LETTER TO THE EDITOR: First scientific report of a new derivative of street heroin in east of Iran

Drugs and chemicals are easily available in Iran. Therefore, drug abuse and addiction are common [1]. Iran is a significant consumer of opium, and generally of opioid derivatives in the world [2]. Street drugs are being adulterated with lead, steroids, thallium and … for economical benefits [3,4]. This will lead to further complications. Development of tolerance to opioids in addicts leads to increase the dose or abusing more potent drugs or more harmful routes such as injection. More potent drugs are occasionally launched into the markets [5]. Opioid transitional illicit market is developing very fast. The pattern of usage is moving towards more high risk behaviors including using more potent agents and injections as well as newly developed drugs [6,7].
