Reading Cannabis Labels: Understanding Dispensary Product Information

Dispensary cannabis products include detailed labels with testing information, potency levels, and other data. Understanding these labels helps you choose products that match your tolerance and goals.

Quick Answer

Cannabis labels show THC% (potency - beginners start with 15-20%), CBD% (non-psychoactive benefits), dominant terpenes (aroma and effect modifiers), strain type (indica/sativa/hybrid), harvest/testing dates, batch numbers, and sometimes minor cannabinoids. Higher THC isn't always better - balanced cannabinoid and terpene profiles often provide the best experiences.

THC Percentage

What It Means

THC% indicates tetrahydrocannabinol content by weight. 20% THC = 200mg THC per gram.

Potency Levels:

• 10-15% THC: Low (good for beginners, CBD-focused)
• 15-20% THC: Moderate (ideal beginner range)
• 20-25% THC: Strong (for experienced users)
• 25-30%+ THC: Very strong (high tolerance needed)

For Beginners:

Start with 15-18% THC. Higher isn't better - it just means you need less. Very high THC increases anxiety risk.

CBD Percentage

What It Means

CBD% shows cannabidiol content - the non-psychoactive compound.

Common Ratios:

• High THC, Low CBD (20:1): Most recreational products, strong psychoactive effects
• Balanced (1:1 or 2:1): Medical use, reduced anxiety, moderate effects
• High CBD, Low THC (20:1): Therapeutic focus, minimal high

For Beginners:

Products with some CBD (even 2-5%) can moderate THC's anxiety effects. Consider 2:1 or 3:1 THC:CBD products.

Terpene Profile

What Terpenes Are

Aromatic compounds that give cannabis its smell and flavor, also influencing effects.

Common Terpenes on Labels:

Myrcene: Earthy, musky. Sedating, relaxing. Most common terpene.

Limonene: Citrus. Mood-elevating, stress relief.

Pinene: Pine. Alertness, memory, anti-inflammatory.

Linalool: Floral, lavender. Calming, anti-anxiety.

Caryophyllene: Spicy, peppery. Pain relief, anti-inflammatory.

Humulene: Hoppy, earthy. Appetite suppressant (opposite of munchies).

Why They Matter:

A high-THC strain with relaxing terpenes (myrcene, linalool) can feel calmer than lower-THC strain with energizing terpenes (limonene, pinene).

Strain Information

Strain Name

Identifies specific genetics (Blue Dream, OG Kush, etc.). Same strain should be consistent across batches.

Type Classification

• Indica
• Sativa
• Hybrid (often with ratio like "60/40 indica-dominant")

---

Testing and Safety Information

Testing Date

When cannabinoid/terpene analysis was performed. Fresher testing is better (within 6 months).

Harvest Date

When cannabis was harvested. Fresher is generally better. Cannabis degrades over time (6-12 months optimal).

Batch Number

Identifier for quality control. Important if you have issues or want to buy same batch again.

Laboratory

Which lab performed testing. Reputable labs ensure accuracy.

Contaminant Testing

Should show:

• Pesticides: Pass/Not Detected
• Heavy Metals: Pass/Not Detected
• Microbials (mold, bacteria): Pass
• Residual Solvents: Pass (for concentrates)

Reading Different Product Labels

Flower Labels:

• THC%, CBD%
• Strain, type
• Weight (1g, 3.5g, 7g, etc.)
• Harvest/test dates
• Terpenes (sometimes)

Pre-Roll Labels:

• Same as flower
• Number of pre-rolls
• Total weight
• Sometimes includes strain mix

Concentrate Labels:

• Much higher THC% (60-90%)
• Extraction method
• Solvent-free or solvent-based
• Consistency type (wax, shatter, etc.)

Edible Labels:

• Total THC/CBD in package
• THC/CBD per serving
• Number of servings
• Ingredients
• Onset time estimate

What Labels Don't Tell You

Individual Response: Labels can't predict how you'll personally respond.

Entourage Effect: Whole-plant effects differ from isolated cannabinoids.

Grow Quality: Two batches of same strain at same THC% can differ in quality based on growing/curing.

Your Tolerance: 20% THC affects beginners and daily users very differently.

Smart Label-Based Decisions

First-Time:

Look for: 15-18% THC, indica or hybrid, recent harvest, reputable lab testing

Managing Anxiety:

Look for: Lower THC, higher CBD (3:1 or 2:1 ratios), terpenes like linalool

Daytime Use:

Look for: Sativa or sativa-dominant hybrid, limonene/pinene terpenes, moderate THC

Sleep:

Look for: Indica, higher THC okay, myrcene terpene, CBN if available
