A small toolkit for reading cannabis claims

Name the thing

Separate plant, compound, and product.

THC and cannabidiol (CBD) are compounds found in cannabis. THC is associated with the intoxicating “high”; CBD does not produce that same high. Products may contain different compounds and concentrations, and the words used in the marketplace do not by themselves establish quality or effect.

Trace the evidence

Find the source behind the statement.

• For a health claim, look for the public-health agency or peer-reviewed study being cited.
• For a product claim, check whether the source is a seller, a regulator, or an independent investigation.
• For a statistic, record the population, date, and definition used.
• For a legal statement, identify the jurisdiction and the date; rules can change.

When a link leads only to another summary, keep following citations until you reach the underlying source—or mark that you could not.

Read public-health pages carefully

Notice both findings and uncertainty.

CDC describes potential effects on brain function, heart rate, driving, lungs, and other outcomes. It also notes where relationships are not fully understood. Keep those distinctions intact when summarizing a source.

Check product claims

Marketing language is not an evaluation.

FDA explains that many cannabis-derived products have not been evaluated or approved as drugs and raises concerns about unsupported medical claims and product quality. A label, testimonial, or “natural” claim is not proof of safety, effectiveness, or consistent contents.

Use the right kind of help

This guide is for source literacy.

It does not offer medical or legal advice, assess a particular product, or make recommendations about use. For a health question, speak with a qualified health professional. For a legal question, consult official sources in the relevant jurisdiction or a qualified attorney.
