Cannabis has been a medicine for far longer than it has been a drug. There are many different theories of its history, and signs of it date back to the old testament and ancient europe, all over Asia, and spread down into Africa. Ancient history is a matter of interpretation and the details remain in debate, but cannabis use was a huge part of culture and medicine in distant parts of the world. As a medical user, I do still get high some times for fun. But that's not the whole picture.
