How long do bath salts stay in your system?

Answer 1

Surprisingly, I have found that 4-FMC (Flephedrone) and 4-MMC (Mephedrone) show up as Methamphetamine on the drug tests I have been using (to varying degrees). Typically, positive results would persist for a maximum of 2-3 days.

Answer 2

The effects of bath salts typically last 3-4 hours when ingested, but they can stay in your system for 1-3 days. It's important to seek medical attention if you suspect bath salts have been consumed.
