It is easy to grow your own tobacco. Cure it by hanging mature plants in a shed or somewhere they won’t be disturbed. You can use it as chew as soon as it is dry, but the flavor improves with age. Store it in mason jars when they have cured to a point you like. It will keep for many years and only improve. I use a very small amount, about 1 sq mm, for chew a few times a day. I add nothing to it, just a plain small piece of a leaf. Nicorette tablets are also good. One 2mg tablet can be used and reused a few times during the day. You do not need very much to get the benefit. ABN
