Almost half of the people who followed Juul Labs Inc. on Twitter last year were not old enough to legally purchase e-cigarettes in the United States, according to a study published on May 20.
Researchers analyzed data collected in April 2018 on public followers of Juul’s Twitter account (@JUULvapor) with at least one public tweet. About 45 percent of those who followed Juul were 13 to 17 years old, according to the study published online in JAMA Pediatrics.
