What cardiovascular effects means
Cannabis can increase heart rate and can produce changes in blood pressure, including dizziness or fainting on standing. Smoke exposure adds combustion products, and effects may matter more for people with cardiovascular disease or interacting medicines.
Cannabis findings depend on the product, dose, route of administration, population, and outcome measured. A result about one cannabinoid or formulation should not be generalized to every cannabis product.
How strong is the evidence?
We weigh systematic reviews and well-controlled human studies above observational reports, case series, animal studies, and laboratory experiments. Each can answer useful questions, but they do not support the same degree of certainty.
Observational studies report associations with stroke and other cardiovascular outcomes, but dose, route, tobacco use, underlying risk, and changing product potency complicate causal estimates. Cannabis is not an established treatment for high blood pressure.
