamine "mind journeys" who ended up dead from their use. And you never know what's really in that bottle. It's your life.
