Harm Reduction: Comprehensive Guide to Managing Bad Trips and Overdoses (Part II)
This is part two of the harm reduction table. If you missed the first one (Comprehensive Guide to Managing Bad Trips and Overdoses (Part I) - /u/OlgaMars) , it covers the basics like how long different substances last, what to do if things go wrong, signs of overdose, and how to help someone come down safely. This second part continues with more substances and tips to stay safe and informed.

Harm reduction isn’t about encouraging use, it’s about making sure people stay alive and as safe as possible if they choose to use. This table is just one tool to help with that. No guide can cover everything, so it’s important to stay aware, trust your instincts, and look out for each other.
Support your friends, know your limits, and don’t be afraid to ask for help when it’s needed. Community and care go a long way.
Stay informed, stay safe, and look out for each other.
