How do Drugs and Alcohol affect the Brain?


Drugs interfere with the way neurons send, receive, and process signals through Neurotransmitters. Drugs such as marijuana and heroin activate neurons because their chemical structure mimics that of a natural Neurotransmitter. This allows the drugs to attach onto and activate the neurons. Since they do not activate neurons in the same way as a natural neurotransmitter, they lead to abnormal messages being sent through the network.

Drugs such as Amphetamine or Cocaine interfere with transporters, causing the neurons to release abnormally large amounts of natural neurotransmitters. Sometimes they prevent the normal recycling of these brain chemicals. This too amplifies or disrupts the normal communication between neurons.


Difficulty in walking, blurred vision, slurred speech, slowed reaction times, impaired memory are some of the ways  Alcohol affects the brain. Some of these impairments are detectable after only one or two drinks and quickly resolve when drinking stops. Heavy consumption over a long period of time may have brain deficits that persist well after the addict achieves sobriety.

Heavy drinking has extensive and far–reaching effects on the brain, ranging from simple “slips” in memory to permanent and debilitating conditions that require lifetime custodial care. And even moderate drinking leads to short–term impairment.

Recovery from Drugs and Alcohol Addiction:

In order to recover from addiction, there needs to be a willingness to change. There are some who go to treatment as a way to Detox, and they believe that all their problems will be solved. The reality of the situation is that drugs and alcohol are only a symptom of the disease of addiction. Those who suffer from addiction are stuck in their own ways for a long time. Feelings of anger and self-pity fuel addiction, which is why it’s important to be willing to change.
