More young people took up the habit. More young peopke are smoking than pre pandemic. The decline in smokung has stalled.
You might argue with the nuance of the headline but I don't think it's misleading.
No - that is poor interpretation of the data.
Smoking pre-pandemic amongst young people was declining - smoking post-pandemic amongst young people is still declining. The issue is a one off spike at the point of the pandemic. More young people took up smoking in the brief period March-June 2020, but since then fewer young people are smoking with time. In fact the data are about proportions smoking, there is nothing in the actual article on uptake at all.
Also - the decline hasn't stalled (which implies no decline) it has reducing in rate.
e.g. June 2017 - smoking rate amongst 18-24 was 25%, by March 2020 that had reduced to 18%, so a decline of approx. 2.5% per year.
April 2020 - smoking rate amongst 18-24 was 25%, by Aug 2022 that had reduced to 22.5%, so a decline of approx. 1.1% per year.
But the post-pandemic trend is still a reduction.
