Now scared to know what the make of the cigarette only by the word "Resin" is a huge list of chemicals. and in the composition of the liquid for electronic cigarettes is fine, especially if it without nicotine.
The advantages of electronic cigarettes :
- Pleasant smell
- No debris from cigarette butts and packs of cigarettes

Generally my position in life that all you can afford and do not harm the body if not to abuse
