Vaporizers have been around for a very long time, though the trend has taken off in the last decade or so. As the benefits of vaporization have become more understood by the masses, the variety of devices has been increasing. It seems you can’t walk down the street these days without seeing someone using the ubiquitous vape pen. These handy, low-cost devices are ideal for the on-the-go commuter or those wanting a few puffs throughout the day. Vape pens contain a concentrated oil that heats up just enough to create a thin, wispy vapor.
