One word can hide several questions.

“Cannabis” may refer to a plant, a product, a compound, or a policy category. Start by asking which one the source means.

Use the reading guide

Separate terms

THC and CBD are different compounds. Labels and product categories can use familiar words in confusing ways.

Trace the claim

Look for the original study, agency page, or legal text behind a headline or product statement.

Keep limits visible

Distinguish established findings, uncertainty, and marketing language. A source summary is not personal advice.
