EDIT:
Here are the listed side-effects of this substance via wikipedia. Note they indicate which are from abuse and which are run of the mill.
Physical effects
Physical effects of amphetamine can include reduced appetite, increased/distorted sensations, hyperactivity, dilated pupils, flushing, restlessness, dry mouth, erectile dysfunction, headache, tachycardia, increased breathing rate, increased blood pressure, fever, sweating, diarrhea, constipation, blurred vision, impaired speech, dizziness, uncontrollable movements or shaking, insomnia, numbness, palpitations, and arrhythmia. In high doses or chronic use convulsions, dry or itchy skin, acne, pallor can occur.[33][34][35][36]
Occasionally amphetamine use in males can cause an odd and sometimes startling effect in which the penis when flaccid appears to have shrunk due to vasoconstriction. Upon erection the penis returns to normal size.[37]
Young adults who abuse amphetamine may be at greater risk of suffering a heart attack. In a study published in the journal Drug and Alcohol Dependence,[38] researchers examined data from more than 3 million people between 18 and 44 years old hospitalized from 2000 through 2003 in Texas. After controlling for cocaine abuse, alcohol abuse, tobacco use, hypertension, diabetes mellitus, lipid disorders, obesity, congenital defects, and coagulation defects, they found a relationship between a diagnosis of amphetamine abuse and heart attack.[39]
Psychological effects
Psychological effects can include euphoria, anxiety, increased libido, alertness, concentration, energy, self-esteem, self-confidence, sociability, irritability, aggression, psychosomatic disorders, psychomotor agitation, hubris, excessive feelings of power and superiority, repetitive and obsessive behaviors, paranoia, and with chronic and/or high doses, amphetamine psychosis can occur.[33]
Amphetamine use in adolescence may impair adult working memory.[40]
Withdrawal effects
Withdrawal from chronic use of amphetamine can include anxiety, depression, agitation, fatigue, excessive sleeping, increased appetite, short temper, psychosis and suicidal thoughts.[41]

In mid-February 2006 came the news that an advisory panel of drug-safety experts recommended a "black-box" warning for Adderall, Ritalin, and the other ADHD/ADD drugs -- and that the FDA was not going to act on this advice, at least for the time being. This situation left many people understandably confused.
