A drug abuser who suffers long periods of time without sleeping or eating is likely abusing which type of drugs?

Stimulants often lead to increased energy levels and heightened alertness, which can result in long periods of wakefulness and diminished appetite. Users of stimulants, such as cocaine or methamphetamine, typically experience a burst of energy that may keep them awake and active for extended durations. This pattern of behavior is characteristic of stimulant abuse, as individuals may prioritize the use of the drug over basic physiological needs like sleep and food. Additionally, as the effects of the stimulant wear off, users might experience a crash that can lead to significant fatigue and further exacerbate their neglect of basic needs. This cycle makes it clear why individuals abusing stimulants are prone to such severe outcomes regarding sleep and nutrition.
