Stevon Williams says he is proud of his job as a bus driver for King County Metro, but he says fentanyl smoke is now so common that it's making him sick.

“I really hadn’t ever heard of fentanyl smoking on the bus when I was hired by Metro," Williams told KOMO News. "I don’t want to be put in a predicament where I’m around drugs every day on my job - I didn’t sign up for that.”
