Kratom is heavily promoted as a legal, undetectable, safe drug that can be used to come off stronger drugs. It is not yet illegal in the US but the breakdown products of kratom can be detected with some drug tests. If you want a test for that you would need to ask for it.
All-natural Kratom does not show up on a drug test unless someone is specifically testing for the alkaloids that are contained with it. As far as anyone knows, not a single entity is currently doing this at this point in time. Therefore, Kratom does not share anything in common with anything else that might be tested for under 99.9999% of all circumstances. However, it is advisable that you stick with Kratom that has not been adulterated by other garbage and can be guaranteed to be all-natural, from vendors such as Kratom Wellness and the others. Whatever you do, never buy extracts, tinctures, or other ridiculous stuff!!
