![]() ![]() Research has shown that animals previously exposed to cocaine are more likely to seek out cocaine in highly stressful situations. The ventral tegmental area communicates stress cues as well as drug cues, which include cocaine seeking behaviors. ![]() The ventral tegmental area overlaps both the stress and reward circuits of the brain, and cocaine impacts this area significantly. ![]() This binging pattern can lead to permanent changes to the function of the brain, neural pathways and structures of the brain.Īs dopamine and glutamate continue to be released in increasingly high amounts in the reward centers of the brain, cocaine use also affects the stress response area of the brain. The euphoric effects of cocaine do not last long, which often leads to repeated use over a short period of time. This area of the brain is believed to play a significant role in cocaine addiction. Cocaine use increases glutamate release in the reward center of the brain, including the nucleus accumbens. Glutamate, another excitatory neuron, is also affected by cocaine use. This flood of dopamine is what causes the euphoric feeling associated with cocaine, but dopamine has long been connected to other important functions of the brain and addiction as well. Instead of the brain cleaning up the dopamine and using it another day, the dopamine remains active while on cocaine. Cocaine Effects On The BrainĬocaine use stimulates the brain and opens a floodgate of dopamine that surges into the brain. People on cocaine may even wear sunglasses when it doesn’t seem bright to others.Ĭocaine also causes expansion of blood vessels, which can result in bloodshot eyes or the whites of the eyes may appear red.Ĭall now to talk with a treatment specialist about your recovery options. This specific action is what is referred to as cocaine eyes.Įxtreme dilation of the pupils results in a sensitivity to light, as more light is let in through the pupil. Eyes tend to be the telltale of substance use, and cocaine use is no different.Ĭocaine is a stimulant that causes chemical and endorphin release in the brain, and as a result the pupil of the eye dilates. Cocaine tends to affect the eyes in a couple different ways.Īlmost all drugs cause changes in the eyes, whether they dilate or pinpoint, become bloodshot or glassy. What Are Cocaine Eyes?Ĭocaine eyes, also known as cocaine pupils, refer to how the pupils appear after they have taken cocaine. ![]() The CNS system, including the brain, is directly affected by cocaine use, and the following information provides insight into how cocaine can affect the body. Available on the street as an illegal stimulant drug, usually referred to as blow, powder, snow or coke.Ĭocaine can be snorted in powder form, or can be modified in a number of ways to be injected, smoked or inhaled in a process called freebasing.Ĭocaine effects tend to only last a short time, and people often end up binging on cocaine to maintain the high of the drug.Ībusing cocaine comes with many risk factors, which include unpredictable behavior, addiction, changes in the brain (permanent and temporary), cardiovascular issues, respiratory problems and other organ system complications.Īs part of the central nervous system (CNS) the visual system is affected by cocaine use. Cocaine is a white, crystal like, fine powder. ![]()
