Adolescents, whose amygdalae are less under control by their frontal lobes, are prone to responding to situations of stress with more extreme emotions than adults, who can rely on their prefrontal cortex within the frontal lobes to control their anger and fear.

teens may be less protected against stress compared with adults because of the way they respond to the stress hormone THP. Instead of a calming effect, the hormone stirs up additional anxiety in the teen.

Emotionally, the main difference between adults and adolescents is that there is much less activity in the frontal lobes of adolescents, making it harder for them to handle their emotions, especially in crisis situations.

The negative side effects of Ecstasy are considerable—confusion, agitation, irregular heartbeat, seizures, sleep disorders, liver and brain damage, and of course death

This is not minor or incidental. These brain regions are used every day for basic cognitive tasks, whether it’s abstract thinking, the ability to change one’s behavior in relation to changing demands in the environment, or the inhibition of inappropriate responses.

Adolescent brains are not as resilient as adult brains when it comes to marijuana. Teenagers are especially vulnerable to the drug because they are at a critical stage in the development of two of the most sophisticated part of their brains—the frontal and prefrontal cortex—and these are precisely the parts most affected by marijuana.

A study done in Great Britain found evidence to support the conclusion that cannabis use was an important causal factor in the development of schizophrenia and that smoking marijuana doubles the risk of psychosis.

Marijuana use has also been observed to inhibit functioning in the areas of the cortex that play a critical role in recognizing errors, specifically insight into one’s own thoughts and behavior. Neurologists and neuroscientists have associated the inability to detect errors with several psychopathologies, including the psychotic delusions of schizophrenia

There are more problems with the amygdala the day after smoking pot, too. Having already been overstimulated by THC, the amygdala now has fewer cannabinoid receptor sites; this means it takes more than the normal amount of stimulation to get the brain interested in learning something new. How to do it? By smoking more pot, of course.
