I know with MDMA they can sell you methylone, LSD can be nbomes, etc., but is there something that can imitate meth due to similar effects without being meth? I never hear of testing kits for meth so I wonder if it's ever a concern that it's fake when you receive it from a vendor. By the way, I'm speaking of meth in crystal form, not powder that could be cut with a number of stimulants or research chemicals. Basically, if I get a shard and it's effects match meth, is that the only possibility? Just wondering if there's any chance I've been ripped off in the past and never even knew it.
Marquis Reagent tests for methamphetamine. It will turn a redish color.
