3. Price of euphoria… • Tolerance – occurs when, over time, an ever-increasing dose of a drug is required to achieve the same effect • Physical dependency • Results when the body becomes accustomed to the regular intake of a drug • Can happen if the drug user takes a new dose before the effects of the previous dose have worn off • Withdrawal sickness (cramps, nausea, chills, vomiting, insomnia, convulsions, pain, and hallucinations)

4. Price of Euphoria…. • Psychological dependency • deep need for the continued intake of a drug occurs in an individual

5. Ex. Famous experiment by NY City Department of Health: Rat, two levers, cocaine, food

6. When substances, legal or illegal are take strictly for pleasure they are considered “drugs of abuse” or “illicit drugs” • In the U.S. 75 % of the evidence being examined in forensic labs are drug related.

7. Classes of drugs: Narcotics: • analgesics relieve pain by depressing central nervous system activity. Reduces body functions such as blood pressure, pulse rate, and breathing rate • Mild analgesics are OTC drugs= aspirin, Tylenol and Motrin • Illicit narcotics come from opium • opium derivatives: codeine, morphine, heroin • Abuse or overuse leads to physical dependence • Methadone is used in the U.S. as a heroin substitute

8.

17. Marijuana Facts • Greenish-brown mixture of the leaves, flowers, stems, and seeds of the plant Cannabis • Grows in most parts of the world • Active ingredient is tetrahydrocannabinol (THC) • Bind to specific receptor sites in the human brain which trigger the euphoric effect for which the drug is taken

35. History of Heroine • 3400 B.C. cultivated by the Sumerians who called it Hul Gil which means “joy plant” • Arabs and Turks introduced it to the Chinese • A mixture of opium, alcohol, and herbs was sold to the public as laudanum • In 1898 Bayer marketed a new wonder drug, Bayer Heroin

37. History of Cocaine • Leaves of the coca plant, Erythroxylon coca, were given to Inca royalty in keeping with their religious and cultural beliefs • The South American Indians chewed on the leaves to get additional strength and endurance • In the 1880’s Sigmund Freud considered cocaine a miracle drug that led to clarity of mind • In 1886 the Coca Cola Co. marketed its new soft drink, made from the same coca leaves, as an alternative to alcoholic drinks • One bottle of Coca Cola contained about 60 mg of cocaine • In 1903 the company was forced to remove cocaine from its beverage, but it still uses the leaves for flavor

38. Cocaine • Stimulant that acts on the central nervous system to make the user feel better or increase energy • Stimulants increase the amount of norepinephrine and dopamine in the brain, which increases blood pressure and heart rate, constricts blood vessels, increases blood glucose, and increases breathing. • Effects • increase alertness • Attention • energy along with a sense of euphoria. • potential for cardiovascular failure (heart attack) or lethal seizures.

39. Methods of extracting cocaine • Leaves are mashed and soaked • It is produced by combining coca paste and hydrochloric acid. • Powder cocaine is a white powdery substance that is abused by snorting, or by dissolving in water and injecting into a vein. This form of cocaine cannot be smoked. Powder cocaine is much more expensive than crack cocaine. • The slowest onset of cocaine’s effects occurs when it is snorted, and this can take up to 20 minutes. The effects last up to 60 minutes. When injected, cocaine reaches the brain within one minute and the effects last for up to 30 minutes.

40. Crack Cocaine • According to the US Dept. of Justice, crack cocaine is more psychologically addicting than powder cocaine, and is thus more likely to result in chronic and heavy use. • Produced from powder cocaine and is smoked. • Crack is essentially powder cocaine mixed with water and baking soda which is dried into a solid mass. • This mass is ‘cracked’ into rocks that are smoked. • takes about 20 seconds to reach the brain, and its effects last for about 30 minutes.

41. Cocaine Addiction • Cocaine interacts with dopamine, norepinepherine, and serotonin. • It blocks the reuptake of these chemicals in the brain by binding to the transporters that usually remove the excess of the neurotransmitters from the synaptic gap. • Prevents them from being reabsorbed, and instead their concentration is higher than usual in the synapses. • Dopamine is implicated in the production and development of dependency, serotonin produces feelings of confidence, and norepinephrine interacts with energy levels.

42. MDMA a.k.a. Ecstasy • A hallucinogen that is a member of synthetic drugs used at nightclubs and referred to as club drugs • Produced by Merck Pharmaceutical • In 1976 Alexander Shulgin of San Francisco taste-tested it • “I feel absolutely clean inside, and there is nothing but pure euphoria.”
