Amphetamines

Description

Amphetamines are a group of Pharmaceutical, illicit Recreational and Smart Drugs comprising Amphetamine and its derivatives (Amphetamine-Derivatives).  They are a sub-group of Phenethylamines.

Digestive System

 Amphetamines may cause Intestinal Permeability.  ^[1]

Immune System

 Excessive or long-term usage of Amphetamines may impair the Immune System (due to Norepinephrine deficiency interfering with the ability of the Thymus Gland to issue instructions to the Immune System).

Metabolism

 Excessive or long-term usage of Amphetamines may cause lack of Energy and lack of Motivation or Willpower (due to Norepinephrine and Vasopressin deficiency):

 Although Amphetamine may initially and temporarily increase Energy, Willpower and Motivation.

Nervous System

 Excessive or long-term usage of Amphetamines may cause Depression (due to deficiencies of Norepinephrine and Vasopressin):

 Although Amphetamines initially and temporarily alleviates Depression due to it causing the sudden release of large amounts of Norepinephrine and Vasopressin.

 Amphetamines may cause excessive stimulation of Dopamine D2 Receptors.

 Amphetamines may cause Drug Dependence.

 Excessive or long-term usage of Amphetamines may decrease Intelligence (due to depletion and destruction of Norepinephrine and Vasopressin):

 Although Amphetamines initially and temporarily increase Intelligence.

 Excessive or long-term usage of Amphetamines may impair Memory (due to Norepinephrine and Vasopressin depletion):

 Although Amphetamines may initially and temporarily improve Memory.

Enzymes

 Chronic usage of Amphetamines may suppress the endogenous production of Tyrosine Hydroxylase.

Neurotransmitters

 Amphetamines may cause the depletion of the Brain’s Dopamine.

 Chronic usage of Amphetamines may inhibit the endogenous production of L-Dopa (by suppressing the Tyrosine Hydroxylase enzyme, thereby preventing the conversion of Tyrosine to L-Dopa).
