The chemical compositions of the hallucinogens are similar to the neurotransmitters serotonin and epinephrine, and they act primarily by mimicking them. 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. What are the potential implications of the research for drug use? Sedation, amnesia, muscle contractions and seizures, aggression and violence, psychotic symptoms resembling schizophrenia, and immobility may also occur. Effects of stimulants include increased heart and breathing rates, pupil dilation, and increases in blood sugar accompanied by decreases in appetite. They work by influencing neurotransmitters in the CNS. Learn more about how Pressbooks supports open publishing practices. MDMA (ecstasy, molly) drug facts.

Opioids have become a national epidemic. Opioids are particularly addictive because long-term use changes the way nerve cells work in the brain; even when someone is taking them as prescribed to treat pain. Concurrent use of cocaine and alcohol is more potent and potentially more toxic than use of either aloneA multiple-dose study 1. We avoid using tertiary references. It may be the oldest drug on record, known to the Sumerians before 4000 BC. Nicotine, which people can find in smoked and chewed tobacco products, is a stimulant and depressant.

It is much less likely to lead to antisocial acts than that other popular intoxicant, alcohol, and it is also the one psychedelic drug whose use has not declined in recent years (National Institute on Drug Abuse, 2009). Alcohol increases the likelihood that people will respond aggressively to provocations (Bushman, 1993, 1997; Graham, Osgood, Wells, & Stockwell, 2006). Drugs interact with the brain and body to alter moods, emotions, and behaviors by changing brain chemistry and a persons perceptions, and by impacting how individuals interact with the world around them. Medline Plus. Alcohol use is highly costly to societies because so many people abuse alcohol and because judgment after drinking can be substantially impaired. In North America, more than 80% of adults consume caffeine daily (Lovett, 2005). (2007). Bushman, B. J. When someone abuses marijuana, impaired motor skills, mood alterations, distorted time and sensory perception, decreased memory, and trouble thinking clearly and solving problems are all common short-term side effects. A stimulant is a psychoactive drug that operates by blocking the reuptake of dopamine, norepinephrine, and serotonin in the synapses of the CNS. Opioid overdose is an all too common consequence of opioid abuse, which can often result in severe respiratory depression that can be fatal. Dissociative drugs can make people feel separate from themselves, their environment, and reality. Ben Amar, M. (2006). Depressants: These drugs slow down activity in .

The chemical compositions of the hallucinogens are similar to the neurotransmitters serotonin and epinephrine, and they act primarily as agonists by mimicking the action of serotonin at the synapses.

MDMA is a very strong stimulant that very successfully prevents the reuptake of serotonin, dopamine, and norepinephrine. Cocaine is a stimulant that is illegal in many countries. Depressants inhibit the CNS, increasing the activation of the GABA neurotransmitter.
