What to do about inhaling/breathing when smoking/vaping?

Can't help but: Wonder if you think you can't walk and chew gum at the same time. When people either smoke or use e-cigarettes or hookahs, they are breathing just fine, despite taking in carbon monoxide, formaldehyde and other toxins. While e-cigs may be somewhat safer, we really don't know their long-term effects, or what the oils, flavorings, additives and propylene glycol actually does to our body.Try stopping.
