Because of the minutely small scale of our filling process, you may find some variation in the nicotine levels of our nicotine-containing products. The **expected range** of our high-strength nicotine **is skewed towards the lower end**, because of the legal maximum nicotine level already established in some countries. Since we take our responsibility seriously, we track this limit closely for each new batch of production.

J'aimerais trouver une formulation "parlante", car il s'agit ici des FAQs du site - j'aimerais donc éviter un langage de statisticien!

Merci d'avance pour vos lumières et suggestions :-)
