Muscle relaxers and drug test?

Most drug screens are looking for controlled substances. Most muscle relaxants are not classed as controlled substances. Soma can be classed as a controlled drug in some states though. It is the only muscle relaxant that is unless you are using a benzodiazepine for a muscle relaxant (f.i valium or diazepam). Drugs like Flexeril, zanaflex, baclofen, robaxin, skelaxin-they are not controlled drugs and they probably are not going to be looking for these in a drug screen. Most screens are looking for marijuana, amphetamines, benzodiazepines, opioids (both opium derived and thebaine derived, so morphine, codeine, hydrocodone, oxycodone, hydromorphone, oxymorphone etc.) barbiturates, PCP. mescaline, LSD, MDMA or Ecstasy, cocaine, etc. Does that help?
