Does cocaine show up same as amphetamines on pissed test?

no it does not. although the effects of cocaine and amphetamines are similar, the chemicals are still different and therefore a urine test would yield results specific to the compunds ingested. the excreted metabolites from cocaine use are different from those associated with amphetamine use, and as a result they would both produce different results on a drug test. assuming your cocaine isn't cut with amphetamines you wont come up positive for amphetamines, and if you take amphetamines you will not test positive for cocaine.
