Answer:
Amphetamine is a powerful psychoactive stimulant, used to threat patients with ADHD disorders. It is also used illegaly as a stimulant.
Adderall is a ADHD medicine that contains a mixture of amphetamine and dextroamphetamine, both powerful stimulants which makes the user feel more energistic and focused, as well with a sense of well-being.
However, when illegaly abused they become incredible addictive; as tolerance builds up, so increases the consumption, that might lead to depression, anxiety and paranoia.
On the street amphetamine is usually cut with other adulterants such as; milk powder, glucose, talc and cement.
