The flavour of the herb will be affected by the herb’s consistency more than the kind of vaporizer that is used in vaping The grinder cards ensures that the herb has been evenly grounded thus allowing it to burn even more consistently. This is what will result in a continuous flow of flavoured vapours.

Thick Vapours
