Hey, we are in dire need of a dangerous interactions page so it would be great if you could help. The original page was deleted because it was mostly incomplete. There's no specific format that you would need to follow. I really like the idea of having a drop down menu so please follow up with me if you create this. :) I use the drugs.com one a lot.
If you need a guide for determining which substances are dangerous to combine, we have dangerous interactions sections on all of our substance pages in the toxicity and harm potential sections. For example:
https://psychonautwiki.org/wiki/Nifoxipam#Dangerous_interactions
TripSit also told us that we can host their dangerous combinations chart on our wiki if we give them full credit. http://tripsit.me/tripsit-releases-v3-0-of-its-drug-combination-chart/
Thanks!
BTW, one question: Does "IPA" in your IPA extraction guide stand for isopropyl alcohol?
