The effects of Dexedrine are determined by numerous factors, such as body weight, other medical conditions, and other medications. Dexedrine come as either short-acting (usually 4 hours) or long-acting (6-12 hours) tablets. The shorter-acting medications effects take place in 20 minutes, while the longer-acting ones may take up to an hour before the effects begin to take place.

Hundreds of animal studies and human clinical trials leave no doubt about how Dexedrine effects work. First, Dexedrine suppress all spontaneous behavior. In healthy chimpanzees and other animals, this can be measured with precision as a reduction in all spontaneous or self-generated activities. In animals and in humans, this is manifested in a reduction in the following behaviors: (1) exploration and curiosity; (2) socializing, and (3) playing. Second, Dexedrine increase obsessive-compulsive behaviors, including very limited, overly focused activities.
