U.S. Navy Dr. Walt Miner gives historical background of LSD (Lysergic acid diethylamide) drug in the United States.
The film gives an introduction and briefs the history of illegal drug LSD (Lysergic acid diethylamide). U.S. Navy Doctor Walt Miner speaks about revealing the facts about LSD which can be documented. He speaks about the historical background of LSD. He says that LSD is synthesized from lysergic acid derived from ergot, a grain fungus that typically grows on rye. He says that ergot is a fungus that grows on grains and other cereals. He speaks about Swiss chemists Albert Hofmann and Stahl who tried to make modifications in LSD molecule in 1938. He mentions the event of 1943 when Dr. Hofmann intentionally ingested 250 micrograms of LSD in his laboratory and how he felt uncomfortable. Dr. Walt Miner further explains how unique and powerful LSD drug is and says that the most unique thing about LSD is effective dose of the material. Miner states that effective dose for LSD can range from 0.5 micrcograms to 1.5 micrograms per kilogram of body weight.To explain the effective dosage of LSD, he displays a piece of wax paper where a mark is made with a pen. A penny is placed beside that mark to compare the two sizes. Dr. Miner informs that the ink mark weighs some micrograms. Dr. Miner takes one drop of human blood from a tube and says that this one drop contains 330 million cells and in comparison to that the weight of LSD to produce its effect is equal to the weight of two blood cells.
U.S. Navy Dr. Walt Miner explains the effectiveness and uniqueness of LSD (Lysergic acid diethylamide) drug in the United States.
LSD (Lysergic acid diethylamide) drug research in the United States. U.S. Navy Doctor Walt Miner tries to explain how illegal drug LSD is very unique and powerful. He says that LSD is effective on any animal during a research. Another unique thing is that it does not matter how LSD is taken by a person as it does not have any specific route of administration. Further he says that the latent time for LSD remains the same in all the different ways of intake. Dr. Miner explains how LSD acts on a human body and says that this drug does not produce effect but acts as a catalyst and allows the otherwise possible chemical reactions in the human brain. He also discusses about the taste of LSD drug.
U.S. Navy Dr. Walt Miner summarizes mental effects of LSD (Lysergic acid diethylamide) drug in the United States.
The effects of LSD (Lysergic acid diethylamide) drug on the human body. U.S. Navy Doctor Walt Miner explains the effects of LSD drugs on human body in terms of mental and physical effects. He states that mental effects are more important than the physical effects. Dr Miner says that the mental effects of illegal drug LSD depend on 'Set and Setting' which describes the context for LSD drug experiences: one's mindset and the setting in which the user has the experience. Dr Miner summarizes physical effects like feeling anxious and heart beating faster. He summarizes mental effects like loss of contact with reality, loss of body image and loss of body sense of time. He calls it a period of insanity for an LSD user. He further explains on a blackboard how and when the mental effects happen in a human body. He graphs effects and time on the blackboard. He explains the onset, peak and depression of mental effects of LSD in a total trip of 72 hours. Further he compares LSD with alcohol.
