15g per day is a ridiculous amount. Though not the most common ketamine induced bladder damage has been observed to occur in a few months of weekly recreative use of insuflated doses of 1-2g over the weekend. On the other hand some heavy chronic users in the several grams daily range had little to no damage after years of abuse so YMMV.
