Emergency rooms are beginning to see serious cases of respiratory failure in young people and they are attributing it to vaping. It's really the tip of the iceberg. The use of electronic cigarettes has skyrocketed these past few years and the effect on our health is unknown. What you can surmise, with a bit of common sense, is that vaping is not going to be good for your health. It's only a matter of how bad will it be.
Vaping is like putting an unknown liquid into your gas tank and thinking the engine will run better. Lungs want fresh air. Period.
If you are vaping, the best thing to do is quit, completely, right now. Don't look back. If you need help call 415-488-0201.
