'''Vasodilation''' can be described as a widening of the veins and blood vessels which results from the relaxation of smooth muscle cells within the vessel walls. It is particularly prevalent in the large arteries and small arterioles. The primary function of vasodilation is to increase blood flow in the body to tissues that need it most. In essence, this process is the opposite of [[vasoconstriction]], which is the narrowing of blood vessels.

[[THC]] and other [[cannabinoids]] cause vasodilation by decreasing blood pressure; this dilates the blood vessels and increases blood flow throughout the body. The arteries in the eyeball expand from the decreased blood pressure and this often results in a bloodshot red eye effect and relief from glaucoma. ~~<ref>Cardiovascular Effects~~ of ~~Cannabis~~ | ~~http://www.idmu.co.uk/canncardio.htm</ref> <ref>Is Marijuana an Effective Treatment for Glaucoma?~~ | ~~http://medicalmarijuana~~.~~procon.org/view.answers~~.~~php?questionID=000140</ref>~~

This effect is typically very difficult to consciously perceive but often results in a bloodshot red eye effect and relief from glaucoma.

Vasodilation is often accompanied by other coinciding effects such as [[decreased blood pressure]]. It is most commonly induced under the influence of [[dosage#common|moderate]] [[dosage|dosages]] of [[cannabinoid]] compounds, such as [[cannabis]], [[JWH-018]], and [[THJ-018]]. However, it can also occur under the influence of [[poppers]] and [[viagra]].
