This can result in impaired motor functions, auditory and visual distortions, memory loss, anxiety, numbness, and body tremors. Like all psychoactive drugs, which affect the central nervous system, stimulant medications are designed to penetrate the blood-brain barrier - the specialized tissue and blood vessels that . 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.

The most common psychoactive drugs can roughly be divided into four groups: Depressants, such as alcohol, sedatives/hypnotics and volatile solvents, that diminish the activity of the central nervous system.

Heroin and prescription opioid drugs like OxyContin (oxycodone), Vicodin (acetaminophen/hydrocodone), fentanyl, methadone, and Dilaudid (hydromorphone) bind to opioid receptors in the brain and trigger the release of dopamine. Cocaine and meth, especially, produce an intense high as they rapidly flood the brain with dopamine. Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. In order to sustain the high, the user must administer the drug again, which may lead to frequent use, often in higher doses, over a short period of time (National Institute on Drug Abuse, 2009).

Stimulants may cause someone to feel a sense of euphoria, excitement, or increased energy.

Depressants, including, alcohol, barbiturates, and benzodiazepines, decrease consciousness by increasing the production of the neurotransmitter GABA and decreasing the production of the neurotransmitter acetylcholine. Effects of alcohol on human aggression: Validity of proposed explanations. Depressants can make people feel sleepy, relaxed, or calm. Gable, R. (2004).

The drugs that produce the most extreme alteration of consciousness are the hallucinogens, psychoactive drugs that alter sensation and perception and that may create hallucinations. Because they cause a persons breathing to slow, misusing them can cause hypoxia, when the brain does not get enough oxygen. It can also lead to severe complications, including heart attacks and sudden death, potentially with a persons first use. Concurrent use of cocaine and alcohol is more potent and potentially more toxic than use of either aloneA multiple-dose study 1. Central nervous system depressants are used to treat a number of different disorders, including: insomnia, anxiety, panic attacks, stress, sleep disorders, pain, and seizures.
