What do Heroin Eyes Look Like?
In light of the United States’ opioid epidemic, people frequently wonder what the signs and symptoms of opioid use are, including “heroin eyes.”
One of the signs that are most frequently recognized is “heroin eyes.” But what do heroin eyes look like, and what causes them? Below is general information about the signs of heroin use, and more specifically, heroin eyes.
People on heroin may also scratch their skin, vomit, have poor grooming or hygiene habits, or cover their arms and legs with long sleeves, even when the weather is warm. Weight loss, scabs or sores on the skin, and slurred speech may also be signs of heroin abuse.
Sudden weight loss, needle tracts or scarring along veins, dark circles under the eyes, burn marks on the fingers or hands, and puffiness under the eyes may indicate a problem with heroin also.
While these signs can be telling, sometimes the most notable physical sign of heroin use is the effect heroin has on the eyes.
People who recently used heroin will often have very small pupils, and their eyes may appear to be droopy. It may also make the eyes appear more red and bloodshot.
Some of the signs of a heroin overdose include slack, flaccid muscles, loss of consciousness, being conscious but unable to speak, and breathing that’s slow, shallow, erratic or seems to have stopped altogether. Other signs of a heroin overdose can include choking sounds, or sounds like snoring or gurgling, vomiting, pale, clammy skin, and a bluish or purplish tint to the fingernails and lips. Heroin overdose pupils also tend to appear very small, to about the thickness of a nickel. This is often referred to as heroin pinpoint pupils.
So, does heroin make your eyes dilate?
The answer is “no.” Opiates, including heroin, make your pupils constrict, which is called miosis.
So what causes heroin eyes to look this way? Why do pupils constrict when people take opioids like heroin?
When heroin attaches to opioid receptors, it changes the functionality of the entire central nervous system. When pupils constrict or become small because of drug use, it means the drug affects the parasympathetic part of the autonomic nervous system.
Heroin eyes or pinpoint pupils can be one of the telltale signs of heroin or opioid use because the majority of other types of substances have the opposite effect and cause the pupils to appear larger.
