YOUR BRAIN ON DRUGS
The brain has great power, directing all of the body's processes. But it does have a weakness—drugs of abuse. When they enter neurological territory, all goes haywire.
First, Let's Get It Straight
Addiction is a disease. Long-term drug use makes the brain malfunction.
There are 3 primary areas of the brain that drug use affects:
Controls thought, planning, problem-solving, decision-making. Doesn't fully develop until age 25, so drug damage in youth is even more devastating.
Controls basic functions Controls pleasure and rewards. like breathing, heart rate, circulation, digestion.
The Brain's 4 Lobes Control Different Processes:
Frontal reasoning,judgement,vouluntary movement.
Temporal hearing, smell.
How Brain Cells Talk to Each Other
100 billion nerve cells that make up the brain.
Sites on neurons where neurotransmitters attach to send their message. (Receptors and neurotransmitters are like locks and keys—they must fit.)
Substances that transmit messages between neurons.
Neurotransmitters transmit messages and then are removed when the message is complete.
Return neurotransmitters when the message is complete.
Brain, Meet Drug
Too Many Neurotransmitters Drugs like cocaine or meth make the brain release too many neurotransmitters like dopamine or don't let the transporters recycle neurotransmitters. Dopamine Receiving Akron.
Drugs Instead of Neurotransmitters
Drugs like marijuana or heroin fool the brain into thinking they're neurotransmitters. They attach to receptors, but then the drugs relay abnormal messages.
How Addiction Happens
The brain naturally produces a certain amount of dopamine in response to pleasurable activities like eating or sex.
Dopainine Drugs short-circuit this natural cycle by making the brain release floods of dopamine.
In response, the brain shuts down some dopamine receptors. The person takes more drugs, even though the brain is not responding the same way.
This increased tolerance lessens the ability to get high. Then conditioning and memory the over and produce cravings he the drug, even though the high is not the same.
