Certainly a fascinating slant on ketamine, more familiar to me from reports documenting benefit in patients with severe, treatment-resistant depression. In clinical applications the dose is very small vs. street use and not associated with the destructive gut and brain side effects described in the article. However it's not innocuous, hallucinations or psychosis, among other side-effects, are known, non-trivial risks.<p>It has been a drug of abuse in the US, but nothing like the near-epidemic proportions going on in China. If the article is accurately describing conditions over there, it suggests it's probably only a matter of time before we'll see it in N. America.<p>Kind of ironic in a way. Here in Oregon cannabis is now legal for recreational use, and other states will probably join the handful that permit sale and possession of the drug. Widespread abuse of ketamine with harmful outcomes might inspire a new round of a "war on drugs" just as unnecessary controls on cannabis are being reduced.<p>Perhaps it might lead us to think that not all "recreational" drugs should be regarded as harmless or the same as others, and one set of rules does not fit all.<p>Edit: fix grammar.
