Buying cannabis products can be overwhelming, especially with the amount of information packed onto labels. Understanding how to read a cannabis product label ensures you’re making informed choices about potency, ingredients, safety, and compliance. Here’s what you need to look for when selecting a cannabis product.
1. THC & CBD Content
One of the most important sections of a cannabis label is the cannabinoid content, usually displayed in milligrams (mg) or percentage (%).
✔ THC (Tetrahydrocannabinol) – The main psychoactive compound that produces a “high.” ✔ CBD (Cannabidiol) – A non-intoxicating cannabinoid known for its potential therapeutic benefits. ✔ Total THC/CBD – The activated amount of THC or CBD when the product is consumed (after decarboxylation).
Example: A flower product may list:
THC: 18% (180 mg per gram)
CBD: 2% (20 mg per gram)
2. Product Type & Strain Information
Labels indicate the form of cannabis, such as:
Dried flower (Indica, Sativa, Hybrid)
Pre-rolls
Edibles (gummies, chocolates, beverages)
Extracts & Concentrates (vapes, shatter, hash, distillates)
Topicals & Tinctures
Knowing the strain type helps users predict effects: ✔ Indica: Relaxing, calming, good for nighttime use. ✔ Sativa:Energizing, uplifting, ideal for daytime. ✔ Hybrid: A mix of both, effects depend on the strain.
3. Terpene Profile (If Available)
Terpenes are aromatic compounds that contribute to flavour, aroma, and effects. ✔ Myrcene: Sedative, relaxing, common in Indica strains. ✔ Limonene: Citrus-scented, uplifting, anti-anxiety. ✔ Pinene: Earthy, enhances focus and memory. ✔ Caryophyllene: Spicy, anti-inflammatory, interacts with CB2 receptors.
Not all cannabis labels display terpene content, but high-quality brands often include this information.
4. Ingredients & Additives (For Edibles, Vapes & Tinctures)
For edibles and infused products, check the ingredient list for: ✔ Natural vs. artificial flavours ✔ Sugar content & allergens ✔ Preservatives or additives
For vape cartridges and extracts, look for: ✔ No harmful thinning agents like vitamin E acetate. ✔ CO2-extracted or solvent-free options for purity. ✔ Full-spectrum vs. isolate: Full-spectrum retains all cannabinoids and terpenes.
5. Expiry Date & Storage Instructions
Cannabis products degrade over time. Labels include: ✔ Packaged on Date – When the product was sealed. ✔ Best Before Date – Recommended timeframe for freshness. ✔ Storage Instructions – Keep in a cool, dark place to preserve potency.
6. Health Warnings & Legal Compliance
Cannabis products in Canada must include Health Canada-mandated warnings, such as: 🚨 "Keep out of reach of children." 🚨 "Cannabis can impair concentration and coordination. Do not drive or operate heavy machinery." 🚨 "Regular use can increase the risk of dependence."
All legal cannabis must have an Excise Stamp, proving the product is licensed and taxed correctly.
7. Batch Number & Lab Testing Information
Each product has a batch number that links it to lab testing results for: ✔ Pesticide and contaminant screening ✔ Heavy metal testing ✔ Cannabinoid potency verification
Some brands provide a QR code that allows consumers to scan and view lab reports for extra transparency.
Conclusion
Understanding cannabis product labels helps consumers choose the right product, dose correctly, and ensure safety. Look for key details like THC/CBD content, strain type, ingredients, and terpene profiles, and always verify lab-tested compliance.
