It's one of the recurring questions around smokers: why do their eyes turn red after smoking?

THC is the cause of this physiological change. It causes a dilation of blood vessels and increased blood flow in the body. Blood vessels, barely visible at rest, become bolder and swell in the eyes. In fact, this is the only place where the increase in blood vessels can be noticed.

The THC is used for medical purposes to treat patients suffering from glaucoma, a disease that can lead to blindness. This pathology is caused by intraocular hypertension, the opposite effect of cannabis on the eyes.

• Cucumber: For toned, rested eyes, place a slice on each eye for 10 minutes.

• The siesta: A great friend of stoner, the nap recharges the batteriess. Beware: if the night was harsh, the opposite effect can occur, with eyes totally blown out by the return to light.
