Questions we are asked about TPD compliance

Is Vape Sourcing e-liquid suitable for someone switching from cigarettes?

It can be, and it is one of the more common routes. The deciding factors are the draw style and the strength: a tighter draw with a mid strength is what most switchers settle on, and staff who ask what the customer currently smokes tend to get the match right first time.

What strength should a retailer stock first for Vape Sourcing e-liquid?

Start with the middle strength in the range and add one step either side once you see what sells. Shops that open with a single strength almost always have to reorder within a fortnight, and the second order is usually the one that reveals the real demand curve.

What causes a burnt taste with Vape Sourcing e-liquid?

Nine times out of ten it is priming. A coil that has not been saturated before first use, or a tank run dry, will scorch the wicking and that taste does not go away. Fitting a new coil and waiting a few minutes before the first draw prevents it entirely.

How long does a unit of Vape Sourcing e-liquid last in normal use?

For a typical adult user the answer sits between 21 and 29 days, depending on draw length and power setting. Heavy users will be at the short end of that range, which is worth knowing when you plan reorder volumes.
