First Vaping, Now "Dripping"

A study by researchers at Yale University reveals that about a quarter of all Connecticut teenagers who have tried vaping have circumvented e-cigarettes' design to deliver a stronger and more potent nicotine experience.  It's called "dripping"; instead of allowing the e-cigarette's wick to deliver a controlled amount of liquid to the cigarette's coils, the coil is exposed so that nicotine liquid can be dripped directly onto the hot coils, producing a much heavier nicotine vapor cloud.

Regulators aren't sure how to respond to this recent trend.  Although e-cigarettes certainly aren't as harmful as cigarettes, their long-term harm (if any) is still not known simply because they haven't been around long enough.  The concept of e-cigarettes has been around since the 1930s, but the first commercially successful product wasn't created until 2003.  For a complete timeline of the development and regulation of e-cigarettes, see this file.  I can't confirm or deny the accuracy of the timeline, but the file was compiled by a group called Consumer Advocates for Smoke-Free Alternatives Association, so please be aware of possible bias.
