Smart Smoker Polyethylene Glycol, PEG-400.

Possibly the ideal mixture for diluting nicotine based e liquids.

The 400 only relates to its molecular weight, but we think it sounds impressive, not to be confused with Ethylene Glycol which is poisonous, PEG is fully approved for pharmaceutical use and in fact can be found in many mouthwashes and foods.

Ideal for the odd person who has an allergy to Propylene Glycol.

Available in 4 sizes.
