Research headlines often simplify small studies, animal data, observational findings or products that differ from what patients buy at dispensaries.
Identify the study design
Randomized controlled trials, observational studies, case reports, laboratory studies and surveys answer different questions and carry different levels of uncertainty.
Match the product and population
A purified cannabinoid in a clinical trial is not automatically equivalent to flower, an edible or a multi-ingredient retail product. Age, diagnosis and concurrent medications also matter.
Separate symptom change from cure claims
A reported improvement in pain score or sleep does not prove that cannabis cures the underlying disease. Look at the actual outcome measured.
Use systematic reviews carefully
Reviews can summarize many studies, but their conclusion is only as strong as the included evidence. Read the certainty rating and limitations.
