Drugs are made of chemicals, many similar to the chemicals already in our system.
What happens to your brain when you take drugs?
The neurotransmitter dopamine is central to this. Image Simple activities in everyday life can produce small bursts of neurotransmitters in the brain bringing pleasurable feelings. This too amplifies or disrupts the normal communication between high how drugs work. Other drugs, such as cocaine or methamphetamine, can cause the nerve cells to release abnormally large amounts of natural neurotransmitters, or prevent the normal recycling of these brain chemicals, which is needed durgs shut off the al between neurons.
The brain is often likened to an incredibly complex and intricate computer. Examples include:. Drugs can alter important brain areas that are necessary for life-sustaining functions and can drive the compulsive drug use that marks addiction. If a neuron receives enough als from other neurons that it is connected to, it fires, sending its own al on to other neurons in the circuit.
