Rapid Rise of Fentanyl Overdose Deaths Sparks Fourth Wave Epidemic

The U.S. is experiencing a "fourth wave" of opioid overdose deaths, characterized by a significant increase in fentanyl mixed with stimulant drugs, according to experts. A study by UCLA found that the number of overdose deaths involving a combination of fentanyl and stimulants rose by over 50-fold between 2010 and 2015. Polysubstance use has become the norm, with fentanyl being mixed with various substances. The current wave began in 2015, with fentanyl mixed with stimulants becoming the dominant force in the overdose crisis. The combination of fentanyl and stimulants poses unprecedented dangers for drug users and challenges for healthcare providers. Overdose deaths involving fentanyl-stimulant combinations were highest among certain racial groups. Experts emphasize the need for increased awareness, access to naloxone (Narcan), and a concerted effort to address the ongoing crisis.
