Ketamine is among common psychedelics the most likely to lead to "bad trips", unfortunately. My anesthesiologist friends don't have much good to say about it (but of course they're not concerned with the anti-depressive effect).

SWIM always has very pleasant claymation visuals with K, as opposed to the usual soul-shredding ego death from LSD.

However prolonged use can cause bladder damage and (for the extreme mainliners) k-holes seem correlated to suicidal ideation, so as always tread carefully.

I doubt writing SWIM would ever work so I don't think you need to bother with it.

SWIM disagrees on grounds of plausible deniability, but you do you.
