Don't show your bodohness in public bro, quite malu. So you mean to say the vapor vapers blowing got heavy metal particles flying inside together? Try saying that out loud maybe you can realize how stupid that sounds.

The only controlled substance in an e-liquid is nicotine, which is also found in small traces on the fruits and vegetables you eat on a daily basis. The other ingredients is PG (Propylene Glycol) & VG (Vegetable Glycerin). PG and VG are widely accepted food additives regularly used in the food industry

You do know 99.9% of e-liquids on the market uses flavoring from a company called TFA (The Flavor Apprentice, https://shop.perfumersapprentice.com/t-Culinary.aspx) and Capella (https://capellaflavors.com/) which is a company that does flavoring for drinks. These flavorings are in all your soft drinks, used in baking, coffee syrup flavorings, etc. This companies main business is supplying to beverage companies.

So please before you post rubbish, try to do some research or don't post at all.

I prefer smokers to vape, at least the 2nd hand smoke not so toxic.
