The cannabis plant has a long and complicated history, being both honoured in herbal medicine and religious ceremonies — and outlawed as an illegal substance. This three-part series explores the lows and highs on the long journey toward cannabis legalization in Canada.
Neolithic period (about 10,000 BCE)
Cannabis and Hemp Grow Organically
Cannabis is indigenous to central and southern Asia, where hemp (a similar plant with less THC) is cultivated for fibre and food.
Cannabis Is Used for Medicine and Recreation in Central Asia and China
In central Asia and China, cannabis is used as herbal medicine and to make paper and cloth. Almost 1,300 years later (around 700 BCE), the Scythians (Iranian nomads in central Asia) use cannabis recreationally, inhaling the smoke from smouldering seeds and flowers to produce a high.
Roman Texts Cite Cannabis as Cure for Illnesses and Ailments
Pliny the Elder, a Roman scientist and historian, writes, “The roots boiled in water ease cramped joints, gout too and similar violent pain.” By 800 CE, hashish (cannabis resin) is widely used in religious ceremonies throughout India, the Middle East and parts of Asia.
Explorers Bring Cannabis to Canada, Used for Textiles and Rope
European colonists transport the cannabis plant across the ocean to the Americas. In Europe and in Canada, hemp is grown for textiles and rope, and is an especially strong material for making sails; the seeds are used as food and oil.
Hemp Becomes Country’s Crop, Government Promotes Industry
While the first hemp crop in Canada was planted in Port Royal (now Nova Scotia) in 1606 — by an apothecary accompanying French colonist Samuel de Champlain — the Canadian government begins promoting hemp by distributing seeds to farmers to stimulate the industry.
1830s to 1900s
Cannabis Medicines Inundate Apothecaries and Doctors’ Offices in Europe, the U.S. and Canada
About 2,000 cannabis liquid extracts and resins are commonly sold in pharmacies and prescribed by doctors’ offices in Europe, the U.S. and Canada. Some of these unregulated medications are dangerous and sport outrageous claims, such as offering protection against cholera and treating rabies. In 1833, William Brooke O’Shaughnessy, an Irish doctor working in India, touts cannabis as a useful sedative and an anti-convulsive that reduces rheumatoid pain and treats nausea.
