It looks like Seattle and Portland.

KING COUNTY, Wash. — Lurking inside countless King County Metro Transit buses and trains is growing frustration over dangerous fumes from America’s deadliest drug.
According to several Metro Transit drivers and the union representing thousands more, blue counterfeit M-30 oxycodone pills — commonly laced with fentanyl — are openly smoked or “freebased” by riders aboard buses and trains, exposing riders and operators to fumes often described as “sickening.”

How could one get indirectly exposed to fentanyl from another person? Could you absorb it through the skin? Or through the air?
The risks are very low. When someone smokes fentanyl, most of the drug has been filtered out by the user before there is secondhand smoke. It doesn’t just sort of float around. Studies have looked at fentanyl concentrations in the bloodstream after someone has had secondhand fentanyl exposure from smoke. The levels are extremely low or not detectable. So, there’s no real risk for the everyday person being exposed to secondhand opioid smoke.
So the lesson from this is ride the bus, don't worry about the people smoking fentanyl, it won't hurt you, don't worry what the bus drivers say. Oh and the people that smoke it are not being guided off the bus, not being kicked off the bus. No, because you can't do that. And no one will prosecute it except they will prosecute the driver that kicks them off the bus or anyone else that does so.
That's what it looks like.
