question 1 of 5
vaping is...
...the act of inhaling and exhaling non - toxic smoke from a device like a cigarette.
...the act of inhaling and exhaling vapor from a cigarette or other combustible product.
...the act of inhaling and exhaling water vapor that is free of toxins.
...the act of inhaling and exhaling the vapor from a device like an e - cigarette or vape pen.

Explanation:

Vaping involves using devices like e - cigarettes or vape pens. The vapor from these devices (not traditional cigarettes which involve combustion) is inhaled and exhaled. Option 1 is incorrect as the vapor from vaping devices may not be completely non - toxic. Option 2 is wrong because vaping is not about inhaling from a traditional combustible cigarette. Option 3 is incorrect as it's not just water vapor (e - liquid usually contains propylene glycol, vegetable glycerin, flavorings etc.).

Answer:

...the act of inhaling and exhaling the vapor from a device like an e - cigarette or vape pen.
