Tobacco companies had a very very weak argument that people born after a specific date used it on purpose (after the warnings were required on the product). Before that date, people believed it was safe due to ads.
But plastic people have no such argument. Health issues are yet to be fully confirmed. But after about 50 years of plastic being everywhere in the environment, we see alarming increases in many health issues among the young. The young have been exposed to plastics since conception.
To me, that is a rather big coincidence.
Are they related ? Only more research will tell, but everyone now has mirco-plastics in their systems.
Seems this is like the mercury build up that happen a long time ago. Eat organisms with micro-plastic in their system, it builds up in your system.
