What if someone is so stoned that they can transmit their high through very close contact?

It's why it's great to get stoned with a friend and get a feedback loop going

Second hand smoke you mean? Lol

I think that's called a contact high.

That’s basically a running joke at my job about one of the bakers on the morning shift. Guy was a meth-head/dealer. Talks so fast and never shuts up that you’d start to wonder if you’re at risk of a contact high standing too close to him.

Yeah, like they breathe out gross alcohol vapor. They better go home or stay away from strangers.

Oh like, mass (collective) hysteria

Oh, if only...

Sounds about right.
