As of January 2015, there are 23 states and districts in the US that have enacted laws to legalize medical marijuana. As the state count continues to grow, health professionals are discovering even more ways marijuana can effectively treat many medical conditions.

But the therapeutic use of cannabis is not a novel idea. The practice actually dates back nearly 5000 years when Chinese and Indian cultures first recognized the plant’s medicinal properties. Cannabis didn’t even make it over to the US until the 1700s in the form of hemp. And it wasn’t until the mid-1800s that marijuana actually became mainstream medicine throughout the west.

Below is a brief timeline of the history of medical marijuana and its journey to the United States. From its ancient beginnings to its innovative application today, cannabis spans centuries of invaluable medical use.
