Certain drugs cause the pupils of the eyes to dilate because of their effects on the parasympathetic or sympathetic nervous systems. SSRI antidepressants, amphetamines, ecstasy, cocaine, psilocybin, LSD, and mescaline can cause dilated pupils.

And, of course, dilation can be caused by over-the-counter, prescription, or illegal drugs. In fact, neurotransmitters that are activated by many prescription medications can make the pupils dilate as well. The ingredients of the drug, what the substance activates, withdrawal from the drug, or overdose may all have something to do with dilation.

Many drugs, however, contradict this primary function by hijacking chemical processes to adjust pupil size. Most stimulants and psychoactive drugs, such as speed and LSD, cause dilated pupils. Sudafed, cocaine, and heroin withdrawal each have a similar effect.
