New ‘designer drugs’ pose growing threat to road safety in the US
Researchers from the US have reported the initial results from the first quantitative study to focus on the contribution of multiple new psychoactive substances (NPS) from a range of classes to roadway crashes in the US. They found that 2% of 1,000 adults who visited one of two trauma centers in California within six hours after being involved in a roadway crash had traces of NPS in their blood. The most frequent were bromazolam, para-fluorofentanyl, and mitragynine. In most (88%) of these positive cases, NPS had been taken together with traditional recreational drugs such as fentanyl, methamphetamine, and cocaine. These results indicate that NPS are a new concern in roadway crashes and put lives at risk.
