high off of no battery

Its currently the school year, and my friends smoke, however i dont want smoke or snything because we get randomly drug tested. i hit my friends cartridge pen without a battery, i hit it for like 10 seconds, as previously no battery no wire, nothing but air. i feel high about 30 minutes later, and i could taste the weed and smell it on my breath after. im scared that im gona test positive for weed if drug tested this monday. any help?
