Has any doctor found negative effects from e-cigarettes?

Start researching: I checked a few Medscape articles and e cigs are not without risk. Some e cigarettes deliver dangerous chemicals and carcinogens and sometimes the nicotine on the label is not the correct amount. Basically it is unregulated. Also lots of little kids are eating them by accident leading to an increase in Poison control calls. It is better not to Vape if possible
