They haven’t been studied enough yet for effects to be understood.
Electronic cigarettes have passed the $1 billion-a-year mark, so naturally they are catching the attention of public officials. Indiana Attorney General Greg Zoeller is calling for the FDA to regulate the product, and there are indications the General Assembly will consider regulations and restrictions.
Such scrutiny is appropriate, but caution is in order, too. E-cigarette use is steadily increasing, and the health effects of the product haven’t been studied enough for new legislation to be on the solid factual footing it should be. It would be reactionary and misguided to just regulate “vaping” the way smoking is, because they are clearly not the same thing.
