This method of drug use provides the highest intensity and quickest onset of the initial rush but is also the most dangerous. Opioid addicts suffer a high rate of infections such as HIV, pericarditis (an infection of the membrane around the heart), and hepatitis B, any of which can be fatal. Three main mechanisms of action of caffeine on the central nervous system have been described. In low to moderate doses, alcohol first acts to remove social inhibitions by slowing activity in the sympathetic nervous system. Psychoactive drugs are usually broken down into four categories: depressants, stimulants, opioids, and hallucinogens. Robins, L. N., Davis, D. H., & Goodwin, D. W. (1974). d. They can interfere with basic functions controlled by the amygdala. Using illegal drugs usually poses a higher risk. Is exercise more effective than medication for depression and anxiety? Cocaine and meth, especially, produce an intense high as they rapidly flood the brain with dopamine. Amphetamine is a stimulant that produces increased wakefulness and focus, along with decreased fatigue and appetite. In the period 1991 to 1997, the percentage of 12th-graders who responded that they perceived great harm in regular marijuana use declined from 79% to 58%, while annual use of marijuana in this group rose from 24% to 39% (Johnston et al., 2004). This class of psychoactive drugs includes ketamine and PCP (phenyl cyclohexyl piperidine or phencyclidine).

Within about an hour after ecstasy enters the bloodstream, it stimulates the activity of serotonin, norepinephrine, and dopamine, NIDA explains. A stimulant is a psychoactive drug that operates by blocking the reuptake of dopamine, norepinephrine, and serotonin in the synapses of the CNS. Journal of Ethnopharmacology, 105, 125. Opioids, including codeine, opium, morphine and heroin, produce euphoria and analgesia by increasing activity in opioid receptor neurons. High enough blood levels such as those produced by guzzling large amounts of hard liquor at parties can be fatal. This results in altered inhibition and judgment, among other effects. It exhausts the systemNeurons exhaust their ability to communicate.Once the drugs are goneShort-term: user feels the opposite of the drugRebound effect while the neurons recover.Over time: the brain adaptsReduces the number of dopamine receptor sitesProduces less dopamineResult: toleranceUser needs larger dose to feel the pleasure rush.Maybe . Which ones? Robins, Davis, and Goodwin (1974) found that the majority of soldiers who had become addicted to morphine while overseas were quickly able to stop using after returning home. For instance, sleeping pills are prescribed to create drowsiness, and benzodiazepines are prescribed to create a state of relaxation. Annual Review of Psychology, 54, 2553; Steele, C.

Alcohol increases the likelihood that people will respond aggressively to provocations (Bushman, 1993, 1997; Graham, Osgood, Wells, & Stockwell, 2006). Amphetamines may produce a very high level of tolerance, leading users to increase their intake, often in jolts taken every half hour or so. Depressants can make people feel sleepy, relaxed, or calm. This can result in impaired motor functions, auditory and visual distortions, memory loss, anxiety, numbness, and body tremors. It can cause an immediate euphoric effect that lasts from a few minutes to about an hour. Beside this, how do drugs affect the central nervous system? These substances can affect awareness, thoughts, mood, and behavior. Snorting cocaine tends to cause a high that averages about 15 to 30 minutes. As tolerance increases, so does the risk of drug dependency, addiction, and withdrawal. In small doses, they can cause a person to feel more relaxed and less inhibited.

Figure 5.13 Use of Various Drugs by 12th-Graders in 2005. For these reasons, stimulants are frequently used to help people stay awake and to control weight. The more often drugs are used, the more they will impact brain chemicals and circuitry, which can lead to drug dependence and withdrawal symptoms when the drugs process out of the body. Stimulants, including caffeine, nicotine, and amphetamine, increase neural activity by blocking the reuptake of dopamine, norepinephrine, and serotonin in the CNS. Some people might also have altered senses, for example, seeing brighter colors. MDMA interferes with the way the brain processes information and stores memories, and with long-term use, these cognitive issues can become more pronounced.

Drug cravings, dependence, and withdrawal symptoms, coupled with a loss of control over use, are signs of addiction.
