Cannabis use is increasing globally, but its cardiovascular effects remain unclear. Current research shows no confirmed link between cannabis and heart disease, though more studies are needed.
Area of Science:
- Cardiovascular Science
- Pharmacology
Background:
- Global recreational drug use is rising, with cannabis being the most common.
- Increased legalization of cannabis for recreational and medicinal purposes necessitates understanding its cardiovascular impact.
Purpose of the Study:
- To review the current literature on the pathophysiology of endocannabinoids.
- To examine the hemodynamic effects of cannabis.
- To assess the association between cannabis use and cardiovascular outcomes.
Main Methods:
- Literature review of existing studies.
- Analysis of molecular and retrospective data.
- Evaluation of prospective clinical data, including the CARDIA study.
Main Results:
- The endocannabinoid system influences the cardiovascular system at a cellular level.
- Existing studies on cannabis and cardiovascular health yield inconclusive results.
- The CARDIA study found no association between cannabis use and cardiovascular events.
Conclusions:
- While molecular and retrospective data suggest potential negative cardiovascular effects of cannabis, prospective clinical data have not confirmed these findings.
- Further research is required to definitively establish any association between cannabis and cardiovascular disease.

Overview of the Cardiovascular System
Heart
The heart is the central pump of the cardiovascular system that circulates blood throughout the body. It comprises two atria receiving the blood and two ventricles pumping blood out of the heart. Their rhythmic contractions, called heartbeats, ensure that blood flow remains continuous.
Blood Vessels

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
