Another word for a breathalyzer, which is a device used to monitor one's blood alcohol content (BAC). Dubbed 'the Lahey juul' because in the television series "Trailer Park Boys," Jim Lahey (park supervisor) frequently uses a breathalyzer in a similar fashion to a nicotine addict.

Yo I got pulled over by this cop who was super chill. He even let me hit his Lahey juul.

Juul

A highly concentrated nicotine vaporizer which underage kids use to get a buzz. It is commonly mistaken for a USB stick which makes it easy to take use in class. A rip from this device is usually referred to as a 'wop' and the stick itself is also known as a wop machine. High school age kids often ask to use the bathroom, but instead they are getting nic rpped in the bathroom off of wops.

Student: Hey teacher can I drop a log in the bathroom right quick?
Teacher: Yeah get your shitty smellin ass outta my classroom.
Student gets into bathroom and immediately starts takin mad wops from his USB lookin ass Juul.
