Stimulants (also known as psychostimulants and colloquially as "uppers") are a class of psychoactive substances that activate the nervous system to increase alertness, arousal, and motor activity.[citation needed] Stimulants represent one of the three major classes of psychoactive substances: the other two are depressants (also known as "downers"), and hallucinogens. Primary effects include wakefulness, focus enhancement, appetite suppression, thought acceleration, ego inflation, and euphoria.

Stimulants exert their effects through a number of pharmacological mechanisms, the most prominent of which are increasing concentrations of the neurotransmitters dopamine and norepinephrine by either promoting release (e.g. amphetamine, methamphetamine) or by blocking reuptake (e.g. cocaine, methylphenidate). Prominent examples of dopaminergic stimulants include amphetamine, cocaine, methylphenidate, and methamphetamine. Some stimulants also have an additional significant effect on serotonin, such as MDMA, MDA, and mephedrone. These substances are sometimes separately categorized and referred to as entactogens.

Since their discovery in the early 20th century, stimulants have been adopted throughout the world as prescription medicines for attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity and illicitly as recreational substances.

Subjective effects

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠. These effects are listed and defined in detail within their own dedicated articles below:

Alongside of these a variety of non-essential secondary effects are often present. These generally include but are not limited to:

After effects

The effects which occur during the offset of a stimulant experience generally feel negative and uncomfortable in comparison to the effects which occurred during its peak. This is often referred to as a "comedown" and occurs because of neurotransmitter depletion. Its effects commonly include:
