Of course many people are rushing to ban it before we fully understand it and like any controversial topic FUD is everywhere. But that doesn't mean careful small steps cant be made today.
Vaping vials of THC in Long Island, NY, as what happened in this article, isn't something sold through legal channels AFAIK though so I'm not sure how much an agency could help with this specific problem (other than to highlight them).
Everyone loves to bash Juul (which is a garbage product I'd never touch) and the big tobacco company which owns it, but there's tons of small mom-and-pop style juice makers, shops, and device manufacturers which run a big part of the Vaping industry. These are the ones who will be impacted the most by the policies so we should keep them in mind when designing policy and not let Juul and their lobbyists write the legislation, in response to Juuls own bad behaviour (as always seems to happen), so we only end up with Juul type big companies.
