Now, for your listening pleasure … an on-air asphyxiation.

That’s the premise of a radio spot commissioned by Drug Free Pennsylvania, a Harrisburg-based nonprofit organization. Targeting teenagers, the ad focuses on “huffing,” or the use of inhalants, like glue or spray paint, to get a cheap but potentially lethal high.

In the stark 30-second spot, listeners hear only the sound of an aerosol can being sprayed, followed by a huffer taking two deep breaths. On the third breath, the huffer suddenly gasps for air. The next sound is the aerosol can dropping ominously to the floor and rolling to a stop.

Finally, a voiceover warns about the dangers of huffing, which can kill thrill seekers the first time they try it.

“Huffing is now the third most common way kids get high, and it’s dangerous,” said Beth Winters, executive director and general counsel of Drug Free Pennsyl-vania. “We want anyone who may try huffing and their families to understand this isn’t some adolescent lark. It can kill you.”

The radio spot, created by the Barry Group, a full-service agency in York, Pa., began airing earlier this month on Pennsylvania stations. Jon Didier
