ketamine and consent, where do you draw the line

this is a real concern not a hypothetical. ketamine has crept into a couple of social circles weve drifted near and its presented as casual, almost like a glass of wine. but the dissociative quality of it makes me deeply uneasy in a lifestyle context. someone whos in a k-hole isnt giving meaningful consent in any sense i recognise, even if theyre saying yes with their mouth. ive watched it happen in a different friend group years ago and it stayed with me. how do you lot handle being at a party where its around, do you leave, do you stay sober and play with sober people only, where's the line for you. genuine question not a sermon...
