"A brain structure largely ignored by drug addiction researchers
may play an important role in producing the similar ill effects
of amphetamine and cocaine binges, including hallucinations and 
gradually worsening paranoia, according to a report accepted for 
publication in BRAIN RESEARCH. If the findingd hold up, they may
lead to a new theory of how disturbances involving the chemical
messenger dopamine promote various types of psychosis, asserts
psychologist Gaylord Ellison of the University of California, Los
Prior animal research has found that taking amphetamine for several
days damages dopamine-rich cells in a brain area called the caudate,
while comparable cocaine intake leaves the caudate unscathed. However,
these studies often rely on daily drug injections that fall far short
of the "speed runs" of human addicts, who may consume cocaine or am-
phetamine every few hours for days, Ellison notes.
He and his co-workers developed slow-release silicone pellets that,
when implanted under the skin, deliver continuous doses of either
amphetamine or cocaine for five days.
Rats implanted with amphetamine pellets, but not those bearing cocaine
pellets, display caudate damage by the third day, based on staining and
microscopic analysis of their brains. However, both groups suffer ex-
tensive damage to a structure near the center of the brain, the habenula,
and its cell connections to a related region, Ellison contends.
Anatomical studies indicate that the habenula helps to regulate dopamine 
transmission by slowing its release elsewhere. The habenula also
maintains connections to cells that produce serotonin, a chemical
courier involved in hallucinations, Ellison holds. Destruction of cell 
pathways linking the habenula to other brain structures may at least
partly cause amphetamine and cocaine psychosis, he proposes."

My excellent book: "Drugs and the Brain" by Solomon H Snyder (a fellow tripper)
contains the following factoids about Ephedrine

Ephedrine was discovered by K. K. Chen, who was looking for a substitute for 
Adrenalin as an antiathsmatic (sp?).  Chen was curious about chinese herbal
medicine, in particular ma huang.  He and other Lilly chemists quickly isolated
ephedrine, and verified that it widened bronchial passages.  Since Adrenalin
couldn't be taken orally, and had a hell of a side-effect :-)  ephedrine
seemed vastly preferable.  The rarity of ma huang quickly sent chemists 
scrambling for a synthetic ephedrine, and sometime in the 30's, one of them
stumbled on Amphetamine.

Amphetamine was also a bronchiodilator, and could be inhaled directly, 
delivering the relief within seconds.  It was marketed under the name 
Benzedrine and quickly became a legal, over the counter, recreational drug.

..from a 1937 Journal of the American Medical Association
"Benzedrine Tablets were used at the department for Psychology at the 
University of Minnesota to study ... effects on human thought.  It was
found that the substance increased alertness...  Apparently, the effect
iveness of the drug in delaying the onset of sleep has induced many 
University of Minnesota students so seek the drug in local Pharmacies."

Anyhoo.  Ephedrine is structurally similar to the family of Amphetamines,
so it's concievable that it could serve as a precursor.  this is probably
reason enough for the Feds to clamp down on it....Stock up now.
