GHB aside I wouldn’t even call it particularly dangerous, it’s just blissfully wrongheaded. Ketamine is a dissociative anaesthetic, and it does what it says on the tin: it takes however your mind is at that moment and just brutally lops off all the connections you normally anticipate it having with your body and other bits of itself, with various interesting consequences for mind and body both. Alcohol is alcohol, it’ll depress your euphoria to some extent but it is also in itself sugar and obviously will make you drunk on top of the (significant) remaining effects of the stimulant - rather than calm down, you are far more likely to get outrageously mad and try to punch a stranger, poorly, because already the whole point of abusing most stimulants, euphoria aside, is to turn you into the world’s sharpest spoon.
This whole situation is making me so glad I stopped taking drugs and never learned to program
Born too young to be made to learn how to program in school
Born too old to lose my code monkey job to a literal mechanical code monkey in a mutually disastrous management fuckup
Born just in time to burn out on drugs and alcohol and watch the machine revolution from home
