If you think you are doing well now, just wait. There are new compounds being developed all the time and I am hearing some of the curative properties are profound. I remember when the patch was talked about, and Dalton claimed it would be a "platform" that will be used to administer dozens of medications to treat some of the biggest ailments of our time.
The interesting thing about these new cannabis medications is that they are all natural, and that may mean shops like yours could become a semi-drug store. The difference is that in almost all cases a prescription will not be required.
