How does the nicotine in e-cigarettes affect the brain? [6] Until about age 25, the brain is still growing. [6] Each time a new memory is created or a new skill is learned, stronger connections – or synapses – are built between brain cells. [6] Young people's brains build synapses faster than adult brains. [6]
Alcohol acts as a general central nervous system depressant, but it also affects some specific areas of the brain to a greater extent than others. Memory impairment caused by alcohol has been linked to the disruption of hippocampal function—particularly affecting gamma-Aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) neurotransmission which negatively impacts long-term potentiation ...
One form of behavioral neuropharmacology focuses on the study of drug dependence and how drug addiction affects the human mind. Most research has shown that the major part of the brain that reinforces addiction through neurochemical reward is the nucleus accumbens. The image to the right shows how dopamine is projected into this area.

Researchers found that 63% of lifetime heavy cannabis-using participants and 68% of recent cannabis users showed reduced brain activity during their working memory task. “We found that brain ...
“Both types of medications improve cognitive functions like attention and working memory by optimizing neurotransmitter [chemical messenger] levels and enhancing brain network connectivity.”
The change from non-addict to addict occurs largely from the effects of prolonged substance use and the result of behavior activities on brain functioning. Addiction affects the brain circuits of reward and motivation, learning and memory, and the inhibitory control over behavior. [24]
Psychoactive drugs operate by temporarily affecting a person's neurochemistry, which in turn causes changes in a person's mood, cognition, perception and behavior. There are many ways in which psychoactive drugs can affect the brain. Each drug has a specific action on one or more neurotransmitter or neuroreceptor in the brain.
