Abstract
The global march towards legalization of marijuana consumption is pursued in reason of the supposed harmless properties of this plant. Actually, a wide range of cannabinoids is endogenously produced and interacts with different classes of receptors ubiquitously distributed in the human body. Such endocannabinoid system (ECS) modulates several functions in health and disease. However, studies on synthetic ligands with selective agonist/antagonist activity on specific cannabinoid receptors, have clarified how complex the cannabinoid system is. The whole biological activity of cannabis sativa remains difficult to establish, due to the fact that it is a complex mixture of phytocannabinoids with different or even opposing effects. Δ9-tetrahydrocannabinol is the most represented phytocannabinoid in the marijuana plant and then the most studied compound. It has been widely associated with adverse CV effects in marijuana smokers. Conversely, less is known about the role of other phytocannabinoids. Here, we summarized the current knowledge about the effects of phytocannabinoids in CV disease, mainly focusing on atherosclerosis and myocardial infarction. We critically discussed clinical and experimental evidence linking phytocannabinoids to CV disease, attempting at explaining some controversies and suggesting the direction for future studies.
