First of all, make sure that you are using the correct strength of filter. The Strong 20mg (2.0% per ml) is our most popular nicotine strength.
Taking quick puffs will be less effective and nicotine will not readily absorb. Each inhale should be slow, steady and last for a minimum of 2 seconds. Hold the vapour back for a couple of seconds before slowly exhaling. Taking a longer inhale of around 5 to 6 seconds will help deliver a stronger nicotine hit.
