Running a b-route is to drive a car for the purpose of somewhere to smoke. The origins of this term are unknown, but one can assume that b is short for "burn a bowl". This term is very useful to use in the company of non-smokers.
"Hey, wanna run a b-route and try out my new piece?"

"Hey, pigs round here, we should take this b-route somewhere else."
