USA. New Potent Synthetic Opioid—N-Desethyl Isotonitazene—Proliferating Among Recreational Drug Supply in USA 

N-Desethyl isotonitazene is a new synthetic opioid bearing structural resemblance to isotonitazene and recently emergent nitazene analogues. N-Desethyl isotonitazene is dissimilar in chemical structure to fentanyl, the synthetic opioid most commonly encountered, but this subclass of new opioids has been proliferating in the wake of the scheduling of fentanyl analogues. N-Desethyl isotonitazene is a known metabolite of isotonitazene; however, it has now emerged as a primary drug in its own right. Most nitazene analogues encountered retain opioid receptor activity and potency similar to or greater than fentanyl. (CSFRE – The Center for Forensic Science Research and Education, USA, 23.01.2023)

Israel. Earliest evidence of opium use found in burial site in Israel

Evidence of the earliest use of the narcotic opium has been found in an ancient burial site in Israel.

Traces were discovered by archaeologists in pottery vessels at the complex in Yehud, about 11km (7 miles) south-east of Tel Aviv.

They say the containers date back about 3,400 years, apparently having been used in local burial rituals. 

The site was used by inhabitants during the period when the land was known as Canaan. (BBC, UK, 20.09.2022)


Could Opium Gum be the Solution to the Overdose Crisis?

The prohibitionist regime surrounding the adult use of drugs has had devastating impacts on individuals, communities, and entire regions, spurring corruption, deteriorating the rule of law, and resulting in numerous human rights violations.  The harms of prohibition have been broadly documented and yet, policy makers and politicians continue to uphold the status quo, even as policy innovations demonstrate a new and progressive way forward. 

The illegal heroin market has dramatically transformed in the last few years, with the substitution or adulteration of fentanyl “poisoning” the market and spurring an overdose crisis tragically seen in the United States and Canada, among other nations. Within this context, as overdose deaths rise, the price of opium gum, as it is known before it is transformed into heroin, has fallen by 80% since 2018. This drop in prices directly impacts cultivating communities in Mexico, which use poppy crops as a complementary cultivation along with subsistence farming. 

As researchers and advocates for drug policy reforms centred on people, human rights, sustainable development, harm reduction, pleasure, and social justice, we have been working in Mexico to highlight how opium gum could become one of several opiate-based products offered within a legal market that simultaneously combats the poverty of cultivating communities and prevents overdoses of people who inject drugs.

Kanada. CCENDU Drug Alert - Nitazenes

What Are Nitazenes?

Nitazenes are potent synthetic opioids from a drug class known as benzimidazole-opioids.

Some nitazenes are estimated to be several times more potent than fentanyl.

They were developed 60 years ago as potential pain relief medication, but were never approved for clinical use.

They were first identified in the unregulated drug supply in Canada in 2019.

They typically appear unexpectedly in drugs expected to contain other, more traditional opioids (e.g., fentanyl, oxycodone tablets or “down”), often alongside non-medical benzodiazepines (NMBs). (Canadian Centre on Substance Use and Addiction, 2022)
