According to the CDC, as of January 2020, there have been 60 deaths due to lung injuries caused by the use of e-cigarettes and vaping devices. While vaping-related injuries are more likely to occur when either the device or the e-liquid has been modified, they are also more prevalent when the liquid being vaporized contains THC. It’s true that here are fewer chemicals in e-cigarettes than in traditional tobacco products, but that does not make vaping safe.
The truth is that vaping is every bit as addictive as smoking cigarettes. Nicotine, which is the addictive component, can be inhaled through e-cigarettes in higher concentrations than traditional tobacco products. In addition to the risk of chronic lung conditions and cardiovascular diseases that often arise from any kind of smoking, there is an unknown factor involving chemicals in the liquid that are not yet understood, but probably unsafe.
