The CDC graph shows that in the 12-month period to April 2023 it was 110k, and that reduced to 100k in the 12 months to April 2024. That is absolute - isn't it?
Oh, OK. I guess there are different ways to use the word "relative". Certainly a decline when zoomed in can look like part of an increase when zoomed out. But to be clear, this isn't one of those decline-in-the-rate-of-increase deals, which is what "relative" means to me. (Great news everybody! The rate of increase in the increasingly large numbers of deaths is slowing down!)
no. That is relative to 2023. There isn't going to be an absolute decrease because the chart started at 0 and we can't go below 0.
only absolute increases (increases that go over historical highs), relative increases (increases that do not go over historical highs), and relative decreases.
Indeed, it's probably not due to marijuana legalisation, unless the resulting decline had a four year lag period for some reason, which I won't attempt to argue.
I’d be more surprised if the effect was immediate. Addiction takes years to develop, and years to recover from. I would also expect marijuana legalization to have more impact on (potential) future drug users than people already addicted to opioids.
