It was a long time coming but tow states have finally legalized marijuana. Dispensaries have already opened in Denver, where people can purchase bubble hash legally. This may seem new, but marijuana has a long history.

The decision to legalize marijuana may seem controversial, but marijuana has been used for centuries. The first known marijuana users were the ancient Chinese. Emperor Fu Hsi, thought to be the founder of Chinese civilization, said that marijuana contained both yin and yang. The Chinese continued using medicinal marijuana for thousands of years though no one knows whether or "marijuana dispensaries" existed in ancient China. From there, it spread to Egypt, where it was used as a pain reliever for people with hemorrhoids. It wasn't until about 200 B.C. that marijuana turned up in the West, first showing up in Greece.

It would take another 2000 years before Jamestown settlers brought marijuana to the Americas. And most know about some of the founding fathers growing marijuana plants.

Marijuana's bad rap didn't come about until the 1900s. Controversy soon followed and politicians acted with force. The decades long war on drugs began. It wasn't until the following decades that states slowly allowed medicinal marijuana. These days, medical dispensaries can be found all over California. And then a watershed moment: Colorado and Washington completely legalized marijuana. Nowadays, bubble hash can be found all over Denver in legal dispensaries.
