Hit, PG, VG : quèsaco ?

In France and elsewhere, vape has its own vocabulary. It is sometimes difficult for a new vaper to understand. Find here a short definition for
hit, PG and VG.

The word “hit” refers to the sensation at the moment the pharynx contracts in contact with the nicotine and propylene glycol when aspiring e-cigarette vapour or cigarette smoke. It is the effect desired when an ex-smoker vapes. The “hit” is inseparable from the pleasure obtained through the inhalation.


The PG/VG content is the percentage of propylene glycol (PG) and vegetable glycerin (VG) present in an e-liquid or a base. This mixture acts as a support diluting the aromas and the nicotine.

A high PG content favours the hit, while the vegetable glycerin provides a slightly sweet flavour and favours the production of vapour. The ideal is to find a balance between the two.
