Cocaine Presentation Transcript

Slide 1 - Chemical Reactions in the Drug World Synthesis and Biological Actions of Cocaine
Slide 2 - Overview Cocaine Synthesis and Extraction Affects of Cocaine on the human body Cocaine in the media
Slide 3 - Cocaine Extraction Coca leaves are stripped from the plant and crushed, chopped, and/or pounded mixed with a solution of alcohol, gasoline, kerosene, or some other solvent that will remove the cocaine from the leaves.
Slide 4 - 2. Acid-Base Neutralization 1. Dissolve using solvents Extraction and Purification 3. Oxidation to ↑ purity colour Δ indicates end rxn
Slide 5 - Cocaine Purification The resulting liquid contains unpurified cocaine alkaloids and waxy material from the leaves. The waxy material is removed by heating and cooling the mixture, which solidifies the unwanted wax. cocaine alkaloids are isolated from the liquid using acid and base mixtures. The removed alkaloids are then treated with kerosene. The kerosene is removed and crystals of crude cocaine are left at the bottom of the tank. The crystals are dissolved in methyl alcohol.
Slide 6 - Cont’d Purification and Conversion 4. Removes precipitate from last rxn 5. acid-base neutralization 6. Dissolve in solvent 7. Dissolve in solvent crystallizes
Slide 7 - Cocaine Purification They are then recrystallized and dissolved in sulfuric acid, which results in cocaine that is about 60% pure. cocaine at this point is freebase cocaine (crack). When a person freebases cocaine, or makes crack, they are reversing what is done in the next process.

Slide 9 - Cocaine Conversion freebase is converted cocaine hydrochloride (a salt). The reasons for the conversion 1) left in this form for long it would lose its potency 2) To purify it to about 99% cocaine purity 3) To make it water soluble. Coke in this form can't be injected or snorted into the bloodstream. Any drug which is injected into the human body must be dissolvable in water, if it is not, it will remain in a non dissolved clump. Clumps cause strokes or heart attacks cocaine is further treated with oxidizing agents to become water-soluble . Further washing, oxidation and separation procedures with potassium permanganate, benzole, and sodium carbonate. The result is an odorless, white crystalline powder. With a bitter, numbing taste.
Slide 10 - Crack Cocaine Freebase/crack cocaine. Freebase/crack is derived from cocaine hydrochloride which has been chemically treated with ammonia (freebase) or baking-powder (crack) to free the potent base material from the salt. Free-base was originally produced by a dangerous four-or-five step process in which the hydrochloride salt was heated with water and a volatile liquid such as ether. Base cocaine in the form of 'crack' is safer to produce; Crack/free-base is indissoluble in water, so it can't easily be injected or sniffed.  it is smoked in pipes; burnt on tin foil; or mixed with tobacco and weed in a joint.

Slide 13 - Cocaine Methods of Use causes such pleasurable effects as reduced fatigue, increased mental clarity, and a rush of energy the more one takes cocaine, the less one feels its pleasurable effect which causes the addict to take higher and higher doses of cocaine in an attempt to recapture the intensity of that initial high
Slide 14 - Cocaine Methods of Use average high a user gets from snorting cocaine only lasts for 15-30 minutes smoking high, although more intense due to the rapidity in which the drug is absorbed into the bloodstream, lasts for an even shorter period of only about five to ten minutes crashing low, in which the addict craves more of the drug and in larger doses
Slide 15 - Cocaine’s effects on the nervous system one of the most potent, addictive recreational drugs Can cause irreversible damage to the nervous system
Slide 16 - Cocaine and the brain http://health.howstuffworks.com/crack6.htm
Slide 17 - Cocaine’s Effects on the Brain produces its pleasurable high by interfering with the brains pleasure centers where such chemicals as dopamine are produced drug traps an excess amount of dopamine in the brain, causing an elevated sense of well being
Slide 18 - This is your brain on drugs By inhibiting the brains release of dopamine and other neurochemicals, cocaine can cause serious and often irreversible damage to neurons within the brain cocaine users had a reduced number of dopamine neurons When flooded with the excess of dopamine created during a cocaine high, the brain reacts by making less dopamine, getting rid of this excess, and shutting down the dopamine neurotransmitters, sometimes permanently
Slide 19 - This is your brain on drugs the drug cause blood vessels to restrict, increases the body temperature, heart rate, and blood pressure, and cause the pupils to dilate increases ones breathing rate serious long-term effects to the central nervous system, including an increased chance of heart attack, stroke, and convulsions, combined with a higher likelihood of brain seizures, respiratory failures, and, ultimately, death
Slide 20 - Cocaine Overdose serious long-term effects to the central nervous system, including an increased chance of heart attack, stroke, and convulsions, combined with a higher likelihood of brain seizures, respiratory failures, and, ultimately, death overdose of cocaine raises blood pressure to unsafe heights resulting in permanent brain damage
