E-cigarettes
While components of the technology have existed for decades, the first modern e-cigarette was introduced in 2006. Since then, the devices have become wildly popular as an alternative to traditional cigarettes, and new trends, such as the use of flavored juice, have contributed to the success of companies like Juul.
Recent studies have shown that there remains a great deal of uncertainty and risk surrounding the devices, with an increasing number of deaths and injuries linked to vaping. In early 2020, the FDA issued a widespread ban on many flavors of cartridge-based e-cigarettes, in part because those flavors are especially popular with children and younger adults.
