if i wanted to start a small business where i test people's drugs for fent/pcp/meth/clam or whatever, what sort of reagents would i need to buy? I realize this is sort of an open ended question, i'm just sort of looking for general suggestions for pretty much any drug testing reagent that tests for something. there's pretty much nowhere that you can safely get your drugs tested around where i live & i really want to do what i can to help. i feel like i could save some lives with this. especially looking for something that can detect if my jenk's been cut with dog pills
