We didn't know about secondhand smoking when we were young…

I would guess that the pandemic of ADHD comes not from smoking but from kids not playing outdoors, cycling to school, climbing trees, etc - all that extra energy just rioting around their little bodies and minds.

The one thing that worries me about the push to legalise cannabis is that it may get a lot more people smoking dope - and I have no doubt whatsoever that dope smoke is just as dangerous as tobacco smoke.
