Are e-cigarettes a safe alternative to cigarettes? Could they help millions of smokers quit smoking? If so, why would anti-tobacco activists oppose e-cigarettes? Get the truth about e-cigarettes in this short video.

Disclaimer: This video is about the relative benefits of legal e-cigarettes vs. smoking tobacco cigarettes. A cottage industry of unregulated, illegal and potentially dangerous products containing THC (the active ingredient in marijuana) has emerged, giving rise to alarming headlines about vaping causing potentially fatal lung disease. Virtually all such cases involve use of gray-market THC-laced liquids. PragerU's view, based on the available evidence, is that e-cigarettes are safer than tobacco cigarettes and can help people quit smoking. Ideally, we'd prefer you use neither, but if you choose to use e-cigarettes, we encourage you to use only legal products sold by reputable retailers.
