The US overdose epidemic continues to accelerate despite extensive attempts to expand treatment for opioid use disorder and overdose prevention services. An estimated 100 306 people died of an overdose between April 2020 and March 2021, the greatest number of overdoses ever in a 12-month period.
1 Reasons for increased overdose rates are multifactorial and include the increasing dominance of fentanyl in the opioid drug supply and its addition to psychostimulants, increases in psychostimulant use that appear to exacerbate the risk of overdose,
2 and the COVID-19 pandemic.
3 The age-adjusted rate of drug overdose deaths involving psychostimulants, including methamphetamine, increased 10-fold from 0.5 per 100 000 people in 2009 to 5.0 per 100 000 people in 2019.
4 Although both cocaine and methamphetamine combined with opioids increase the risk of overdose,
5 methamphetamine is associated with an increased risk of overdose, regardless of opioid use.
