Like many teens around the world, Queens high schooler Ninjaboy (an alias, obviously) became addicted after his first try. Most wouldn’t expect it from him, as his small frame and good-humored grin are too innocent for something like this. But his classmate persuaded him anyway, and Ninjaboy was intrigued. He had just travelled through a dank train tunnel, hopped the third rail, and slinked past MTA workers only to be stunned by the sight before him. It was the abandoned Canal Street subway station, forbidden to all but now his own to adore. The graffiti-lined walls and dim lighting widened his eyes and stirred his imagination. It was an instant high, “an adrenaline rush” as he describes it.
