Bus shut down due to fentanyl smoke

Last night I was riding the E line (I know, I know) from the Kraken game home to Shoreline, which was mostly uneventful. But at around 150th the driver stopped and made an announcement that “this bus is going out of service due to fentanyl” and made everyone disboard. I definitely smelled it (burnt rubber-y?) right before that, but would have honestly just covered my nose and put up with it since we were so close to home. Luckily I was able to call a friend who happens to live right there and drove me the rest of the way, because the next bus was 28 minutes away.

Has anyone experienced this on other routes? I’ve seen people nodding off or smelled smoke before but never had the bus shut down. I guess this kind of thing is unsurprising for the E line at night, but it sucks to have to worry about it at all.

edit: don’t want to imply I’m blaming the driver for making everyone get off the bus. He also sounded very much over it, lol.
