Over time dependency occurs on these drugs. Like with coffee and people dependent on caffeine GRADUALLY over a long period of time their brains normal state develops an impaired ability to concentrate and focus. Many neurologists say that amphetamine derivatives* like adderall, pervitin, and amphedroxyn should not be taken for longer than a year.

Federer does not show absent mindedness nor various memory impairments that gradually develop from heavy caffeine dependency or amp-derivate* use.
