A compilation of preprints, peer-reviewed studies, and datasets documenting SARS-CoV-2/Covid-19 patients' smoking status - only the ones with at least 1000 patients.
I smoked for a number of years. I liked it. I didn't want to quit, but for years I thought I should. I tried cold turkey, gum, patches. Didn't work for even a day.

I first heard about e-cigarettes late in 2009. I looked into them, but saw that ecigs containing nicotine were not legal in Canada. I knew they wouldn't work without nicotine, so I forgot about them.

In 2014 I saw this CBC piece. Nicotine vaping was a possibility after all. I didn't know anyone who vaped & the nearest vape shop was over 200 km away. I researched. A lot.
This got off to an extremely weak start. The middle of this century stuff is a complete cop-out, and it completely ignores the fact that much is known already.
Khara seemed to have a good handle of the state of the evidence most of the time. To me, the notion that e-cigarettes should only be a last resort looks unethical though.
Underrated point: most conclusions about vaping are based on what's known about smoking. Bad idea imo.
