That is a separate issue. I'm trying to understand what their specific health concerns are, why it is they feel any amount of vaping represents an antisocial immediate health hazard distinct from say driving while unhealthy, tired or whatever or taking drugs known to increase violent tendencies like alcohol.

There is something they feel is different and I'm trying to unpick what it is. Like is there a specific chemical they believe even trace vaping exceeds safe limits of? a class like VOCs but are they also afraid to be around a stove etc? Is it fear of lack of regulations meaning unknown contamination could be present? Is it lack of precedent of characterised harms? (e.g. standing next to a stove while cooking seems about as unhealthy as being near most* vapes but we tend to be comfortable with poorly ventilated stoves and not with vapes because stoves are boring).

They unfortunately seem to thing my curiosity represents some hostility, despite having stated that I am in favour of regulation and basically just have a couple of quibbles with this law ¯_(ツ)_/¯
