There may be help for Mexico, because Mexico has a cherished tradition of ignoring laws.
CASAA sent out this link to this interview with Roberto Sussman, a PhD physicist who quit smoking by vaping, and says he is "tired of people mopping the floor with junk science".
He talks about Hugo López Gatell, who sounds a lot like Anthony Fauci and equally disliked. He says Gatell is making a dedicated chew bone of vaping, now that the pandemic is over and he no longer has the spotlight.
Mexico has a smaller version of our CASAA with the unlikely name Pro Vapo, for consumers fighting for access to tobacco harm reduction products:
PROVAPEO MÉXICO – Información verídica basada en fuentes científicas y médicas sobre el cigarro electrónico
The most interesting thing that comes out in the interview is how the anti-vaping law started as a ban on a candy called "chocolate cigarettes", and later was just conveniently slapped onto the electronic cigarette.
He mentions the undue influence of the WHO on vaping policy in Mexico, and how the media there is slanted toward vaping as a dangerous addiction, never admitting it as a safer alternative to smoking, just as the media behaves here.
You have to get past the first few minutes of schmoozing about the weather while all the participants get connected. Really interesting.
