From my research on the subject, ketamine bladder only happens if to chronic, long term users using several grams a week. Most of the studies of using ketamine to treat depression are using under 1 gram per month. Infrequent use of ketamine (less than once a week, less than 1 g), whether medical or recreational has no negative side effects. It's also unknown whether it's actually caused by ketamine, or by whatever is being used to cut street ket.
