Psychoactive drugs are usually broken down into four categories: depressants, stimulants, opioids, and hallucinogens. . 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.

(2002). These are neurotransmitters that bind to receptors in our peripheral nervous system and central nervous system. In a sense, these drugs hijack the limbic system in the brain, inducing a powerful high that individuals are often keen to recreate, leading to reinforcing behaviors. Mind-altering drugs may slow down or speed up the central nervous system and autonomic functions necessary for living, such as blood pressure, respiration, heart rate, and body temperature. Their chemical makeup is similar to the endorphins, the neurotransmitters that serve as the bodys natural pain reducers. Natural opioids are derived from the opium poppy, which is widespread in Eurasia, but they can also be created synthetically. Alcohol, barbiturates, and benzodiazepines are central nervous system depressants that affect GABA neurotransmission. These substances can affect awareness, thoughts, mood, and behavior.

Although the level of physical dependency is small, amphetamines may produce very strong psychological dependence, effectively amounting to addiction. In 2018, more than 19 million adults in America had a substance use disorder (SUD). Caffeine is a naturally occurring central nervous system (CNS) stimulant of the methylxanthine class and is the most widely taken psychoactive stimulant globally. For people who do become addicted to drugs, the success rate of recovery is low. 1 They can affect concentration and coordination and slow down a person's ability to respond to unexpected situations. Ecstasy is also commonly combined with alcohol or other drugs, or cut with toxic substances, which can have potentially hazardous consequences. How do stimulant and depressant drugs affect the nervous system PCP interacts with dopamine as well, while salvia activates the kappa opioid receptor present on nerve cells, per NIDA. For example, cocaine is a stimulant that supercharges the central nervous system. These slow down the central nervous system, having an impact on both mental and physical activity. As tolerance increases, so does the risk of drug dependency, addiction, and withdrawal. Depressants inhibit the CNS, increasing the activation of the GABA neurotransmitter.

Caffeine and the central nervous system: mechanisms of action - PubMed New Scientist, 2518. 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.
