Psychoactive drugs are usually broken down into four categories: depressants, stimulants, opioids, and hallucinogens. Depressants, including, alcohol, barbiturates, and benzodiazepines, decrease consciousness by increasing the production of the neurotransmitter GABA and decreasing the production of the neurotransmitter acetylcholine. Alcohol, a depressant psychoactive, slows down brain activity by increasing the activity of GABA neurotransmitters. Examples of psychoactive drugs and substances include alcohol, caffeine, nicotine, marijuana, and certain pain medicines.

Opioids, though, also release high levels of dopamine, leading to the intense feelings of euphoria and pleasure caused by other drugs. Some of the dangers of psychoactive drugs include: Short-term physical effects include higher blood pressure, rapid heartbeat, problems with sleeping and eating, nausea and vomiting, shakiness, or dizziness. They cause changes in a person's mood, behavior, and awareness (like time and space). 1. Most CNS depressants act on the brain by increasing activity of gamma-aminobutyric acid (GABA), a chemical that inhibits brain activity. Over time this can lead to brain damage. The high is generally fairly short-lived, however, and cocaine is often abused in a binge pattern to try and extend the euphoria. The hallucinogens may produce striking changes in perception through one or more of the senses. B., Ramsey, S. E., Stuart, G. L.,Brown, R. A. Alcohol is an intoxicating ingredient found in beer, wine, and liquor that acts as a depressant to the central nervous system. Nicotine is the main cause for the dependence-forming properties of tobacco use, and tobacco use is a major health threat. The American Journal of Drug and Alcohol Abuse, 32(2), 275285. With each pump the balloon appears bigger on the screen, and more money accumulates in a temporary bank account. However, when a balloon is pumped up too far, the computer generates a popping sound, the balloon disappears from the screen, and all the money in the temporary bank is lost. Ben Amar, M. (2006). When a person uses them, it causes changes in how the brain responds to stimuli. In recent years, cannabis has again been frequently prescribed for the treatment of pain and nausea, particularly in cancer sufferers, as well as for a wide variety of other physical and psychological disorders (Ben Amar, 2006).

What is the Common Comorbidity in Substance Abuse? Effects of alcohol on human aggression: Validity of proposed explanations. In small to moderate doses, barbiturates produce relaxation and sleepiness, but in higher doses symptoms may include sluggishness, difficulty in thinking, slowness of speech, drowsiness, faulty judgment, and eventually coma or even death (Medline Plus, 2008).

On the other hand, drugs that are normally associated with addiction, including amphetamines, cocaine, and heroin, do not immediately create addiction in their users. Nicotine, alcohol, and caffeine are all types of psychoactive substances that people frequently consume. In their research they compared risk-taking behavior in adolescents who reported having tried a cigarette at least once with those who reported that they had never tried smoking. Learn how to recognize the signs of an opioid overdose. Opioids, including codeine, opium, morphine and heroin, produce euphoria and analgesia by increasing activity in opioid receptor neurons. The effects of all psychoactive drugs occur through their interactions with our endogenous neurotransmitter systems. Typically, you feel better, more alert, or relaxed.

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. Psychoactive drugs are drugs that affect the Central Nervous System, altering its regular activity. Cocaine, methamphetamine (meth), and prescription amphetamines, such as those used to treat attention deficit hyperactivity disorder (ADHD) like Adderall (amphetamine/dextroamphetamine) and Ritalin (methylphenidate) are classified as stimulant drugs. Three main mechanisms of action of caffeine on the central nervous system have been described. In North America, more than 80% of adults consume caffeine daily (Lovett, 2005). First of all, cocaine stimulates the release of dopamine into the empty spaces between neurons, essentially flooding the brain with this neurotransmitter. Impaired coordination, learning issues, and sleep problems can result from long-term marijuana use and its impact on the brain.
