Vape Pens are increasingly popular among medical marijuana patients and others because they provide a discreet way to smoke cannabis.
How safe are vape pens and the liquid inside?
Who knows what’s actually being inhaled?
It’s generally assumed that vaping is a healthier method of inhaling marijuana smoke. Since a vaporizer heats the cannabis flower or oil concentrate without burning it, the active ingredients are inhaled but no smoke is involved. At least that’s how it’s supposed to work. But there may be a hidden downside to vape pens. They contain a battery-operated heating mechanism, which at can transform vape oil additives into carcinogens and other dangerous toxins.
Of particular concern: Propylene glycol, a widely used chemical that is mixed with cannabis or hemp oil in many vape pen cartridges. A syrupy, thinning compound, propylene glycol is also the primary ingredient in a majority of nicotine-infused e-cigarette solutions. At high temperatures, propylene glycol converts into tiny polymers that can wreak havoc on lung tissue.
