Almost 11 million Americans vape regularly, according to a study in the Annals of Internal Medicine, and a growing number of them are using their devices to vape CBD or cannabis oil.

But while they’re certainly safer than smoking traditional cigarettes, vape devices (and vape oils) aren’t without their issues. Cheap, shoddily-made products are often contaminated with heavy metals and other toxic substances, and trying to save a few dollars up front can end up costing much more over the long run.

To help you avoid these pitfalls — and get the most out of vaping, which can be a fast and effective way to treat many conditions like pain or anxiety — cannabisMD has put together a collection of accessible, informative guides so you can vape safely and confidently.
