How to Read Cannabis Lab Results: THC, CBD & Beyond
Lab results contain valuable information beyond THC percentage. Learn how to interpret cannabinoid profiles, terpene analysis, and safety testing to make informed choices.
Why Lab Results Matter
Cannabis lab testing provides objective data about what's in the product you're consuming. While THC percentage gets most of the attention, a full lab report contains much more useful information.
Understanding Cannabinoid Percentages
THC (Delta-9-Tetrahydrocannabinol)
THC is the primary psychoactive compound. Lab results typically show:
- THC%: The amount of active THC
- THCA%: The acid precursor that converts to THC when heated
- Total THC: THCA × 0.877 + THC (the real number to look at)
A common misconception is that higher THC always means a better experience. Research and consumer reports suggest that the overall chemical profile matters more than THC alone.
CBD (Cannabidiol)
CBD is non-intoxicating and may modulate THC's effects. Even small amounts (1-3%) can influence the experience. Strains are generally categorized as:
- THC-dominant: Less than 1% CBD
- Balanced: Roughly equal THC and CBD
- CBD-dominant: High CBD, low THC
Minor Cannabinoids
Some lab reports test for additional compounds:
- CBG: Often called the "stem cell" cannabinoid
- CBN: Associated with sedation, increases as THC ages
- CBC: Being studied for potential anti-inflammatory properties
- THCV: May suppress appetite at low doses
Terpene Analysis
Premium lab tests include terpene profiles, showing percentages of compounds like myrcene, limonene, and pinene. This data is increasingly recognized as important for predicting effects.
Safety Testing
Reputable labs test for:
- Pesticides: Harmful chemicals from cultivation
- Heavy metals: Lead, arsenic, mercury, cadmium
- Microbials: Mold, bacteria, and other pathogens
- Residual solvents: Leftover extraction chemicals
- Mycotoxins: Toxins produced by mold
