Crack cocaine 49714 226162599 2008-07-17T02:47:44Z 70.23.226.229 /* Psychological effects */ {{Refimprove|date=February 2008}} [[Image:crack street dosage.jpg|thumb|right|A pile of crack cocaine ‘rocks’.]] '''Crack cocaine''' is a solid, smokable form of [[cocaine]]. It is a [[freebase (chemistry)|freebase]] form of cocaine that is made using baking soda ([[sodium bicarbonate]]) in a process to convert cocaine hydrochloride (powder cocaine) into [[methylbenzoylecgonine]] (freebase cocaine). == Chemistry == Crack [[cocaine]], often nicknamed "''crack''" after the sound made during its manufacture, was created and made popular during the 1980s{{Fact|date=May 2008}}. Because of the dangers for manufacturers of using [[ether]] to produce pure [[Cocaine#Freebase|freebase]] cocaine, producers began to omit the step of removing the freebase [[precipitate]] from the [[ammonia]] mixture. Typically, filtration processes are also omitted. The end result is that the cut, in addition to the ammonium salt (NH<sub><small>4</small></sub>Cl), remains in the freebase cocaine after the mixture has evaporated. The “rock” that is thus formed also contains a small amount of water. [[Image:crackspoon.jpg|thumb|right|A spoon with a mixture of [[baking soda]], cocaine and a small amount of water, when heated from below, small crack cocaine ‘rocks’ will begin to form in the mixture.]] [[Sodium bicarbonate|Baking soda]] is now most often used as a base rather than ammonia for reasons of lowered odor and toxicity; however, any [[weak base]] can be used to make crack cocaine. When commonly "cooked" the ratio is 3:4 parts cocaine per [[bicarbonate]]. This acts as a filler which extends the overall profitability of illicit sales. Crack cocaine may be reprocessed in small quantities with water (users refer to the resultant product as "cookback"). This removes the residual bicarbonate, and any [[adulterant]]s or cuts that have been used in the previous handling of the cocaine and leaves a relatively pure, anhydrous cocaine base. The net reaction when using sodium bicarbonate (NaHCO<sub><small>3</small></sub>, common baking soda) is: <div align="center" style="line-height: 2em;">Coc-H<sup><small>+</small></sup>Cl<sup><small>–</small></sup> + NaHCO<sub><small>3</small></sub> → Coc + H<sub><small>2</small></sub>O + CO<sub><small>2</small></sub> + NaCl</div> Crack cocaine when processed correctly, may contain almost 75% of the original cocaine alkaloid as it did before being what is called on the streets as buffed{{Fact|date=May 2008}}. Buffing cocaine is the process of adding different substances usually chemicals closely related to the original alkaloid in attempts of increasing the yield of the product. Most forms of additives can be easily boiled off in while cooking, i.e baking soda (sodium bicarbonate), Inositol (vitamin b8) and even forms of baby laxatives (that have been used to add additional weight to the cocaine). Crack cocaine is usually purchased in rock form already, although it is not uncommon for some users to rather "wash up" or "cook" the cocaine into crack themselves. This process is done with baking soda (sodium bicarbonate), water, and a spoon. Once mixed and heated the bicarbonate breaks down into carbon dioxide and sodium carbonate, which then reacts with the hydrochloride from the cocaine molecule, leaving cocaine as an oily free base. Once separated from the hydrochloride the cocaine alkaloid floats to the top of the now leftover liquid. It is at this point that the oil is picked rapidly, usually with a pin or long thin object. This pulls the oil up and spins it, allowing air to set and dry the oil, and allows the user and/or maker to roll the oil into the rock-like shape. Unlike cocaine hydrochloride, "crack cocaine" when smoked allows for a quicker absorption into the blood stream, coupled with the fact that "crack" is considered more potent than cocaine hydrochloride, users obtain an intense high a lot quicker than the normal method of inhaling it. Health risks appear to be almost the same in either method, smoking or inhalation although, studies have shown that long-term snorting of cocaine in powder form can, after extensive use, destroy tissues in the nasal cavity, and has been known to create [[deviated septum|deviated septa]]. == Psychological effects == Cocaine is a substance that affects the brain chemistry of the user. Its main effect is to release a large amount of [[dopamine]], a brain chemical inducing feelings of [[euphoria (emotion)|euphoria]]. In addition, smoking freebase cocaine releases [[methylecgonidine]] into one's body, something which insufflating or injecting powder cocaine does not do. Methylecgonidine is a methylated form of cocaine in much the same way that [[methamphetamine]] is a methylated form of [[amphetamine]]. The high usually lasts around 15 minutes, after which time dopamine levels in the brain plummet, leaving the user feeling [[depression (mood)|depressed]] and low. A typical response among users is to have another hit of the drug; however, the levels of dopamine in the brain take a long time to replenish themselves, and each hit taken in rapid succession leads to increasingly less intense highs. It is the intense desire to recapture the initial high that is so addictive for many users. When injected into the bloodstream, the substance releases a much stronger effect of [[euphoria (emotion)|euphoria]]. == Health issues == When large amounts of dopamine are released by crack consumption, it becomes easier for the brain to generate motivation for other activities. The activity also releases a large amount of adrenaline into the body, which tends to increase heart rate and blood pressure, leading to long-term cardiovascular problems. It is suggested by research that smoking crack or freebase cocaine has additional health issues beyond other methods of taking cocaine. Many of these issues relate specifically to the release of methylecgonidine, and the specific effect of methylecgonidine on the heart,<ref>{{cite journal |author=Scheidweiler KB, Plessinger MA, Shojaie J, Wood RW, Kwong TC |title=Pharmacokinetics and pharmacodynamics of methylecgonidine, a crack cocaine pyrolyzate |journal=[[J.

Occasionally, highly toxic substances are used, with an indefinite range of corresponding short- and long-term health risks. The task of introducing the drug into the body further presents a series of health risks. Crack can not be snorted like regular cocaine, so smoking is the most common consumption method. Crack has a melting point of around {{nowrap|90 °C}} {{nowrap|(194 °F)}}, and the smoke does not remain potent for long. Therefore, crack pipes are generally very short, to minimise the time between evaporating and losing strength. This often causes cracked and blistered lips, colloquially "crack lip", from having a very hot pipe pressed against the lips. The use of "convenience store crack pipes" - glass tubes which originally contained small artificial roses - may also create this condition. These pipes are not durable and will quickly develop breaks; users will typically continue to use the pipe until it is only about 1/3 of its original length.{{Fact|date=March 2008}} == Legal status == Crack cocaine is listed as a [[Single Convention on Narcotic Drugs#Schedules of drugs|Schedule I]] drug in the United Nations 1961 [[Single Convention on Narcotic Drugs]], making it illegal for non-state-sanctioned production, manufacture, export, import, distribution, trade, use and possession.<ref name="emcdda">{{cite web | title = Cocaine and Crack | publisher =European Monitoring Centre for Drugs and Drug Addiction | url =http://www.emcdda.europa.eu/?nnodeid=25482#control | accessdate = 2008-05-01 }}</ref><ref name="incb">{{cite web | title = Single Convention on Narcotic Drugs, 1961 | publisher =International Narcotics Control Board | url =http://www.incb.org/pdf/e/conv/convention_1961_en.pdf | accessdate = 2008-05-01 }}</ref> In the [[United States]] cocaine is a [[Controlled Substances Act#Schedule II drugs|Schedule II]] drug under the [[Controlled Substances Act]] since it has high abuse potential but also carries a medicinal purpose.<ref>{{uscsub|21|812|b|2}} {{retrieved | accessdate=2008-05-01}}</ref> Under the DEA listing of schedule I substances, crack is not considered separate from cocaine since they are essentially the same drug compound in different forms.

There has been some controversy over the disproportionate sentences [[mandatory sentencing|mandated]] by the [[United States Sentencing Guidelines]] for crack cocaine since 1987. Whereas it is a 5-year minimum sentence for trafficking 500g of powdered cocaine, the same sentence can be imposed for mere possession of 5 grams of crack cocaine, a 100:1 ratio. There is no mandatory minimum sentence for mere possession of powder cocaine.<ref>Sabet, Kevin A.

There remains some dispute as to whether cocaine use during [[pregnancy]] poses a genuine threat to the [[fetus]]. The official opinion of the [[National Institute on Drug Abuse]] of the United States warns about health risks while cautioning against stereotyping: :Many recall that “crack babies,” or babies born to mothers who used crack cocaine while pregnant, were at one time written off by many as a lost generation. They were predicted to suffer from severe, irreversible damage, including reduced intelligence and social skills. It was later found that this was a gross exaggeration. However, the fact that most of these children appear normal should not be overinterpreted as indicating that there is no cause for concern. Using sophisticated technologies, scientists are now finding that exposure to cocaine during fetal development may lead to subtle, yet significant, later deficits in some children, including deficits in some aspects of cognitive performance, information-processing, and attention to tasks—abilities that are important for success in school.<ref>[http://www.drugabuse.gov/ResearchReports/Cocaine/cocaine4.html#maternal NIDA - Research Report Series - Cocaine Abuse and Addiction<!-- Bot generated title -->]</ref> They also warn about the threat of [[breastfeeding]]: "It is likely that cocaine will reach the baby through breast milk." The [[March of Dimes]] advises the following regarding cocaine use during pregnancy: :"Cocaine use during pregnancy can affect a pregnant woman and her unborn baby in many ways. During the early months of pregnancy, it may increase the risk of miscarriage. Later in pregnancy, it can trigger preterm labor (labor that occurs before 37 weeks of pregnancy) or cause the baby to grow poorly. As a result, cocaine-exposed babies are more likely than unexposed babies to be born with low birthweight (less than 5½ pounds). Low-birthweight babies are 20 times more likely to die in their first month of life than normal-weight babies, and face an increased risk of lifelong disabilities such as mental retardation and cerebral palsy. Cocaine-exposed babies also tend to have smaller heads, which generally reflect smaller brains. Some studies suggest that cocaine-exposed babies are at increased risk of birth defects, including urinary-tract defects and, possibly, heart defects. Cocaine also may cause an unborn baby to have a stroke, irreversible brain damage, or a heart attack. == See also == *[[War on Drugs]] *[[Drug abuse]] *[[Crack epidemic]] *[[CIA and Contras cocaine trafficking in the US]] == References == <references/> http://www.usdoj.gov/dea/concern/cocaine.html == External links == *[http://www.frankreport.com/Author/Articles/29June00.html Frank Parlato's interview] with two 19-year old crack dealers * [http://drugaddictionzone.com/questions-and-answers/why-is-crack-so-hard-to-stop-using (US)Why is crack cocaine so hard to stop using?] * [http://www.motherjones.com/news/feature/1995/07/greider.html Crackpot Ideas] - July/August 1995 issue of ''[[Mother Jones (magazine)|Mother Jones]]''. * [http://advocatesforpregnantwomen.org/articles/crackbabyltr.htm Top Medical Doctors and Scientists Urge Major Media Outlets to Stop Perpetuating "Crack Baby" Myth] - a [[petition]]. * [http://www.mapinc.org/drugnews/v98/n809/a07.html US:The Myth of the 'Crack Baby'] * [http://news.bbc.co.uk/1/hi/programmes/file_on_4/7053214.stm The rising peril of crack cocaine (UK)] * [http://jpet.aspetjournals.org/cgi/content/full/307/3/1179#FIG6 Effects of methylecgonidine on heart rate] {{Wiktionary}} {{stimulants}} [[Category:Benzoates]] [[Category:Carboxylate esters]] [[Category:Class A drugs]] [[Category:Cocaine]] [[Category:Cocaine sentencing]] [[Category:Drug control history]] [[Category:Dopamine reuptake inhibitors]] [[Category:Local anesthetics]] [[Category:Quechua loanwords]] [[Category:Stimulants]] [[Category:Sympathomimetic amines]] [[Category:Drug addiction]] [[cs:Crack (droga)]] [[de:Crack (Droge)]] [[et:Crack]] [[es:Crack (droga)]] [[eu:Crack (droga)]] [[fr:Crack (stupéfiant)]] [[gl:Crack (droga)]] [[hr:Crack]] [[is:Krakk]] [[it:Crack (stupefacente)]] [[lt:Krekas]] [[nl:Crack]] [[pt:Crack]] [[simple:Crack (drug)]] [[sl:Crack]] [[fi:Crack]] [[sv:Crack (narkotika)]]
