Using the details in this section to narrow the range down to the top 3 locations to buy medicinal marijuana.
And now that you've completed the necessary work, it's time to finally check the list of top pot stores and clinics. There's no greater analysis than your own first-hand experience so you'll need to try out these sites by yourself to really know which source is correct for you.

All it suggests for you is that any single doctor or pharmacy you visit should be a new encounter.
