24. The Nature of Hallucinogens
Besides the traditional hallucinogens (such as LSD), high doses of anticholinergics, cocaine, amphetamines, and steroids can cause hallucinations

25. The Nature of Hallucinogens
These drugs most certainly influence the complex inner workings of the human mind and have been described as psychedelic, or psychotogenic psychotogenic are described as substances that initiate psychotic behavior

26. Sensory and Psychological Effects
In general, LSD is considered the prototype agent against which other hallucinogens are measured “A single trip,” or, more likely, will pass through only some. These states are as follows:
Heightened, exaggerated senses
Loss of control
Self-reflection
Loss of identity and a sense of cosmic merging

27. Sensory
Altered senses Loss of control Self-reflection Loss of identity and cosmic merging

28. Altered Senses
(Experience of Solomon Snyder)
After 30 minutes, some mild nausea
Objects took on purplish ting and appeared to be vaguely outlined. Colors, textures, and lines achieved an unexpected richness

29. Snyder Cont’d
Synesthesia- a subjective sensation or image of a sense other than the one being stimulated, such as an auditory sensation caused by a visual stimulus

30. Loss of Control
User will cannot determine whether the psychedelic trip will be a pleasant, relaxing experience or a “bad trip”
A bad trip can “replay” the frightening experiences at a later time. This is known as a “flashback”
Flashback- recurrences of earlier drug-induces sensory experiences in the absence of the drug

31. Self Reflection
User becomes aware of thoughts and feelings long hidden beneath the surface, forgotten and /or repressed

32. Loss of Identity and Cosmic Merging
“I am no longer”
One’s skin ceases to be a boundary between self and others

33. Mechanisms of Action
Double-edged sword Positive versus negative responses Hallucinogens act at a common CNS site to exert their psychedelic effects. This has not been proven

34. Types of hallucinogenic agents
DOM
MDA
MDMA
These agents vary in their hallucinogen or stimulant properties. MDA is more like amphetamines and MDMA is more like LSD

35. Third major group
The third major group of hallucinogens comprises the anticholinergic drugs, which block some of the receptors for the neurotransmitter in the brain

36. LSD Lysergic Acid Diethylamide Relatively a new drug
Ergotism- poisoning by toxic substances from the ergot fungus
Eating grains contaminated by the ergot fungus
Fungus produces compounds related to LSD, called the Ergot alkaloids

37. Albert Hofmann
1938, Albert Hofmann, a Swiss scientist worked on ergot compounds in a search for medical value He was trying to synthesize a drug to study psychosis

39. LSD LSD requires skills of a trained chemist
Synthesis and Administration, LSD is a complex molecule that requires about 1 week to be synthesized
LSD requires skills of a trained chemist

41. LSD
The most common form of LSD is paper blotter divided into about 1/4" squares called tabs. A single tab usually contains between ug of LSD. Paper blotters are created by taking a sheet of absorbant paper (usually decorated and perforated) and soaking it in a dilution of lysergic acid diethylamide. 

42. Adverse Psychedelic Effects
No typical pattern of response to LSD
Experience varies for each user
Psychotic adverse reaction (freakout)
Non-psychotic adverse reaction

43. Perceptual Effects Many kinds of unusual illusions can occur
Brain’s sensory processing is altered
Many kinds of unusual illusions can occur
Time distorted
An experience can be incredibly beautiful and uplifting, or unpleasant

44. Negative LSD-related Flashbacks
Body trip
Bad mind trip
Altered visual perception

45. Mescaline (peyote) Used for centuries Francisco Hernandez
Mescaline is one of approximately 30 psychoactive chemicals that have been isolated from the peyote cactus
Used for centuries
Francisco Hernandez
King Philip II of Spain
Mescaline is perhaps 1000 to 3000 times less potent than LSD and about 30 times less potent than other common hallucinogens such as psilocybin

46. Peyote

47. Mescaline’s Effects Increased body temp Anxiety Visual hallucinations
Dilation of the pupils “Mydriasis”
Increased body temp
Anxiety
Visual hallucinations
Alteration of body image
Users report losing all awareness of time

48. Mescaline’s Effects
Within 30 to 120 minutes after ingestion, mescaline reaches a maximum concentration in the brain. Effect may persist for 9 to 10 hours

49. Psilocybin
Psilocybin and psilocyn are the hallucinogenic principles contained in certain mushrooms. These “magic” mushrooms are generally grown in Mexico and Central America and have been used in native rituals for thousands of years

Can be eaten, or brewed

52. Psilocybin
1958, Albert Hofmann extracted psilocybin during his experiment with LSD. During his research he ate 32 mushrooms to feel the effects
Timothy Leary also carried out a series of experiments using psilocybin

53. DMT (Dimethyltryptamine)
Short acting hallucinogen found in the seeds of certain leguminous trees native to the West Indies and parts of South America
