Does white rush bath salts show up in drug tests?

In my experience (only one time use) like four hours or better and it was an intense high. I've done everything else elicit and this was comparable. I wouldn't recommend it though. I heard there con be some reactions from some people plus you can only "introduce" it 1 of 2 ways into the body. It doesn't show up in a UA... yet. But it will soon enough. As far as the half life like meds and drugs, there is not yet any FDA testing because it is "Not intended for Human Consumption." If I had to make an educated guess by the amount of time you feel the effects as to the half life, I would guess around 10 hours for the half life. Now remember, because we don't know what all is in it for sure, we may not want to treat the estimated half life like that of regular meds. we don't know how our body breaks it down, ( body fat, liver, etc.) so all of that matters. I would suggest not over doing it just cuz the first "go round" has worn off. Hope I answered something for somebody.
