Read beyond THC percentage
A potency number is one detail, not a complete product description.

The basics
Start with product form, serving size and units. Then read the batch information. Percent by weight and milligrams per serving answer different questions, so comparing only the printed number can be misleading.
What the evidence means
Commercial products vary in chemical profile. A strain name or a terpene list should not be used as a guaranteed mood forecast. Ask for measured information before accepting a promised experience.
A useful question
What does this number measure, and what other information would help me compare the products?
Sources and further reading
Use the sources to check the scope of each claim. A chemical measurement, a laboratory experiment and a study in people answer different questions.
