In my opinion there is no worry to have in this regard
Simply the question is, why in France, for example, health authorities call for greater caution on
ecig
Never on cigarettes real, it has been said about danger of PG when it is burnt
The only indication that exists on a packet of cigarettes are the rate of "goudron"(for example, it's material on the road) and nicotine levels
According to Professor Molimard, it is ridiculous!
Because it is not notified the rate of nitrosamine, which is highly cancérigéne (tumeur, carcinome..in french)
For the level of nicotine, the human body arranges to take the quantity needed whatever the rate content in cigarettes
and it's not problem ! The problem is not the quantity of cigarettes smoking but the during you smoke along your life
While it looks rather an organized attack multinational pharmaceutical companies or
tobacco
Excuse me for English write but my english is so poor !
