Psychoactive drugs are substances that, when taken in or administered into one's system, affect mental processes, e.g. Cocaine effects on the central nervous system include: Sleeping problems Seizures Breathing problems Change in heart rate Increased blood pressure Loss of smell Paranoia Hallucinations Movement disorders (Parkinson's disease) Loss in gray matter Caffeine is a naturally occurring central nervous system (CNS) stimulant of the methylxanthine class and is the most widely taken psychoactive stimulant globally. The American Journal of Drug and Alcohol Abuse, 32(2), 275285. Marijuana also interferes with levels of dopamine in the brain, causing the euphoric high that users document. Higher doses of this drug can cause a person to experience erratic behaviors, including violence, anxiety, panic, and paranoia. In some people, MDMA may also have stimulant or hallucinogenic effects. 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. In North America, more than 80% of adults consume caffeine daily (Lovett, 2005). Psychoactive drugs may be legal prescription medications (e.g., codeine and morphine), legal nonprescription drugs (e.g., alcohol and tobacco), or illegal drugs (cocaine and LSD).

It can make someone feel calm, relaxed, or euphoric. They are synthetic compounds introduced into medicine to produce an anesthetic loss of sensation without depressing respiration and cardiovascular function as do the general anesthetics. The participants were tested in a laboratory where they completed the Balloon Analogue Risk Task (BART), a measure of risk taking (Lejuez et al., 2002). Psychoactive drugs create negative effects not so much through their initial use but through the continued use, accompanied by increasing doses, that ultimately may lead to drug abuse. In addition to the drug's primary effects on behaviors such as arousal, thought processes, mood, perception, and consciousness, psychoactive drugs can produce a variety of nonbehavioral effects that may more directly affect health and, in some instances, can lead to death.

Heroin is considered the fastest-acting opioid, taking effect nearly immediately and making it extremely addictive, the Drug Enforcement Administration (DEA) warns. Addiction is a common problem in many countries. The brain will then stop functioning as it did before introduction of the opioid, causing levels of dopamine to drop when the drug wears off. The use of psychoactive drugs, and especially those that are used illegally, has the potential to create very negative side effects (Table 5.1 Psychoactive Drugs by Class). The effects of all psychoactive drugs occur through their interactions with our endogenous neurotransmitter systems. Do people you know use psychoactive drugs? Although alcohol is not illegal for . Because of the way psychoactive drugs affect brain function, there are changes in perception, mood, consciousness, cognition and behavior [4,5]. This drug delivery platform can be used to treat cancers in the brain and other sites of the body, as well as other inflammation-related diseases in the central nervous system and elsewhere. Examples of depressants include alcohol, opioids (including prescription drugs such as morphine and street drugs like heroin), and tranquilizers. Psychology of Women Quarterly, 20(1), 147169. Opioid drugs also disrupt the natural production of norepinephrine and act as central nervous system depressants. However, it can also reduce a persons ability to think rationally and lead to impaired judgment. Injecting or smoking cocaine produces a faster, stronger high than snorting it. Breathing and respiration problems, chronic cough, and bronchitis are additional possible consequences of chronic marijuana smoking. This method of drug use provides the highest intensity and quickest onset of the initial rush but is also the most dangerous. Because they cause a persons breathing to slow, misusing them can cause hypoxia, when the brain does not get enough oxygen. In fact, roughly 80% of adult Americans consume caffeine daily.

Respond in an appropriate manner to the sensory inputs. Today cocaine is taken illegally as recreational drug. It can also lead to severe complications, including heart attacks and sudden death, potentially with a persons first use. MDMA also affects the temperature-regulating mechanisms of the brain, so in high doses, and especially when combined with vigorous physical activity like dancing, it can cause the body to become so drastically overheated that users can literally burn up and die from hyperthermia and dehydration. Combining drugs is dangerous because their combined effects on the CNS can increase dramatically and can lead to accidental or even deliberate overdoses.

Hallucinogens like mushrooms, LSD, DMT, and ayahuasca affect the brain differently. The BART is a computer task in which the participant pumps up a series of simulated balloons by pressing on a computer key. 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. Alcohol, a depressant psychoactive, slows down brain activity by increasing the activity of GABA neurotransmitters. The hallucinogens may produce striking changes in perception through one or more of the senses. Over 2.5 million Americans battled opioid addiction in 2015. Journal of Ethnopharmacology, 105, 125.
