Amphetamine - Wikipedia, the free encyclopedia

Psychological
Common psychological effects of therapeutic doses can include alertness, apprehension, concentration, decreased sense of fatigue, mood swings (elevated mood or elation and euphoria followed by mild dysphoria), increased initiative, insomnia or wakefulness, self-confidence, and sociability.[24][28] Less common or rare psychological effects that depend on the user's personality and current mental state include anxiety, change in libido, grandiosity, irritability, repetitive or obsessive behaviors, and restlessness.[ref-note 6] When heavily abused, amphetamine psychosis can occur.[13][24][25] Although very rare, this psychosis can also occur at therapeutic doses during long-term therapy as a side effect.[13][24][26] According to the USFDA, "there is no systematic evidence that stimulants cause aggressive behavior or hostility."[24]

Dependence, addiction, and withdrawal
Addiction is a serious risk with heavy recreational amphetamine use, but is unlikely to arise from typical medical use.[13][27][28]
Tolerance develops rapidly in amphetamine abuse, so periods of extended use require increasing doses of the drug in order to achieve the same effect.[62][63]
A Cochrane Collaboration review on amphetamine and methamphetamine dependence and abuse indicates that the current evidence on effective treatments is extremely limited.[64] The review indicated that fluoxetine[note 8] and imipramine[note 9] have some limited benefits in treating abuse and addiction, but concluded, "no treatment has been demonstrated to be effective for the treatment of amphetamine dependence and abuse."

So you are sure that you, a person who has never tried any narcotic in your life, would know that your condition of "alertness, apprehension, concentration, decreased sense of fatigue, mood swings (elevated mood or elation and euphoria followed by mild dysphoria), increased initiative, insomnia or wakefulness, self-confidence, and sociability" is a consequence of a drug intoxication or it's just because of your your susceptibility to the psychological atmosphere of a great mass of people? No, you'll notice that something wrong only when narcotic withdrawal begins.
