I am posting this info both to help those doing tests for separating and identifying substances from plants, as well as for general harm reduction for those that use RCs and other substances. Please test any compound one hasnt extracted oneself and is sure of what it is. These tests are easy to buy and use for any common person, check links on the bottom!
