A brief history
The use of cannabis was believed to originate in Central Asia. Its documentation dates back to 2800BC. In 1841, Irish physician Sir William O’Shaughnessy introduced cannabis to Western medicine. Following this, cannabis was used as medicine and made into tinctures, pills and other products. By the early 20th century, cannabis became illegal in many parts of the world and has only recently become legalised in many countries for medicinal use.
