If you look through the more active threads you'll see a lot of posters looking out for one another.
Very frequently there will also be advice given, like "you should micron filter that" or "heads up that's serotonin syndrome territory" et cetera
In addition, many posters will have a caveat addendum to their post if they are aware that what they are ingesting would typically be very unsafe. And multiple posters tend to include vitals that theyve checked when posting about large combinations, which is nice.
I'm not trying to claim that we are all people of 100% safe drug taking, only pointing out that in general users in this subforum look out for each other.
And questioning safe use by others is never taken in bad form.... Someone might say "yo man that is super dangerous, watch out!" And I've never seen a person being talked to like that respond with a "yo fuck you man!". Surprisingly this is the least toxic subforum on the site. Personal opinion there of course.
