My thoughts are this.....once you say 10 or 100 coins per gram, you can never change it to 1 coin per gram. If you have enough disperseries agree to sell for 1 gram = 1 coin, and set a strict limit of 1 or 2 grams per customer at first (I suppose that could be increased as time goes on), then 1 coin could be 1 gram and it would not wipe out inventories, although there would probably be lines at the participating dispenseries which of course would be amazing PR.
Just my thoughts.
