Walking into a dispensary for the first time (or even your fifth time) can feel a little overwhelming. The shelves are full of colorful packages covered in numbers, percentages, strange words like “terpenes,” and lots of fine print.
You’re not alone if you’ve ever picked up a product and thought, “What does all this actually mean?”
First Things First: Look for the Universal Symbol
This symbol serves as a quick visual cue that the product has been tested and is regulated by the state. If you don’t see it, put the package back. It’s one of the easiest ways to know you’re buying safely.
You’ll also notice several required warnings on every label, such as:
- “For use by individuals 21 years of age or older only.”
- Warnings about not driving while impaired
- “Women should not use marijuana during pregnancy or while breastfeeding”
- “Keep out of reach of children.”
These are there for good reason – always read them.
The Big Picture: What Michigan Labels Must Show
Michigan rules require clear labeling so you know exactly what you’re getting. Look for these key details:
- Licensee name and license number (of the grower/processor and retailer)
- Batch or lot number (for traceability in case of any issues)
- Harvest or manufacture date
- Net weight (in grams and ounces)
- Ingredients list and allergen warnings (especially important for edibles)
Michigan rules require clear labeling so you know exactly what you’re getting. Look for these key details:
Potency: Understanding THC, CBD, and Total Cannabinoids
This is usually the part that confuses beginners the most.
- THC (Delta-9 THC): The main compound responsible for the psychoactive “high.” On vapes, edibles, and concentrates, you’ll mostly see already-activated THC listed in milligrams (mg).
- THCA: Found mostly in raw flower. THCA is non-intoxicating until you heat it (by smoking, vaping, or cooking). That’s why flower labels often show both THC and THCA.
- Total THC: This is the number you should pay the most attention to on flower. It tells you the potential potency after heating.
- The simple formula labs use is:
Total THC ≈ (THCA × 0.877) + THC - Don’t worry – you don’t need to do the math yourself. Many labels now show “Total THC” directly. A flower labeled 22% Total THC will feel significantly stronger than one labeled 12% Total THC.
- CBD: The non-intoxicating cannabinoid often associated with calm and balance. Products may display a THC : CBD ratio (such as 1:1 or 20:1). A higher CBD content can help mitigate the intensity of THC for some individuals.
- TAC (Total Active Cannabinoids): The combined percentage or milligrams of all cannabinoids in the product. This gives you a broader view of the product’s overall strength.
Pro Tip for Edibles & Drinks: Always check mg per serving and mg per package. A gummy package might contain 100mg total THC, but each piece could be only 10mg. Start low – especially if you’re new.
Terpenes: The Secret Behind Flavor and Feeling
Two products with the same THC percentage can feel completely different. That’s largely thanks to terpenes – the natural aromatic compounds that give cannabis its smell, taste, and nuanced effects.
Look for the terpene profile on the label (many quality products list the top terpenes with percentages). Here are a few common ones to know:
- Myrcene (earthy, musky): Often associated with relaxing, body-heavy effects.
- Limonene (citrusy): Uplifting, mood-boosting, and great for creativity.
- Pinene (pine/fresh): May support alertness and focus.
- Linalool (floral, lavender-like): Calming and potentially helpful for sleep or anxiety.
- Caryophyllene (spicy, peppery): Known for its anti-inflammatory properties.
The combination of cannabinoids + terpenes creates what’s called the entourage effect – the idea that the whole plant works better together than any single compound alone.
Other Helpful Details on the Label
- Strain name and type (Indica, Sativa, or Hybrid) – useful as a general starting point, though effects are influenced more by terpenes and cannabinoids than the label alone.
- Lab testing information: Look for the lab name and test date. Reputable products will have passed tests for pesticides, heavy metals, molds, and residual solvents.
- Expiration or “Best By” date
- Suggested use or activation time (especially on edibles)
Product Type Differences
- Flower / Pre-rolls: Focus on Total THC % and terpene profile.
- Vapes & Concentrates: These are often very potent – check total cannabinoids and start with small puffs.
- Edibles & Cannabis Drinks: Milligrams per serving is everything. Effects can take 30–120 minutes to kick in and last longer.
- Topicals & Tinctures: Usually list mg of THC or CBD per application and are less likely to cause psychoactive effects.
Your Quick Label Checklist (Save This!)
- Do I see the Michigan universal symbol
- What is the Total THC (or mg per serving)?
- What are the dominant terpenes?
- Does the cannabinoid profile match my goal (relax, focus, uplift, sleep, etc.)?
- Any allergens or warnings I should note?
Common Beginner Mistakes to Avoid
- Choosing only by the highest THC percentage (terpenes and balance often matter more for the experience you want).
- Ignoring serving size on edibles.
- Not checking the batch test date (fresher is usually better).
- Assuming “10% THC” on flower feels the same as “10mg THC” in an edible.
