Cannabis Activism in Canada During the 1910s

The short answer: there wasn't any

No credible primary source documents an organized cannabis-related political movement in Canada during the 1910s — for or against the plant. Cannabis was not a subject of parliamentary debate, newspaper campaigns, temperance-society resolutions, or medical-society petitions in that decade. Strong evidence

The drug-policy conversation in 1910s Canada was almost entirely about opium, and secondarily about cocaine and morphine. The foundational Canadian drug law of the era, the Opium Act of 1908, was drafted by Mackenzie King following anti-Asian riots in Vancouver and targeted the opium trade specifically ^[1][2]. It said nothing about cannabis. Its 1911 successor, the Opium and Drug Act, added cocaine, morphine, and eucaine — but again, not cannabis ^[3].

Why cannabis wasn't on anyone's radar

Three practical reasons cannabis generated no activism in 1910s Canada:

1. It wasn't widely used recreationally. Recreational cannabis use in North America was concentrated in specific communities — parts of the U.S. Gulf Coast, Mexican migrant labor networks, and certain Caribbean populations — none of which had significant presence in Canada in the 1910s ^[4]. There was no user population to organize and no visible 'problem' to mobilize against.

2. Medical cannabis was a minor pharmacy item. Cannabis tinctures and extracts (Cannabis indica) appeared in Canadian and British pharmacopoeias as one of many botanical remedies, used for pain, sleep, and menstrual complaints. It was legal, uncontroversial, and unremarkable — sold by pharmacists alongside dozens of other plant extracts ^[5]. Nobody campaigned to restrict it because nobody was alarmed by it.

3. Industrial hemp was not politically salient. Hemp had been grown in Canada since the 1600s under French and later British encouragement, mostly for rope and cordage, but by the 1910s the industry had largely collapsed under competition from Manila hemp and other fibers. There was no organized hemp lobby to speak of ^[6].

What came next: the 1923 addition with no debate

The most notable fact about early Canadian cannabis prohibition is how quietly it happened. In 1923, Parliament passed An Act to Prohibit the Improper Use of Opium and Other Drugs, which added cannabis ("Cannabis indica (Indian hemp) or Hasheesh") to the schedule of prohibited drugs ^[7].

Historian Catharine Carstairs, who has done the most careful archival work on this period, found no recorded parliamentary debate on the cannabis addition. It was inserted into the schedule with no explanatory statement, no medical testimony, no public campaign, and no press coverage of note ^[8]. This makes Canada one of the earliest countries to prohibit cannabis at the federal level — years before the U.S. Marihuana Tax Act of 1937 — and it did so essentially by clerical addition.

The popular story that Emily Murphy's 1922 book The Black Candle drove cannabis prohibition is overstated. Disputed Murphy did include a lurid chapter on 'marahuana' [sic], drawing heavily on sensationalist U.S. sources, but Carstairs and other historians have found little evidence that this chapter directly caused the 1923 scheduling decision — Murphy's influence on the broader drug-panic climate is real, but the specific mechanism connecting her writing to the cannabis clause is not well documented ^[8][9].

Myths to watch out for

A few claims circulate online that don't hold up:

• "Canadian hemp farmers organized against early prohibition." No primary source supports this. The Canadian hemp industry was already moribund by the 1910s. No data
• "Emily Murphy single-handedly caused Canadian cannabis prohibition." Overstated. Her book contributed to a moral climate, but the actual 1923 legislative act has no documented causal link to her lobbying. Disputed
• "There were Canadian cannabis-legalization advocates in the 1910s." No. Organized Canadian cannabis reform advocacy is a phenomenon of the 1960s onward, associated with groups like the Le Dain Commission era and later NORML Canada. Strong evidence
• "Cannabis was a major concern of the temperance movement." No. Canadian temperance in the 1910s was overwhelmingly focused on alcohol, secondarily on opium. Strong evidence

How to research this period yourself

If you want to verify any of this, the useful primary and secondary sources are:

• The Statutes of Canada for 1908, 1911, and 1923, available through the Library of Parliament and provincial law libraries.
• Catharine Carstairs, Jailed for Possession: Illegal Drug Use, Regulation, and Power in Canada, 1920–1961 (University of Toronto Press, 2006) — the standard academic history.
• The Le Dain Commission's Interim Report (1970), which contains a historical overview of Canadian drug law based on archival research done closer to the source.
• Digitized Canadian newspapers via the Toronto Public Library and Library and Archives Canada — a search of the 1910s yields essentially zero cannabis-related political coverage, which is itself the finding.
