Check your citation, it refers to overdose deaths nationwide between the period of June 2019 until May 2020. The vast majority of those deaths occurred
before there were lock downs in the end of March and beginning of April 2020.
Your stats include about a month or two of lock downs at most.
My stats refer to the period between January 2020 and the end of December 2020 in a single state. I'm not about to dox myself, but we can use another state's data to illustrate the same point. In NJ, there were 3,021 overdose deaths in 2019, and in 2020, there were 3,046 overdoses, an increase of only 25 deaths[1], or 0.83%.
> "Overdose deaths involving cocaine also increased by 26.5 percent" [0]. How do you explain that one?
Cocaine and psychostimulants are becoming increasingly popular year-over-year. For example, the CDC reports that psychostimulant overdose deaths increased by 37% in 2017[2], and drug overdose deaths involving cocaine increased by more than 34%.
The CDC reports that from 2009 to 2018, cocaine overdose deaths nearly tripled[3], and between 2014 and 2018, the rate of drug overdose deaths involving cocaine with opioids increased at a faster pace than the rate of cocaine deaths without opioids. If you look at the compiled data[3], between 2015 and 2018, cocaine overdose deaths skyrocketed.
Part of the trend might be related to increasingly adulterated cocaine[4] with fentanyl and designer stimulants over the past few years.
