Signs of drug intoxication or how to determine a drug addict by the eyes

How do I know if a person is a drug addict?

Perhaps the most effective method of visually determining whether a person is taking drugs is pupil determination.

The pupil is called a dark hole in the iris of the eye. It restricts the light flow going to the retina.





A little theory:

Changes in the size of the pupil occur in the wake of light irritation of the retina, reduction of the visual axes of both eyes, eye strain to distinguish objects at different distances from each other, as well as in response to stimuli of different nature. The size of the pupil varies due to two iris muscles: circular, which provides narrowing of the pupil, and radial, which provides expansion.

In a sober person, the pupil is never completely calm. Constant movements of the pupil depend on numerous stimuli: increased human activity, pain, emotional tension, strong fear, sudden sharp stimulus (push, loud sound) lead to dilation of the pupils. So the human body tries to quickly get visual information about the stimulus. In a drug addict, the pupil is in one position (during the action of the drug), sometimes slightly changing by literally 1 mm.

How do you define a drug addict?

The pupil may indicate the type of drug taken. What it looks like is shown in the pictures (photo) 1,2,3

Figure 1 Pupil in the Norm (Man of Worries)





In moderate light is in average size, varying depending on the brightness of the light, the pupil is constantly in motion from narrowed to dilated.

The sharpness of the lighting change also affects, so if you shine a flashlight into the eyes, then in a sober person the pupil will immediately work on narrowing, turning off the bright light, the pupil will expand - this is a sign of normal pupil work, in a drug addict after such manipulations the pupil will be in one position, in which? narrowed or enlarged, look at figures 2 and 3.

Figure 2: The Eyes of a Drug Man





The pupil of a drug addict - Heroin, morphine, poppy drugs, codeine-containing medications (terpincode, codelac, nurofen, etc.) - cause narrowing.

The pupil of the eye is narrowed (small), does not respond to a change in lighting, if you shine a flashlight for a few seconds and turn off, then the pupils will remain in one, narrowed position, for people who understand such situations, the eyes of a drug addict with a narrowed pupil cause suspicion already from a distance of 1-2 meters.

For information, the time of action of such drugs as opiates (opioids), heroin, morphine, codeine, etc. is about 5 hours, by this time the pupils of the eye begin to gradually function, the reaction of the pupil to light is slowing down almost not noticeable, but still it is present. As the active substance (drug) leaves the body, this occurs after 5 hours after use, the addict sobers up and the functionality of the pupil is gradually restored.

Figure 3: The Eyes of a Drug Man





The pupil of the addict - Cocaine, amphetamine, ecstasy, LSD, pervintine (screw in slang) causes a noticeable dilation of the pupils.

The pupil in this position is immediately noticeable, usually the effect of such drugs lasts about 24 hours (except cocaine, which has an effect of 1-1.5 hours), and the pupil can be dilated after a day or more, sometimes coming to the middle position, then expanding again, this happens as a person sobers up.

In some cases, after using pervintine ("screw" in slang), the pupil remains dilated for two days. To check with a flashlight, the pupil remains in an expanded, large state, slightly changing by literally 1 mm, depending on the passage of time taking the drug.

Marijuana, hemp, hashish, etc. can cause both narrowing and dilation of the pupil. After taking this drug, the white of the drug addict's eye becomes pink or reddened, inflamed (inflated) vessels are visible, and the most important thing is that the eyes of the drug addict become "glassy" (glow into the light).

The color of the iris (eye color: blue, gray, hazel) does not play a role, but the darker it is, the more difficult the diagnosis.

If you see a person very often with non-standard pupils, then this is the first sign of drug use.

Usually a person uses one drug. When a child or relative returns home, look into the eyes if the pupil is consistently non-standard and of the same size, either large or small, is a sign of drug use.

Remember, a small or large pupil is a reaction to lighting, darkness.Or in the sun, but a constantly small or large pupil is a sign of use. Change the lighting or turn on and off the flashlight, shining them in the eyes. In a sober person, the pupil will constantly change, narrow in bright light, expand in the dark, the pupil of a drug addict will be in one position (in what position? see the photo of Figure 1,2,3).

If a person has been seen in the use of opiates (heroin, codeine, poppy, tram, zaldiar, etc.), such drug addicts use some tricks to mask the pupil. The trick is that in pharmacies sold a lot of drugs dilating the pupils purposefully and not.

The dilated pupil also indicates withdrawal syndrome (refusal to use, withdrawal, drug hangover).
