Electronic cigarettes were among the most popular electronic cigarettes on the market before the explosion at a tobacco factory in the Netherlands last week.
The company that makes the devices has said that it is taking steps that will improve the safety of the devices.
In a statement to the AP, the company said it is working with the Dutch government to identify and improve the quality of its products and the safety measures it has put in place.
It also said that a third of its e-cigarettes are sold in the U.S. to consumers who are not currently using them.
In addition, e-cig makers have reported more than $3 billion in revenue this year, according to research firm Euromonitor.
They are also trying to increase their profits.
The Dutch government is investigating the explosion.
The explosion occurred at the Smutkonten Tobacco factory, located near the southern city of Maastricht.
According to Reuters, the explosion occurred shortly after the company had started producing a new generation of the popular electronic cigarette, known as an e-liquid, in May.
