With medical marijuana laws being more prevalent than ever, it’s easy to forget that most marijuana users – including those who use it medically – must get their cannabis on the black market. But someday, all adults will be able to buy it in a manner similar to the one in the video below (in Colorado), although some things will vary from business to business.

The point is, most marijuana users have never been in a dispensary, but 20 years ago most people had never seen a cell phone. Twenty years in the future, buying marijuana should at least be as easy as buying a cell phone is now, for everyone.
