Heavy cannabis consumption can most certainly result in red-eye, but this can at least be hidden with a pair of shades. By contrast, hit the bottle hard and you might just find yourself with what some refer to as the ‘Asian Glow’. This is basically the informal name given to a reaction that happens in certain people, which leads to the dilation of blood vessels and the inevitable reddening of the skin. You drink no more than a couple of glasses of wine, yet you end up bright red in the face, blotchy and with a kind of shininess that’s nothing short of humiliating. Some people even break out in hives, while others end up with the worst headache long before the hangover even kicks in. With cannabis, nada.
