Data are from two monthly-count sources newly-posted by the CDC on February 3, 2020.

Neither data set provides cause of death codes for the Drug Overdose category, which is a bit odd, as codes are provided for other causes in the files

3/12
I emailed the CDC yesterday to inquire about what all is included in Drug Overdose in these data.

They said, "Overdose deaths [in the dataset] contain mostly unintentional deaths, but also suicide, unknown intent and a few homicides."

Due to the footnotes & that email I'm not positive that the two new monthly datasets are comparable.

However, were's the latest 2020 data https://data.cdc.gov/NCHS/Monthly-Counts-of-Deaths-by-Select-Causes-2020-202/9dzk-mvmi alongside the data 2015-2019 CDC Wonder data: https://wonder.cdc.gov 

5/12
If you're wondering, the Wonder data uses underlying cause-of-death codes X40–X44, X60–X64, X85, and Y10–Y14.

I referred to this December CDC publication for those codes. https://emergency.cdc.gov/han/2020/han00438.asp

No matter what, the CDC has already recognized the role of the pandemic in accelerating opioid deaths. Per my email with the agency, the data in the files I've used DOES include suicides that involve drugs.

Are these "lockdown deaths"?

I think it's at least fair to say they are lockdown-assisted deaths.

Even if we assume these were folks who were already struggling with addictions, let's consider how pandemic-response may have played a role...

8/12
1) People were furloughed or unemployed.
2) People were cut off from in-person therapies/treatments.
3) The Government sent $600 checks that may have be used to purchase more drugs and alcohol.
4) People were at home more - where I assume drug use tends to occur.

9/12
I've tweeted previously about increases at deaths at home in 2020 - which were NOT "displaced" from other locations, as some folks have alleged.

My guess is that drug overdose deaths occur largely at home.

Finally, I don't know if the Drug Overdose deaths in the CDC's monthly files include any COVID deaths. (I know they do in Cook County: https://twitter.com/EWoodhouse7/status/1351411848088854531?s=20

Footnotes imply not, but I've requested that info from them for clarity and am awaiting a response.
