E-cigarette manufacturers insist that their products are much less harmful than cigarettes. However, this is not necessarily the case and depends on the substances in the vapor. JUUL pods can contain toxic chemicals, such as formaldehyde, in addition to nicotine. These chemicals could cause lung damage and health issues.
According to Johns Hopkins Medicine, vaping may be less harmful than smoking ordinary cigarettes, although vaping is not considered safe. The Centers for Disease Control and Prevention (CDC) discourages non-smokers who think e-cigarettes are safer from using them. The agency further states that e-cigarettes may be unsafe for young adults, pregnant women, and others who do not smoke. However, the real dangers of e-cigarettes or vape pens are not yet fully understood, and research is still ongoing.
