What is Erimin 5?
Erimin 5 is a street name for a drug called Nimetazepam, a type of Benzodiazepine manufactured in Sumitomo, Japan. It is an intermediate-acting hypnotic drug. It was first synthesized in 1962 by a team from Hoffman La Roche. Since early November 2015, it has ceased to be manufactured in Japan. It was prescribed for the short-term treatment of patients with severe insomnia, but in recent times, patients have been prescribed other hypnotics like Etizolam and Flunitrazepam to treat their illnesses due to the addictive and harmful consequences of Nimetazepam use. Erimin 5 is most popular in Singapore, Malaysia, and Indonesia. It is also known on the street as "Happy 5". The effects of Erimin 5 have a soothing effect on its user. Addicts do not have healthy coping mechanisms due to the nature of addiction. Erimin 5 sets off addiction in addicts because it feeds what is lacking in their brain: dopamine. It does so because the drug is a hypnotic, anxiolytic (it eradicates anxiety), sedative, musculoskeletal relaxant, as well as an anticonvulsant substance. Rarely do addicts use Erimin 5 by itself. It is used along with other drugs. Some users drink alcohol alongside taking Erimin 5. It is also a come down pill for Ecstasy (MDMA) and Methamphetamine users.

It is usually taken orally in tablet form. The fact that it is manufactured as a tablet of 5mg gives it the street names of Erimin 5 and Happy 5.

Nimetazepam is a hypnotic drug which is a benzodiazepine derivative. It possesses strong hypnotic, anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. It is sold in 5 mg tablets known as Erimin-5. It is used to treat insomnia. Nimetazepam has a reputation for being particularly subject to abuse (known as 'Happy 5', sold as an Ecstasy replacement without a hangover), especially by persons addicted to amphetamines or opiates. For this reason it is no longer sold in most Western nations, but is still a significant drug of abuse in some Asian countries such as Japan and Malaysia. Nimetazepam is the only benzodiazepine to be subject to legal restrictions in Malaysia, and due to its scarcity, many tablets sold on the black market are in fact counterfeits containing other benzodiazepines such as diazepam or nitrazepam instead.

Generally prescribed for the short-term treatment of severe insomnia in patients who have difficulty falling asleep or maintaining sleep. The sole global manufacturer of Nimetazepam (Sumitomo Japan) has ceased manufacturing Erimin since early November 2015. Taken orally, Nimetazepam has very good bioavailability with nearly 100% being absorbed from the gut. It is among the most rapidly absorbed and quickest acting oral benzodiazepines. There is a risk of misuse and dependence in both patients and non-medical users of Nimetazepam. The pharmacological properties of Nimetazepam such as high affinity binding, high potency, being short to intermediate - acting and having a rapid onset of action increase the abuse potential of Nimetazepam. The physical dependence and withdrawal syndrome of Nimetazepam also adds to the addictive nature of Nimetazepam. Nimetazepam has a particular reputation in South East Asia for recreational use, at around USD 7 per tab.
