I recently read an article about the study in Germany conducted to 22 people to know if ecigs are safe to human's health and found out that the device actually is beneficial compared to tobacco cigarettes and do not harm the heart. Well in the article too it was honestly said that the study conducted was done in a very few subjects only and in a very short time to conclude that ecigs are 100% safe to use. However, this is still a good news right? I hope that continuous study about this alternative to smoking will soon give light and for everybody's peace of mind.
