Can you get medical marijuana where you live? It's pretty easy here. There are stores that sell it all over the place. At the marijuana store, they refer you to a doctor who will write you a prescription. They will also give you a list of acceptable complaints that marijuana can be prescribed for.
Once you've been to the doctor and gotten your prescription, they can legally sell you marijuana. You can smoke some of it on the way home if you want.
If there aren't any stores that sell medical marijuana near you, there probably will be soon. You might even want to think about opening one. Easy work. Good money. You'll be providing a community service. Like a policeman, a school teacher or a priest.
