The physiological and psychological symptoms of amphetamine withdrawal are well-documented and recognized clinical facts, requiring no citation.
The claim that amphetamine withdrawal produces physiological and psychological symptoms is a standard medical and psychiatric fact regarding stimulant dependence. None of the retrieved papers specifically target amphetamine withdrawal; they discuss unrelated conditions such as bipolar disorder, post-COVID syndrome, skin kinetics, CADASIL, substance use disorders generally, ADHD, and fibromyalgia. Because this is a matter of established textbook knowledge, it is classified as common knowledge.
