Drugs can cause a pupil to change in two ways by dilation making the pupil larger or constricting the pupils.â¦ Only two drugs constrict the pupils those being opiates and alcohol. So anything but, these can cause the pupils to dilate.
Some people report pupil constriction when they suffer from anxiety. Constriction is when the pupils get smaller, rather than bigger as they do when they dilate. There doesn't appear to be evidence that anxiety causes pupil constriction, but when stress affects the body almost anything is possible.
