The International Association of Chiefs of Police invented the chart to quickly determine the pupil size difference between sober people and those high on drugs. When there is suspicion of drug abuse, there is a unique tool that officers or medical practitioners can use to determine pupil dilation and the most likely cause.įirst responders use the Drug Recognition Card to determine whether or not an individual is sober. If you notice a heroin user has pinpoint pupils, it would be best to call 911 immediately. Sometimes, pinpoint pupils are an overdose symptom. Pinpoint pupils refer to pupils constricting and failing to respond to light. Other drugs, specifically opioids, can cause pinpoint pupils. Additionally, the stimulant medication used in ADHD treatment, i.e., Adderall and Ritalin, can also cause pupil dilation. Xanax, a benzodiazepine drug, can also make pupils dilate since it affects the activity of neurotransmitter GABA that relaxes the muscles. Some common drugs that cause pupils to dilate are: Most of them are psychotropic substances and stimulants. There are specific drugs that can cause eye dilation. Since neurotransmitters determine your pupil size, they may dilate after drug use. Therefore, they cause chemical reactions in your body, affecting neurotransmitters. Several drugs can alter pupil size since most drug interactions in the body affect neurotransmitters which are your body’s chemical messengers. This results in a chemical reaction that leads to muscle relaxation (mydriasis), making the pupils expand to allow more light in. Pupil dilation after drug abuse occurs when the drugs activate your body’s flight or fight adrenaline response by engaging adrenergic receptors in the brain and serotonin. What is pupil dilation, and why does it occur?
