Visual haze
Visual haze can be described as an effect which distorts the surrounding environment to make it appear as if the air is shrouded in an imaginary cloud of smoke, fog, or haze. This effect varies in its intensity, ranging from subtle and barely visible to extreme and all-encompassing to the point of significantly impairing one's vision. This is commonly an effect with deliriants, such as DPH, and is commonly reported to occur on cannabis and psychedelics in some users as well.
