Early Use of Cannabis in Canada

Cannabis and hemp have a rich history of use in Canada that dates back centuries, long before there was any thought of cannabis prohibition in Canada. This section explores the early uses of these plants, highlighting their significance in Indigenous cultures, their medicinal applications, and their industrial benefits.

Indigenous Use of Hemp

Long before European settlers arrived, Indigenous peoples in Canada were already utilizing hemp for its versatile properties. Hemp fibers were solid and durable, making them ideal for crafting essential items such as ropes, fishing nets, and clothing. These materials were integral to daily life, helping with tasks ranging from fishing and hunting to creating shelters and tools. Hemp’s resilience and adaptability to various climates make it a valuable resource for Indigenous communities across different regions of Canada.

For example, the Haudenosaunee (Iroquois) are known to have used hemp fibers extensively. The plant was woven into ropes and nets essential for their fishing practices. Similarly, hemp created strong and reliable bowstrings, showcasing its importance in hunting and warfare.

Early Medicinal Use

In the early 20th century, cannabis was widely recognized for its medicinal properties. At a time when modern pharmaceuticals were still in their infancy, cannabis was a common ingredient in a variety of tinctures, tonics, and remedies. These preparations treated various ailments, including pain, inflammation, digestive issues, and insomnia.

Physicians of the era often prescribed cannabis-based medicines for conditions like rheumatism, epilepsy, and menstrual cramps. For instance, a popular product of the time was “Cannabis Indica” tincture, which was used to alleviate pain and induce relaxation. This practice was not unique to Canada but was part of a broader trend in Western medicine, where cannabis was a standard component of pharmacopeias in Europe and North America.

Industrial Uses of Hemp

Hemp was also highly valued for its industrial applications. The plant’s robust fibers produced textiles, paper, and even early plastics. Its versatility made it an essential crop for settlers and early Canadian industries.

One notable example of hemp’s industrial use is producing sailcloth and rigging ship ropes. Hemp was favored in maritime industries because of its strength and resistance to saltwater. This made it critical material for the British Royal Navy and, subsequently, for Canadian maritime activities, aiding in commercial and military endeavors.

Additionally, hemp was used to manufacture durable paper products. Before the advent of wood-pulp paper, hemp fibers were a primary source for making high-quality paper. Historical documents, including early drafts of significant legal texts, were often written on hemp paper due to its longevity and durability.

Economic Importance

Economically, hemp and cannabis cultivation provided substantial benefits to early Canadian farmers. The crop was relatively easy to grow and could thrive in Canada’s diverse climates, from the fertile plains to the coastal regions. Hemp’s quick growth cycle allowed for multiple harvests annually, contributing to its economic viability.

Farmers often rotate hemp with other crops to maintain soil health and reduce pest infestations. The hemp plant’s deep roots helped prevent soil erosion and promoted nutrient cycling, making it a beneficial addition to crop rotation systems.

Cultural and Social Significance

The use of cannabis and hemp also carried cultural and social significance. In many communities, the plant was integrated into traditional practices and rituals. For example, hemp’s fibers and seeds were often used in ceremonial garments and objects, symbolizing strength and resilience.

Furthermore, the medicinal and industrial use of cannabis and hemp played a role in community bonding. Sharing remedies and collaborating on hemp-based projects fostered a sense of cooperation and mutual support among early Canadian settlers and Indigenous communities.

The Beginnings of Cannabis Prohibition in Canada

Due to a combination of moral panic and racial prejudice, cannabis prohibition in Canada began in the early 20th century. The 1920s saw the rise of prohibitionist attitudes toward various substances. Influential figures like Emily Murphy, whose writings were filled with alarmist and xenophobic rhetoric, contributed to the growing fear of cannabis. In 1923, cannabis was added to the Opium and Narcotic Drug Act without significant debate, marking the beginning of its criminalization.

The Impact of Cannabis Prohibition in Canada on Society

The criminalization of cannabis had far-reaching effects on Canadian society. Individuals caught with cannabis faced severe legal consequences, including imprisonment. These laws disproportionately affected marginalized communities, exacerbating racial and socio-economic disparities. The stigma surrounding cannabis use grew, painting users as deviants and criminals, which further fueled public support for strict enforcement.

The Counterculture Movement and Cannabis

The 1960s and 1970s brought a wave of cultural change, including the counterculture movement, which embraced cannabis as a symbol of rebellion and freedom. Recreational use of cannabis surged, particularly among youth. This shift in public behavior prompted the government to ramp up law enforcement efforts, even as societal attitudes began to soften and more people questioned the harsh penalties associated with cannabis use.

The Le Dain Commission

In 1969, the Canadian government established the Le Dain Commission to study the non-medical use of drugs. The commission’s extensive research and public hearings led to a groundbreaking report that recommended the decriminalization of cannabis possession. However, despite the evidence and strong recommendations, the government largely ignored the report, continuing to enforce cannabis prohibition in Canada.

The War on Drugs

The 1980s and 1990s saw the escalation of the War on Drugs, both in Canada and globally. Increased police powers, harsher sentencing laws, and a zero-tolerance approach to drug enforcement marked this period. Cannabis remained a vital target of these efforts, with significant resources dedicated to eradicating its use and distribution. The societal impact was profound, leading to a surge in cannabis-related arrests and further entrenching the criminal stigma.

The Path to Medical Cannabis

Despite the harsh climate of the War on Drugs, advocacy for medical cannabis use gained momentum. Key legal battles, such as the R. v. Parker case in 2000, highlighted the necessity of cannabis for certain patients. This led to the introduction of the Marihuana Medical Access Regulations (MMAR) in 2001, which allowed patients to legally access cannabis for medical purposes, marking a significant shift in public and legal attitudes.

The Road to Legalization

The 2015 federal election marked a turning point for cannabis in Canada, with Justin Trudeau’s Liberal Party promising to legalize recreational use of the drug. After years of planning and consultation, the Cannabis Act was enacted, and on October 17, 2018, Canada became the second country in the world to legalize recreational cannabis. This monumental change aimed to regulate the industry, eliminate the black market, and protect public health.

Post-Legalization Landscape

Since legalization, Canada’s cannabis landscape has undergone significant transformation. Public perception of cannabis has continued to evolve, with increasing acceptance and normalization of its use. The legal cannabis industry has contributed substantially to the economy, creating jobs and generating tax revenue. However, challenges remain, such as addressing the remaining black market, ensuring product safety, and navigating the complex regulatory framework.

Reflections and Future Directions

The history of cannabis prohibition in Canada offers valuable lessons for future policy development. Understanding the socio-political factors that drove cannabis prohibition in Canada helps address current issues more effectively. As debates continue around cannabis regulation, there is potential for further reforms, including expunging past convictions and enhancing accessibility for medical users. Canada’s approach to legalization also serves as a model for other countries considering similar measures.


The journey from cannabis prohibition in Canada to legalization in Canada is a testament to the changing tides of public opinion and political will. While significant progress has been made, ongoing efforts are required to address the remaining challenges. By reflecting on the past and learning from it, Canada can continue to lead the way in creating a fair and effective cannabis policy that benefits all its citizens.
