Certain drugs cause constriction of the pupils, such as alcohol and opioids.Other drugs, such as atropine, marijuana, LSD, cocaine, mescaline, psilocybin mushrooms, and amphetamines cause pupil dilation.
In most other circumstances, pupil dilation from medications or drugs is considered a side effect.
The most noticeable factor is pupil dilation, though a good number of other drugs can cause that as well.
Over-the-counter (OTC) medications that can cause pupil dilation include certain antihistamines, such as diphenhydramine (Benadryl). These medications can have anticholinergic effects, leading to pupil dilation as a side effect. Additionally, some decongestants may also contribute to this effect. However, pupil dilation is primarily associated with prescription medications and recreational drugs rather than OTC options.
yes it does
Yes and no. Depends on what kind you take.
Listing them all would be time-consuming so lets put it this way. Drugs can cause a pupil to change in two ways by dilation making the pupil larger or constricting the pupils. Only two drugs constrict the pupils those being opiates and alcohol. So anything but, these can cause the pupils to dilate.
Typically, no alcoholic beverage will cause pupil dilation.
dilation of the pupil.
Yes, but not so much as most people would notice. Pupil dilation (where the pupils--the dark portion at the center of the eyes-- get bigger) occurs naturally in low light, so that more light can reach the retina at the back of the eye. Alcohol artificially dilates the pupils consistent with the amount of alcohol in the person's bloodstream. Other recreational drugs, such as marijuana, cocaine, methamphetamine and LSD cause more profound dilation, so much that pupil dilation is a valuable diagnostic indicator of intoxication with these drugs.
Pupil dilation is controlled by the autonomic nervous system in response to changes in light or emotion. The muscles in the iris contract or relax to adjust the size of the pupil, allowing more or less light to enter the eye. Stress, medications, and certain medical conditions can also affect pupil size.
The visible colored part of the eye that controls pupil dilation is the iris. The iris regulates the size of the pupil in response to light conditions and helps to control the amount of light that enters the eye.
Alcohol and opiates cause contraction. Most other drugs cause dilation.
