Drug Screening

3-MMC

3-MMC is, according to a Dutch study from 2026, a synthetic cathinone and an isomer of mephedrone (4-MMC): 3-MMC has the same atoms as mephedrone, with one group in a different place. According to that study, 3-MMC became popular in the Netherlands because of its stimulant effect and because it was legal at first. According to the Trimbos Institute, 3-MMC can bring cheerfulness, an upbeat feeling, less anxiety and more self-confidence. According to the Trimbos Institute, 3-MMC can also bring muscle and jaw tension, a dry mouth, restlessness and sleeplessness, and craving, the urge to use again and again. Only a test shows whether 3-MMC has been in the body; in a laboratory, that is possible in blood and urine. Unilabs publishes no cut-off or unit for 3-MMC in urine and gives "n.aant.", not detectable, as the expected result of its MMC panel. This 3-MMC test looks for 3-MMC in urine.

Drug Screening

Phenibut

Phenibut is a substance that resembles GABA, a messenger substance of the nervous system, and according to a 2024 review it acts mainly on GABA-B, GABA-A and beta-phenethylamine receptors. In Eastern European countries, phenibut is a registered prescription medicine according to a 2024 article, used against anxiety, insomnia and alcohol withdrawal among other things. With long-term use, phenibut can cause tolerance according to the review, and stopping suddenly can trigger a withdrawal syndrome that can need treatment. Only a laboratory test shows whether phenibut is in the body, and a standard drug screen does not look for it, according to the review. None of the laboratory guides read for phenibut names a reference value: Unilabs looks for phenibut in a urine screen for new psychoactive substances, and Diagnostiek voor U reports phenibut in urine in micrograms per millilitre (µg/mL).
