DWHigh

Taken from its paralleled alcohol counterpart the DWI, a DWHigh is a driving-related offense due to excess levels of marijuana in the driver's system. Although weed does not impair driving abilities as drastically as alcohol, some people still can't handle it and get pulled over, whereupon the officer realizes the driver is high as shit and arrests him for a DWHigh.

Passenger: Dude, why are you going 15 MPH in a 35?

Driver: I'm high as a kangaroo on a trampoline yo, I feel like I'm going 60.

Passenger: Well you better calm the fuck down and speed up else you could get pulled over for a DWHigh.
