Green Canvas: Visual Voices in the Cannabis Struggle

By Hanna Swanepoel

Cannabis prohibition has always been a contentious issue in South Africa, deeply intertwined with the nation’s history of colonialism, apartheid, and social justice struggles. The decriminalisation of cannabis, or dagga as it’s locally known, began in the 20th century and became a tool not only of legal control but of cultural and racial oppression. Through decades of prohibition, cannabis grew into a symbol of resistance, identity, and survival.

Artists and creators have played a pivotal role in challenging cannabis prohibition, using their work as a powerful form of protest and expression. Across South Africa and beyond, the fight against cannabis bans has been amplified by striking visuals, potent symbolism, and heartfelt storytelling. From underground posters to modern street art, cannabis prohibition art tells the story of a people’s struggle for freedom, dignity, and respect.

The Roots of Cannabis Prohibition and Its Impact on South Africa

Understanding cannabis prohibition art means understanding where it came from. South Africa’s cannabis laws didn’t appear in isolation—they came hand-in-hand with the oppressive frameworks of colonial rule and apartheid; systems designed to marginalise and control the majority. Dagga was criminalised in 1928 as part of a wave of global anti-cannabis legislation influenced by racial and political motives. The plant was associated with Indigenous and rural communities, especially black South Africans, and the laws disproportionately targeted these groups, leading to mass arrests, broken families, and lost livelihoods.

The stigma that prohibition created went beyond legal punishment; it seeped into society’s perceptions, shaping how cannabis users were viewed, often unfairly as criminals or deviants. This fueled a deep cultural tension and sparked resistance in many forms, including art.

Art as Creative Resistance

In the face of harsh laws and social stigma, South African artists began to harness the power of visual culture as a tool of resistance. Art became a way to communicate defiance, hope, and solidarity, often shared in underground circles or community spaces.

One of the most iconic groups in this context was the Medu Art Ensemble, active in the 1970s and 1980s. Although their work covered many aspects of the anti-apartheid struggle, they also highlighted the criminalisation of cannabis as part of the broader system of oppression. Their posters, murals, and prints used bold colours and provocative imagery to educate and mobilise communities, embedding cannabis rights within the broader fight for freedom and justice. Operating mainly in exile, Medu’s art combined traditional African aesthetics with contemporary political messages, making them pioneers in fusing culture and activism.

Beyond Medu, anonymous graffiti and street art became a popular medium for expressing support for cannabis legalisation. Murals depicting cannabis leaves intertwined with symbols of liberation—like fists raised in solidarity started appearing in townships and city centres. These public displays were subtle acts of rebellion, reclaiming the narrative from criminalisation and celebrating cannabis as part of the nation’s heritage.

The Dagga Couple and the Visual Fight for Legalisation

Fast forward to more recent times, and one of the most well-known figures in South Africa’s cannabis legalisation story is the Dagga Couple—Julian Stobbs and Myrtle Clarke. Arrested in 2010 for cannabis possession, they took a bold stand by challenging the constitutionality of prohibition laws. Their case, famously called the “Trial of the Plant,” attracted national and international attention.

While their legal fight was front and centre, the Dagga Couple also understood the power of visuals and media in shaping public opinion. They used photography, videos, and social media to humanise cannabis users, dispelling myths and reducing stigma.

This approach has inspired a wave of cannabis-related art in South Africa that combines documentary photography with grassroots activism. Artists and photographers capture the everyday stories of growers, patients, and advocates, weaving them into powerful visual narratives that underscore the need for reform.

Global Voices: Prohibition Art Beyond South Africa

South Africa’s story is part of a global movement where artists have used cannabis prohibition as subject matter and inspiration. Around the world, cannabis art has fueled social movements, chronicled cultural shifts, and challenged authorities.

In the United States, the counterculture movement of the 1960s and 70s produced some of the most iconic cannabis-related art. Psychedelic posters, album covers, and underground zines celebrated cannabis as a symbol of peace, freedom, and creativity. Artists like Rick Griffin and Victor Moscoso created vibrant, surreal posters that became emblems of cannabis culture and protest.

British-born South African writer and activist Lee Harris was significant in this cultural wave. Though not an artist in the traditional visual sense, his founding of Home Grown magazine in the 1970s provided an essential platform for cannabis counterculture and advocacy in the UK and beyond. His work helped spread ideas and imagery about cannabis liberation that resonated with South Africans and other activists worldwide.

Meanwhile, Mexican muralists, Jamaican reggae album art, and European street artists have all contributed to cannabis prohibition art, each reflecting their unique social and political contexts. This international exchange of ideas and styles has helped local movements like ours gain strength and visibility.

How Art Shapes Public Perception and Policy

Art’s role in the cannabis legalisation movement isn’t just cultural—it’s political. Visual art can reach audiences on emotional and intuitive levels that legal arguments or statistics can’t. It humanises the struggle, breaks down fear, and builds empathy.

In South Africa, the blend of historical resistance art, contemporary activism visuals, and personal storytelling through imagery has helped shift public attitudes. The gradual change in laws—from full prohibition to partial decriminalisation for personal use—has been accompanied by a flourishing of cannabis art in galleries, festivals, and public spaces.

The art of cannabis prohibition also reminds us to celebrate and uplift those who carried the fight through decades of repression. It honours the growers, patients, activists, and creatives whose courage and creativity brought the movement forward.

Looking Forward

As South Africa moves deeper into the legal cannabis era, the role of art will evolve but remain vital. Cannabis-inspired fashion, design, and branding are legally emerging alongside traditional activist art. The challenge will be maintaining authenticity and social justice values amid growing commercialisation.

Future cannabis art will likely explore new themes—equity, environmental sustainability, indigenous knowledge, and the intersection of cannabis with technology and wellness. Artists will continue to be storytellers and guardians of cannabis culture, ensuring that the plant’s rich history and transformative potential aren’t forgotten in the rush to profit.

Art as a Legacy and a Catalyst

Cannabis prohibition art in South Africa connects past struggles with future possibilities, weaving local and global voices together in a mighty chorus for change.

Whether through bold murals in township streets or the global influence of counterculture artists, the creative spirit that cannabis inspires remains a force to be reckoned with. In celebrating this art, we celebrate the resilience and humanity of all who have fought to reclaim the right to the plant and freedom.
