will any of these prescribed diet pills make me have a positive drug test?
Diet pills years ago used to have methamphetamins which could possible show on drug tests. Meth is also found in crystal meth which is an illegal substance. Most of these diet pills have been pulled off the market, but some consumers have stockpiled these pills and still use them.
In addition, certain diet pills can still lead to a false positive if they have the ingredients similar to opiates or amphetamines.
