Afterglow is usually used to refer to the positive mental and physical effects that someone experiences after the original effects of a drug have subsided. Typically, this term is used in association with hallucinogens, including psychedelics. Individuals typically have more energy and feelings of freedom during an afterglow. Some of the most common experiences include an increased state of confidence, a feeling of relaxation, difficulty falling asleep, and a feeling of being clean. Not every drug causes an afterglow, but drugs that lead to an afterglow typically lead to these effects after the comedown phase. Individuals who experience an afterglow often describe a mystical or transcendental experience that cleanses them of negative energy and causes them to feel more alive.
