Too true. Unfortunately, in the eyes of almost all world governments, any drug that's enjoyable seems to automatically lose any medically useful properties it may possess. It's a sad situation that could be fixed with real drug education and not the one-sided propaganda programs (D.A.R.E. and friends) that substitute for it.

You mean, apart from the bit at the end which says:

  The Home Office is reclassifying ketamine in the UK to be a class B drug, although it is already used in medicine for the treatment of back pain and as an anaesthetic.

And in humans, too! If you've had a colonoscopy, you may have been administered ketamine before the procedure.
