I don’t think there’s such a lag to discover the negative effects. A couple of years perhaps, but not decades.
What you are pointing at is the time when these negative effects can’t be rejected by their respective industries. Teflon and cigarettes had the scientific experiments done pretty early, and from there it was the different companies fighting the results to affect public perception.
New products spreading successfully in our society always have a set of companies getting big and powerful, with a critical interest in killing any attempt to paint their products as nefarious or needing caution. Of course it will take decades to get them to acknowledge they’re screwing the whole population.
PS: of course any new technology is always a trade-off, and the risks can be worth the upsides. For Teflon, even knowing the issues, many people will still chose to use non-stick for sheer convenience. BTW it’s not just “high” temperatures (“high” meaning heating your pan too much for 2~5s from memory), you’ll get contamination on physical damage and wearing off of the coating as well.
