By Will Sullivan Paul Hammersley, an Addiction Recovery Resource Specialist in Malden’s Health Department, says he sometimes feels as if he’s “working a pandemic during a pandemic.” As a result of economic and emotional stressors exacerbated by the COVID-19 pandemic, more people are dying from drug overdoses nationwide. The Centers for Disease Control estimates that the country was on pace for more than 80,000 drug-overdose deaths in 2020, more than any other year. The majority of these deaths will have been caused by opioids, a class of drugs that includes prescription medications like oxycodone (Oxycontin) and hydrocodone (Vicodin), as well as fentanyl and heroin.  According to Hammersley, after only three people died from an overdose in Malden in 2019, that number jumped to 13 in 2020, with five of those deaths occurring in the second half of December. Nearly all overdoses in Malden are caused by opioids.
