Almost as soon as the e-cigarette maker Juul launched in the Philippines this past June, Maria Encarnita Limpin started noticing the product in shops all over the capital Manila.
"It's like they mushroomed," she says.
Limpin is a doctor specializing in lung disease and also directs a nonprofit that has helped push though rules preventing the marketing and sale of cigarettes to minors in the Philippines. So she was particularly horrified to see how visible Juul's vaporizers are in areas where children are likely to see them.
