A Fundamental Insight On ‘Vasodilation’ Effect Due To Cannabis 

vasodilation effect due to cannabis

Bloated face, puffy red eyes, dehydrated skin are naturally occurring symptoms for cannabis smokers. Often pinned to smoke irritation, now new studies suggest they might be signs of ‘vasodilation’.

Visible Effects

Vasodilation is a phenomenon that triggers the opening up of the body’s blood vessels. Its reciprocated effect is ‘vasoconstriction’ meaning the closing up of vessels within the body. Although vasodilation effects are temporary, it’s not always necessary that these symptoms occur only when you consume cannabis.

In other words, vasodilation is a natural response that the body produces during and after cannabis consumption. The effects include an increased body temperature, reduction of blood oxygen levels, reddening of the eyes, and puffy face, etc. When you consume cannabis, the blood level of the body lowers in some parts of the body, which means the oxygen transportation is also slowed, and hence the symptoms surface. For patients suffering from glaucoma (high blood pressure), these effects are beneficial.

As a symptom, vasodilation helps glaucoma patients to lower their blood pressure. That said, the researchers have found cannabis useful in multiple applications for the human body.
