Ketamine for depression. Where do I sign up?

I found this via WarrenEllis.com

In which researchers have found out that in clinical trials Ketamine had an almost immediate effect as a treatment for depression.
Sounds like good news to me.
Although the researches do put the following proviso in:

"The team says ketamine, in its current form, would not be appropriate for medication because of side-effects at higher doses, which include hallucinations and euphoria."

Is it just me or does anyone else think that people suffering from depression might appreciate a bit of hallucination and euphoria?
