What are the central nervous system stimulants?

Central nervous system (CNS) controls the functioning of the whole body. The central nervous system stimulants are medicines or substances that stimulate or excite the central nervous system, providing the user with increased energy, increased mood and increased alertness. Some stimulants such as caffeine and ginseng are available at the counter. Others, such as amphetamines, are available on the basis of a regulation and others such as cocaine, are not approved in some countries for legal use. Stimulants can increase heart rate, blood pressure and body temperature. The effects of caffeine are typical of most stimulants: the user can feel up, more energetic and may have an increased ability to concentrate. However, high caffeine intake can excessively stimulate the central nervous system, produce fatigue, shock and concentration.

There is a Wide variety of psychoactive drugs that act as strong central nervous system stimulants. Examples of these stimulants or "upper" arecocaine, methamphetamine, ecstasy and amphetamines. These substances are generally not approved for legal use and are considered illegal, recreational drugs. Stimulants can be snorted with a nose, smoked, swallowed or injected directly into the bloodstream. The use method depends on a specific drug. For example, cocaine is commonly in a powder form that is snorted with a nose, while ecstasy is usually swallowed in the form of a pill.

Some amphetamines are available in the form of a prescription and have a medical therapeutic application. These prescription drugs, such as methylphenidate (Ritalin®), are often used to treat hyperactivity disorder with attention deficit (ADHD). In carefully regulated doses, these drugs on the TNERV system have made patients more vigilant and concentrated better. Recreational use of such drugs is strongly discouraged because the habit may form and overdose can cause vomiting, seizuresand loss of consciousness. If a patient is experiencing any of these symptoms, even if he takes the prescribed dose, he should be immediately transported to the standby room.

Central nervous system stimulants usually act quickly on the brain, causing a large amount of chemical dopamine that causes a sense of pleasure. This increase in dopamine often causes euphoria and intense pleasure, but can also create anxiety and restlessness. Stimulants differ from depressive substances and hallucinogens that create a changed mood by chemical reactions with cerebral chemical or neurotransmitter called serotonin.
