Impaired coordination, learning issues, and sleep problems can result from long-term marijuana use and its impact on the brain. Clapp, J., Reed, M., Holmes, M., Lange, J., & Voas, R. (2006). This increased activity reduces brain activity, resulting in the relaxing effect of these drugs. These drugs are called opioids partly because they activate the opioid receptors on nerve cells, mimicking the effects of pain-relieving chemicals that would otherwise be produced naturally. A depressant is a drug that tends to suppress central nervous system activity (Figure SC.15). Ecstasy is also commonly combined with alcohol or other drugs, or cut with toxic substances, which can have potentially hazardous consequences. anxiety.

Psychoactive drugs affect the central nervous system in various ways by influencing the release of neurotransmitters (chemical messengers within the nervous system, such as acetylcholine, serotonin, dopamine, norepinephrine), or mimicking their actions. These drugs operate by affecting neurons (nerve cells) in the CNS, which leads to symptoms such as drowsiness, relaxation, decreased inhibition, anesthesia, sleep, coma, and even death. Despite the fact that young people have experimented with cigarettes, alcohol, and other dangerous drugs for many generations, it would be better if they did not. Higher doses of this drug can cause a person to experience erratic behaviors, including violence, anxiety, panic, and paranoia.
