Interestingly, at least in the US, a take-home prescription for ketamine is already suprisingly cheap - $38 USD for 100ml: https://www.drugs.com/price-guide/ketamine

At least near me, there are "ketamine centers" that already to ketamine clinics - $500 per session, and insurance doesn't cover it. Ends up being around $3000. I haven't done it, so I can't comment on its effectiveness.

It's pretty lame that the cost difference is so large. I guess the barrier is a psychiatrist's willingness to prescribe. Maybe all of this research will open up psychiatrists to prescribe take-home ketamine more readily?
