The Centers for Disease Control and Prevention (CDC) warns that e-cigarettes may be an emerging public health issue. More research is needed to understand the health impacts of e-cigarettes, but studies have found cancer-causing and toxic chemicals in the first and secondhand vapor. The CDC reports a sharp rise in the number of calls to U.S. Poison Control Center concerning children being poisoned by liquid nicotine. Without state or federal marketing restrictions, with the delay in setting age restrictions, and with flavors like gummy bear and Girl Scout cookie, more than five times as many youth in Lane County used e-cigarettes in 2015 than in 2013.
