"Reflecting consumer demand, the market in new benzodiazepines appears to have grown over the past few years. The EMCDDA is currently monitoring 23 of these substances, including six that were reported for the first time in 2016 and three during 2017. While the overall number of seizures reported by law enforcement during 2016 decreased compared with 2015, the quantity reported increased. More than half a million tablets containing new benzodiazepines such as diclazepam, etizolam, flubromazolam, flunitrazolam and fonazepam were reported during 2016 — which was about 70 % more than in 2015.
Increasing Involvement Of Benzodiazepines In Opioid Overdose Mortality In The US, 2011: "In 2011, 5,188 opioid-analgesic poisoning deaths also involved benzodiazepines (sedatives used to treat anxiety, insomnia, and seizures), up from 527 such deaths in 1999 (Figure 3). From 2006 through 2011, the number of opioid-analgesic poisoning deaths involving benzodiazepines increased 14% on average each year, while the number of opioid-analgesic poisoning deaths not involving benzodiazepines did not change significantly."
