FDA Is Investigating Seizures Linked to E-Cigarettes Since the Food and Drug Administration (FDA) announced the probe in April, the number of investigated cases has expanded by almost 100. The 127 cases occurred between 2010 and 2019. They included instances of fainting and other episodes possibly related to seizures. Outgoing FDA Commissioner Scott Gottlieb has been outspoken on the possible dangers of e-cigarettes, referring to teen vaping as an "epidemic." Through an online portal, the FDA is encouraging the public to come forward with "unexpected health or product issues.” Ned Sharpless, FDA Commissioner, via Gizmodo Gottlieb called the uptick in reported cases of seizures possibly linked to vaping "concerning."
