An Act to amend the Food and Drugs Act (warning label on alcoholic beverages)

The main Canadian study on cancer warning labels for alcohol is the Northern Territories Alcohol Labels Study (Yukon, 2017–2018), a quasi-experimental real-world trial.

Key details:

• New large, colorful labels added to alcohol containers in Whitehorse’s main liquor store (intervention site), including “Alcohol can cause cancer,” low-risk drinking guidelines, and standard drink info.
• Comparison: Yellowknife (NWT) and other Yukon regions with no new labels.
• Cancer awareness increased significantly (e.g., ~10% greater rise in recalling alcohol-cancer link).
• Per capita alcohol sales/consumption dropped ~6.3% in Whitehorse during intervention (vs. controls);
• labeled products specifically fell ~6.6–7%, with larger effects (~10%) after additional phases.
• Self-reported: more people thought about/talked about labels and cut down drinking.
• Published in Journal of Studies on Alcohol and Drugs (2020); led by Erin Hobin & Tim Stockwell.

Europe (2024 Lancet study): Online experiment in 14 countries; cancer warnings increased knowledge that alcohol causes cancer by ~32-33% (vs. ~2% for controls). Text-only, pictogram, or graphic versions worked similarly; more effective than general health or responsibility messages.

Chile (2024 randomized experiment): General cancer risk warning reduced alcohol purchase choices by ~10.4 percentage points (outperformed pregnancy, driving, or combined warnings).
