Rizla Fresh Mint FLAVOR Infusion Card Disappointed by the ban on FLAVORed tobacco? Look no further than this handy FLAVOR infusion card by Rizla. Simply pop the FLAVOR card into your tobacco pouch or a packet of cigarettes, wrap it up tight and wait at least 60 minutes for the contents to infuse. You can leave it in longer for a stronger, more intense FLAVOR. The card will infuse a refreshingly mild and minty FLAVOR and aroma into up to 50g of tobacco or a packet of 20 cigarettes.
