New synthetic opioids (NSOs) are one of the fastest-growing groups of new psychoactive substances around the world.
I’ve observed many shifts within global drug markets, and I believe the increasing availability of synthetic drugs in the UK and Europe may represent a new chapter in illicit drug use here – with the emergence of nitazenes only adding to these concerns.
In June 2023, the UK’s most recent outbreak of deaths linked to synthetic opioids emerged in the West Midlands when drug dealers used nitazenes to fortify low-purity heroin.
Prior to 2019, there had only been limited reports of nitazenes in the illegal drug supply – including a “brownish looking powder” found in Italy in 1966; the discovery of a lab in Germany in 1987; several nitazene-related deaths in Moscow in 1998; and a US chemist illegally producing the drug for personal use in 2003.
While some studies have concluded that nitazenes are even more potent than the synthetic opioid fentanyl, which causes many thousands of deaths in the US, the NCA judges it a “realistic possibility” that the potency of both substances are “broadly equivalent” – making them roughly 50 times more potent than heroin.
