Can hair follicle drug test tell the difference between klonopene and xanax?

Hair follicle drug tests generally cannot distinguish between specific benzodiazepines like Klonopin (clonazepam) and Xanax (alprazolam). These tests typically identify a class of drugs rather than individual substances. However, if the testing laboratory performs more advanced analysis, such as mass spectrometry, it may be possible to differentiate between them. Nonetheless, standard hair tests primarily indicate the presence of benzodiazepines without specifying which one.
