A US ban of the firm's products is being fought by the firm.
The FDA said in June that it would bar the sale of the products due to insufficient data. The company is appealing the decision.
Private lawsuits brought by individual families and others continue to be faced by it.
The terms of Tuesday's settlement were in line with the company's marketing practices since the fall of 2019.
"We believe that once the FDA does a complete review of all of the science and evidence presented, as required by law, and without political interference, we should receive marketing authorization."
Teens were blamed for the rapid growth of teen e-liquids. According to a federal survey, more than 25% of high school students used e-cigarettes in 2019.
According to the Connecticut attorney general, the investigation found that the company had marketed its products to children even though it was illegal in the US.
He said that the company used age verification practices that were not effective and that it did not tell the public that it had nicotine in it.
He said that Juul's advertising campaigns created a new generation of nicotine addiction.
The money from the settlement will be used to fight tobacco use.
