Although prescriptions for nimetazepam have decreased, abuse of the drug is still significant in Brunei, Singapore, Malaysia, and the Philippines. It is commonly used in combination with methamphetamine and MDMA (Ecstasy) and opiates (especially heroin or morphine). The strict legal restrictions nimetazepam is subject to in Malaysia has made the drug scare, but many pills sold as nimetazepam in the black market are counterfeit. Diazepam and nitrazepam are among the most commonly prescribed benzodiazepines in the region, and as a result, they are commonly diverted and sold on the black market, often as nimetazepam.
