Agreed. It's an absurd dose assumption. According to Erowid, a common dose is 30 mg to 75 mg.

I spent some time reading papers about ketamine before, and it seemed that all the negative side-effects (like bladder damage) are only ever observed in extreme cases where someone takes massive, abnormal doses for an extended period of time. I think it is not relevant to the vast majority of recreational users.
