LSD LSD (Lysergic Acid Deithylamide)(Lysergic Acid Deithylamide)

Lysergic Acid Diethylamide (LSD) was discovered in 1938 by a Swiss scientist named Albert Hoffman.

Hoffman tested some on himself, not knowing the limits of a safe dosage

It was thought that the mind-altering properties of LSD could be used with medicinal purposes in the treatment of psychological disorders

LSD LSD (Lysergic Acid Deithylamide)(Lysergic Acid Deithylamide)

The discovery resulted from an investigation of partially synthetic amides of Lysergic acid.

LSD was synthesized with the intention of obtaining an analeptic

Methergine developed as a result of LSD research is used to stop hemorrhages.

PSILOCYBINPSILOCYBINCertain types of naturally

occurring mushrooms contain hallucinogenic chemicals known as psilocybin and psilocin.

Psilocybin and Psilocin are found in the liberty cap mushroom (Psilocybe semilanceata (Magic Mushroom)

Dried mushrooms contain about 0.4 % psilocybin and trace amounts of psilocin.

Page 20: Mind-Altering Drugs

PSILOCYBINPSILOCYBINPsilocybine and psilocine belong

to the tryptamine family and their effect is similar to the natural neurotransmitter serotonine, which is also known as the `happiness hormone'.

Psilocybine and psilocine are known as alkaloids which means they are nitrogenous substances that appear in nature. .

Effects of Psilocybin and Effects of Psilocybin and PsilocinPsilocin

Within 30 minutes of taking small amounts (about 1-2 grams) of mushroom, there is nausea, sweating, feeling hot and shaky, heart racing, lightheadedness, or anxiety.

A relaxed feeling and a sharpening of senses sometimes follow this. With larger amounts (2-14 grams) they may experience time distortion, euphoria, seeing brilliant colors, flashing lights and even shapes and images.

inability to distinguish from poisonous varieties

Poisoning occurs when there is excessive vomiting, diarrhea, headaches, chest pain, pounding and racing heart, fear, anxiety, paranoia, and seizures.

MARIJUANAMARIJUANA (cannabis) (cannabis)

Marijuana is a drug made from the stems, flowering tops, leaves and seeds of the hemp plant (cannabis sativa).

Page 26: Mind-Altering Drugs

MARIJUANAMARIJUANA (cannabis) (cannabis)

The active ingredient in Marijuana is a compound called Tetrahydrocannabinol (THC).

Structurally THC contains multiple carbon rings, with several methyl groups attached, and –OH group on a benzene ring, as well as a five carbon chain.

The concentration of THC is the determines the potency and effects of the drug.

Generally marijuana has a THC content of 1-3% with specialized breeding making contents of slightly higher possible.

Hashish, made from the resin of the hemp plant is much more potent with concentrations between 10 to 15%.

The THC content of any of the products of the hemp plant depends greatly on the environment in which the plant is grown.

1.Addictive properties are not entirely known.

2.Some experte believe that marijuana is less addictive than alcohol or nicotine, both of which are legal.

3.Risk of long term brain damage is not entirely known

Page 32: Mind-Altering Drugs

1. It is known that THC affects and influences the activity of cells at specific sites called cannabinoid receptors on nerve cells in the brain.

2.Some areas of the brain have many cannabinoid receptors; others have few or none.

3.Many cannabinoid receptors are found in the parts of the brain that influence pleasure, memory, thought, concentration, sensory and time perception, and coordinated movement.

Legalization of MarijuanaLegalization of Marijuana1. Increased costs to society:

especially from cancer and heart disease from smoking

2. Increased danger from people driving under the influence,

3.Marijuana abuse would increase4.Marijuana’s status as a gateway

drug would lead to increased addiction to more dangerous drugs such as cocaine, methamphetamines, and heroin
