- Humans have always sought to expand
experience: Aphrodisiacs, Spirituality, Knowledge of "Other Worlds."
- Plants have been there to help
- Knowledge of appropriate ways
to use plants to achieve particular effects has been part of human culture(s)
for 1000's of years
Ancient
Religions
- Earliest form of religious
expression: Animism
- Spirits are thought to inhabit:
animals, plants, rocks, etc.
- Consume the object and "inherit"
the spirit: Communicate, Special Powers, Knowledge
- Medicine Man, Shaman: Specialist
in plant properties
- Plants and their psychoactive
properties were instrumental in the development of human religions and folklore.
- Psychedelics
and Religious Experience
What's
in a Name?
- 1931: Category of drugs associated
with the world of fantasy referred to as Phantastica
- 1960's: Psychedelic. Mind
made manifest, "See" more clearly, Transcend cultural limitations.
Aldous Huxley "The Doors of
Perception" (1954). Direct confrontation with reality.
Humphrey Osmund: LSD as a drug with "more than medical
significance." Pro-drug ideology.
- Impact of these drugs: Hallucinations,
Psychotic-like experience=> Psychotomimetic. Induced state is illusion
and undesirable. Anti-drug Ideology. Hallucinogen
- Psycholytic: A substance
that is useful in a therapeutic
setting.

General Categories of Hallucinogens

Indole Hallucinogens
- Substances which contains the
"indole nucleus" which is the basic structure of the neurotransmitter
Serotonin (impact on deep sleep regulation).
- The individual is typically able
to maintain some contact with the "real" world and remember the
experience.
- Little "acute physiological
toxicity," overdose deaths unlikely.

LSD
LSD-25
(this .zip file is a program to download (it will need to be unzipped!) that
will give you a taste of the experience! Contact viehland@umr.edu
for more information.
- Lysergic
Acid Diethylamide (the "S" comes from the German word
for acid: Saure)
- Odorless, colorless and tasteless
- LD50 (rats) is about 400x the
ED
- Dose for recreational purposes:
1965-79: 150-250 micrograms, Today: 25-100 micrograms (see, LSD
Samples Analysis)
- Stable use patterns (rather than
"comeback")
- Early years: Key to mind expansion;
Today: "Just another drug in the soup"
- Not found in nature, Semi-synthetic:
synthesized from the ergot alkaloids from the ergot fungus Claviceps
purprea. Mold which grows on grain, typically rye. Causes illness:
ergotism (ergot
timeline). The following is from a 2/15/2000 post the MAPS Discussion
list:
In addition to ergotamine
and dihydroergotamine which are used in the treatment of migraines, the
ergot alkaloid methylergonovine is an obstetric agent used to induce labor
and to control excessive uterine bleeding. (I believe these are its
main uses; Im a psychiatrist so thats not the usual end of the
body that I treat.) Also, if Im not mistaken, Hydergine (ergoloid
mesylate) is also a related compound believed by some to improve cognitive
ability.
The ergot preparations
used in migraine therapy are potent vasoconstrictors and are metabolized
in the liver by a specific subset (3A) of metabolic enzymes (known as the
cytochrome P450 system). Among the antiretroviral protease inhibitors, ritonavir
and indinavir are particularly potent inhibitors of the cytochrome P450
3A subset (among others). I have run across 3 case reports in which migraine
treatment with ergotamine resulted in severe systemic vasoconstriction when
co-administered with indinavir or ritonavir. According to the PDR, "ergotamine
overdose [may] include the following: numbness, tingling, pain, and cyanosis
of the extremities associated with diminished or absent peripheral pulses;
respiratory depression; an increase and/or decrease in blood pressure, usually
in that order; confusion, delirium, convulsions, and coma; and/or some degree
of nausea, vomiting, and abdominal pain." For dyhydroergotamine the
maximum recommended dose is no more than 4mg administered intranasally over
the course of 7 days (in 0.5mg doses) and for ergotamine no more than 10mg
(in 1mg doses) over the course of a week. Overt ergotism is rare but apparently
may be precipitated by the inhibition of hepatic metabolism of these 2 drugs.
I have found no references
to adverse reactions to Hydergine or methylergonovine in combination protease
inhibitors or other cytochome P450 inhibitors (two common examples being
nefazodone and erythromycin). Additionally there are no reports of adverse
reactions to LSD in individuals taking cyp3A inhibitors. Appologies for
the confusion regarding which drugs I was referring to in the phrase "these
agents" near the end of my previous post.

sheet on LSD
. LSD has a way of "doing that!"
- Magic
Mushrooms
- Used by natives of South, Southwest
and Central America(s)
for centuries
- Teocanacatl: "God's
flesh" or "sacred mushroom"
- "Rediscovered" in 1930:
many species identified
- NY banker/ethnobotanist, Gordon
Wasson, first outsider to participate
"It permits you
to travel backwards and forward in time, to enter other planes of existence.
Even (as the Indians say), to know God..."
- Psilocybe mexicana
is species with greatest psychoactive effect. Psilocybin is primary
active ingredient; isolated and synthesized by Albert Hofmann (LSD) in 1958.
- Dried mushrooms: .2-.5%, psilocybin--
similar to LSD
- Effects: up to 4 mg.: pleasant,
relaxing, "body trip"
- Higher doses: perceptual changes,
distortion of body image and hallucinations
- CNS effect after changed to
psilocin: little in mushroom, half as potent. Psilocybin's higher
lipid solubility is linked to its greater psychoactive properties.
- "Good
Friday Study": Tim Leary's follower- investigate as tool to induce
religious experience. 20 seminarians, double blind study, half placebo, 90
minutes prior to religious ceremony. Immediate, one week, and 6 month follow-up.
- Can grow in a closet. Spores available
through mail order.
- Use seems to be stable, popular
in the 1990's. Availability is rather sporadic.
- Mexico: ololiuqui, seeds
of the morning glory plant, Rivea corymbosa.
- Alkaloids similar to LSD, especially
d-lysergic Amide, about 1/10 as active as LSD(Albert Hofmann, again), 1960.
- This finding relating to Morning
Glory's is unique since lysergic acid had only been known to exist in the
ergot fungus
- In USA, the species Ipomoea
violacea is most common.
- Seeds are eaten in large numbers
to achieve the psychedelic effect. CAREFUL!! Seeds are coated with a poisonous
herbicide.
- Names of commercial varieties:
Pearly Gates, Flying Saucers, Heavenly Blue.
- Dimethyltryptamine. Also a variant-
DET and DPT
- Not widely used in USA
- But, most important, naturally
occurring hallucinogen (neurotransmitter). Occurs in a wide variety of plants.
- Cohoa snuff: S. America and Caribbean.
- Must be snuffed, smoked, or injected.
- Short duration, ~30-60 minutes:
"Businessman's Trip"
DrugsText Information
on DMT


Catechol Hallucinogens
- Similar to indole hallucinogens
- But, different chemical structure:
catechol nucleus, basic structure of the catecholine neurotransmitters; norepinephrine
and dopamine (waking response, REM sleep, and reward centers)
- Also, similar to amphetamines,
although the stimulant effect is not as pronounced.

- Peyote cactus: Lophophora
williamsii. Small, spineless cactus. Subterranean. Rio Grande Valley
and southward. Grayish-pink pincushion like top protrudes above the ground.
(Flowering
Peyote)
- Crown is sliced into disks: peyote
buttons or mescal buttons
- Not the same as mescal beans or
mescal liquor: these come from the agave cactus- contain another alkaloid,
cytisine- highly toxic, effects resemble nicotine.
- Peyote:
The Divine Cactus
Pharmacology
- Taken orally=> readily absorbed
- High doses required: passes blood-brain
barrier poorly
- Reaches highest concentration
in 30-120 minutes, half removed from body in 6 hours, although some persists
in brain for up to 10 hours.
- Low doses: euphoria; High doses:
Hallucinations.
- Excreted unchanged in the urine,
metabolites not psychoactive.
- Objective effects: dilated pupils,
increase pulse and BP, body temperature elevated. Also elevated EEG activity.
LD50 is about 30x effective dose. Death: convulsions and respiratory depression.
Tolerance develops, and cross-tolerance with LSD.
- Although different chemical structure,
appears to operate similar to LSD. Effects blocked by serotonin antagonist.
- Evidence as early as 1760 of use
in USA, yet wasn't until late 19th Century that peyote cult was widely established.
- Today, perhaps 250,000 members.
Cross between Christianity and traditional tribal beliefs. Native American
Church chartered in Oklahoma in 1918.
- Peyote used as aid to prayers,
as medicine, and worn as an amulet.
- Use was protected for many years.
(Leary attempted to have LSD recognized as "sacramental" for the
1960's "The League for Spiritual Discovery").
- 1990 Supreme Court ruled state
of Oregon could prosecute its use. Religious freedom not allowed as counter
argument.
- Federal law and many states specifically
exclude sacramental use of peyote from prosecution, but the court allows individual
states to outlaw.
- Further decisions: "Wait
and see."
- June 2004: "Utah
Supreme Court ruled that peyote use in "bona fide" religious ceremonies,
regardless of the race of the participants, is protected under Utah and Federal
Law in Utah. " (Erowid)
(Peyote Leagl
Status)
Non-Religious Use
- Mescaline isolated as primary
psychoactive agent in peyote in late 19th Century: See: The Heffter Research Institute.
It was synthesized in 1919. It is now known to be one of 30 psychoactive
alkaloids in peyote.
- Early investigator: Dr Weir Mitchell,
"...what I saw.
Stars, delicate floating films of color, then an abrupt rush of countless points
of white light swept across my field of view, as if the unseen millions of the
Milky Way were to flow in a sparkling river before my eyes..."
- Huxley, in 1954, suggested both
the up side and down side of the mescaline experience.
- Availability and use limited today.
Often, what is sold as mescaline is a mixture of LSD and/or amphetamines.


Amphetamine derivatives
- Large group
of drugs, due to substitution on the ring of the catechol nucleus, effects
closer to mescaline than amphetamine.
- 2,5-dimethoxy-4-methylamphetamine
- AKA: STP (Serenity, Tranquility
and Peace)
- Similar in effect to mescaline
and LSD. 100x more potent than the former, 1/30 as potent as the latter.
- Trips reputed to be extremely
long, but due to the large doses consumed.
- Experience from the Haight-Ashbury
Clinic suggest high incidence of toxic effects

MDA
(see also DrugText for additional
information)
- Wide variety of concoctions here,
also DOET, TMA-2.
- Similar to above in effects, although
MDA seems to be subjectively different
- Designer Drugs

Anticholinergic Hallucinogens
- Potato Family: Solanaceae
- Three genera: Atropa, Hyoscyamus,
Mandragora (Europe); and one worldwide: Datura
- Atropine,
Scopolamine and l-hyoscyamine
- These drugs occupy, but don't
activate, the acetylcholine receptor site. They have both peripheral and central
effects: Mucous, saliva, and perspiration levels drop; heart rate decreases;
body temperature increases; pupils dilate (difficulty focusing). High doses:
confusion, toxic psychosis. No vivid sensory effect.
- Deadly nightshade (atropine)
- Used as a poison throughout the
Middle Ages and before.
- Name refers to "beautiful
woman": dilation of pupils. Used by Roman and Egyptian women. Today we
know that people judge a woman with more dilated pupils to be "pretty."
- Witches and "flying":
Prepare ointment, rub between legs and on stick (phallic symbol)- suggested
as part of the ritual of the Sabbat, or Black Mass
- Significant mention throughout
history, especially: Bible
- Close association with love and
lovemaking
- Root resembles the human form
- Very active
- Used primarily as poison
- Used to "poison" Hamlet's
father
- Ancient Chinese: medicinal use-
for colds
- Associated with the "Buddha"
- Greeks: Delphi Oracle-- "Know
Thyself"
- India: Shiva- love potions
- S.W. American Indians
- Algonquin Indians: Adolescent
identity search
- Jamestown: Jimsonweed- Early Spring
growth, salads- strange behavior
Synthetic Anticholinergics
- Used previously to treat Parkinson's
disease (now L-DOPA)
- Still used for pseudoparkinsonism
- Fly agaric: When flies ingest
the juice-- stuporous for 2-3 hours
- Common poisonous mushroom
- Severe effects: twitching,
raving drunkenness, vivid hallucinations
- Aryan invaders into India--
3500 years ago: Soma, sacramental substance. Discover within the past 25 years
to be Amanita.
- Ambrosia- fruit of the god
Dionysious
- Even suggested, based on the
paintings representing the "tree of life" found in Roman catacombs,
that this mushroom formed a basis for a cult 2000 years ago which now goes
by the name Christianity.
(local copy) See,
Allegro, J. (1970). The Sacred Mushroom and the Cross: A Study of the Nature
and Origins of Roman Theology within the Fertility Cults of the Ancient Near
East. London: Hodder and Stoughton.
More at wikipedia.
Most scholars are a bit skeptical of Allegro's claims.
- Until Russians brought alcohol,
tribes of Siberia had no other intoxicant, its use continues today: Cost-
several reindeer for an effective dose.
- Psychoactive agent is excreted
in the urine and is "reusable"
- Use also associated with several
native American tribes
- Originally the psychoactive
agent was thought to be muscarine: similar to the anticholergics. But,
now Bufotenin.
Also found as secretions on certain toads (genus Bufo). TOADLICKING: an
urban legend. Not a very potent hallucinogen, and toads have a variety of
other toxins. Oakley Ray cautions: "Don't lick strange toads, and be
particularly cautious about believing weird stories about hallucinogenic drugs."
Actually, it's the venom that is harvested, dried, and smoked. See: http://www.bouncingb.com/bufo_alvarius.php.
- More recent studies: two other
chemicals in the Amanita: ibotenic acid and muscimol.
- Effects strange and different.
Confusion, disorientation in time and space, sensory disturbances, twitching,
fatigue and sleep.
- Parke, Davis and Co. In the
1950's: New intravenous anesthetic-- Phencyclidine.
- Not a very good product, but
animals did seem to become "disassociated"
- Use in humans: unpredictable
psychological effects-- feelings of unreality, depersonalization, persecution,
depression, and intense anxiety.
- By 1960: seen as useful as
anesthetic for animals; medically safe, but problematic for humans; and a
hallucinogen of a "different sort."
- Used in veterinary medicine
to "stun" animals (not a tranquilizer)
- Similar drug marketed: Ketamine
- Appears on the streets- late
1960's-1970's: "Hog," "garbage," "Angel Dust."
- Use to "beef" up
poor quality marijuana, sold as a substitute for just about everything
- Morgan and Kagan: Media myths
and realities. Dangerous, yes- But: with each "new" drug explosion
of negative publicity feed itself to create overblown vision of danger. Use
and "morbidity of PCP declining. Culture has "adjusted."
- Most news coverage on PCP in
aone year: 1978. Narrow focus on individual cases--issuesof violence and horror.
Media "myth" becomes (and remains) popular image.
- Linked to violence, yes, but
level of use is minimal
- 2000 DAWN: .33% of ER cases.
Even in 1970, 20 million instances of use; 6,000 trips to ER.

Subjective
effects
- Eidetic Imagery: "Eyeball

- Synesthesia
- Multi-level Reality: multiple
perspectives, molecular view, universal images.
- Fluidity
- Subjective Exaggeration:
Number, Size, Details and
Transformation of objects
- Emotional Lability: ups and downs
- Timelessness
- Irrationalism: intuition, organicism.
Words, meanings become strange. Impact of subcultural attitudes and rejection
of Western culture.
- Pseudo-hallucinations
- Ambivalence
- Sensory overload
- "Flashbacks" (chronic
subjective?)
Objective
Effects
- Metabolized rapidly- 4 hour
half life
- Tolerance develops rapidly, cross
tolerance.
- No physical addiction or dependence.
- Dilated pupils
- Elevated body temperature, BP,
salivation.
- ASC effects: serotonin systems
of the brain.
- Panic reactions
- Prolonged psychotic reaction
Latter two seem to
reflect use patterns and subcultural controls. As use has remained consistent,
perhaps even slight increase; problems associated with use have decreased.

Becker on Subculture
- Over time the
subculture develops interpretations of drug experience, these take the experience
out of the realm of insanity and place it in a "normal context.
- Creates approved and rational
status
- Ideology of acceptance, and positive
nature
- Sets expectations
- Leads to fewer problems today,
coupled with lower doses
- Zinberg
on controlled use.
Goode
- All users have bad experiences
- Most handle
- Importance of "cultural context"
for interpreting experience: Middle Ages and ergotism
- Definitions of reality; cultural
"openness."
- Many cultures successfully integrate
the drug experience into the realm of normalcy and acceptability.
- For pure
LSD- Actual number of "bad" experience small (Joel Fort- 1:1000);
seriously bad- 1:10,000. BUT: Street
acid?????
- Why risk? Problems can occur,
but are unlikely for stable individual. Still there is the potential for permanent
damage. Significant: YES; Typical: NO.

Chronic Objective
Effects
- 1967: Chromosome breaks. Tetragenesis
(leads to birth defects). Thalidomide scare.
- Heavy Press coverage, distortions:
"Acid Burned a Hole in My Genes"
- Problem of controls in the
studies: Street vs Pure drug; Frequency and dosage levels, Other drugs, Animal
studies vs. Humans
- And, chromosome breakage does
not mean birth defects: "normal" rate is about 4%. Question is,
is the rate significantly higher for mothers who take LSD. And, when did she?
First trimester is most critical
- Major studies suggest that
impurities in street acid seem to explain problems.
- Mutagenesis is related to massive
doses, Pure LSD does not appear to be significantly related to birth defects
- Politics and Ideology
- In 2000, LSD accounted for
.01% of DAWN ER cases
- Subcultural
change, as well as media hype.
- Yet, early media attention
was instrumental force in passing Drug Abuse Control Act of 1966 (which leveled
controls on LSD). By 1970: Controlled Substances Act.

Use Patterns
- Media and some researchers
view peak in late 1960's: ?? "Leary Phenomenon" ??
- Media coverage certainly peaks
in an eleven month span, March 1966- February 1967, BUT:

- The slight increases in persons
reporting lifetime use of LSD from the late 1990s has stabilized, figures
on all hallucinogen use have remained fairly stable.
- : Little
frequent, chronic use. User loyalty
- LOW "sensuous appeal"--
animals will avoid.
- Why no dependence or chronic
use?... Tolerance develops rapidly, use requires a lot of effort-- it's physically
exhausting (Like study of professional's use of XTC: can't do other things);
Effects are inconsistent.
- Massive revival: Unlikely
CNS
Stimulants: Xanthines, Amphetamine, Nicotine, and Cocaine
