at my new scary bus

at my new scary bus stop, there's some graffiti on the station. my favorite is some words that are spray-painted into the steps coming down from the platform. they're all in the same handwriting and in the same color, so i'm assuming it was the same person. on the first landing it says "reefer" on the next it says "crack cocaine" and on a step right by the bottom it says "go bowling"

is the implication that these drugs are taking over our inner city, and the solution is to go bowling? or that bowling itself is more addictive than crack?
