These can all indicate intoxication. When they are perceived consistently in a person, along with other health consequences like changes in hair, teeth, skin, mental health, and social habits, they can indicate problematic substance use. Changes in the eye, such as pupil size, motion, and color of the whites, can be used to assess whether a person is intoxicated as well.
Changes in the eye’s general color or motion can show intoxication. Bloodshot eyes are a common symptom of intoxication from several drugs, especially alcohol, cocaine, and marijuana; these occur because blood vessels in the eyes expand. Other drugs may cause the eyes to water, the eyelids to become heavy, or the pupils to change size; in fact, pinpoint pupils are a symptom of opioid intoxication and overdose.Common signs of intoxication indicated by the eyes include:
The brain often compensates for early stages of visual changes and eye damage; however, medical treatment will often become necessary to reduce the progress of damage if substance abuse continues for a long time.
Substance abuse is correlated with long-term problems with vision due to damage to the eyes.
Changes in the eye associated with intoxication may lead to attempts to cover up the problem. Red, bloodshot eyes are a common sign of marijuana intoxication, so it has become part of stoner culture to attempt to cover the problem by using eyedrops. Double or blurry vision from alcohol or opioid intoxication can cause the person to hyperfocus on an object or person in an effort to cover the symptoms. However, changes in pupil size, alterations in eye movements, and hallucinations are nearly impossible to hide, and they are reliable symptoms of intoxication on many drugs of abuse.
When a person struggles with addiction and substance abuse for a long time, they are more likely to suffer serious health problems. Diabetes, blood pressure problems, heart damage, liver and kidney damage, cancer, and ulcers in the stomach and small intestine are just a few of the frequently reported health consequences of drug abuse.
Substance abuse is also correlated to long-term problems with vision due to damage to the eyes, ocular nerve, and the brain. Here are a few long-term problems to the eyes caused by drug addiction and abuse:
Damage to the eyes, vision, and brain are a few among many serious health consequences associated with substance abuse and addiction. Nearly any intoxicating substance can cause these problems, especially when a person ingests drugs or alcohol in large quantities for a long time. The best way to prevent or slow these side effects is to detox, with the help of a medical professional, and enter a rehabilitation program to overcome the addiction.
