I think that the 30% potential market is even greater than that in reality, because this doesn't take into account the private businesses that would also show interest in it.
Good point! Imagine all the bio-shops, and groceries that are going to use it!
Not only that, what about all the restaurants, fast food joints, and even coffee shops(wherever its legal).
Also the 30% of bio food eaters, doesn't take into account all the shit food eaters who would love the idea having their own weed.
