Information about Crack Cocaine

Crack Cocaine is a highly addictive form of cocaine that is popular for its intense high. It is a diluted form of the drug and a small amount of cocaine can be expanded into increasingly larger and weaker amounts of crack cocaine.

Chemistry

Crack cocaine, often nicknamed "crack", is believed to have been created and made popular during the 1980s. Because of the dangers for manufacturers of using ether to produce pure 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 (NH₄Cl), remains in the freebase cocaine after the mixture has evaporated. The “rock” that is thus formed also contains a small amount of water.

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 1:1 to 2:3 parts cocaine/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 adulterants 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 (NaHCO₃, common baking soda) is:

Crack cocaine usually contains 40% cocaine or less, depending on how much it has been bulked out with other substances. The other 60%-90% can be made up of anything, usually there is some level of acetone and bicarbonate, but it can be whatever the chemists/dealers have used to bulk the batch up with. Occasionally, highly toxic substances, such as rat poison, have been used, causing widespread health issues and deaths.

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. The high usually lasts around 15 minutes, after that time dopamine levels in the brain plummet, leaving the user feeling 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.

Dopamine is used in the formation of neural networks, or ways that we think. If someone does something correctly, the brain releases a small amount of the drug to reward and encourage similar behaviors. Crack use leads to the formation of new neural networks that are formed by large amounts of dopamine, which also contributes to the addictive nature of the drug. When users think about crack, the new neural pathways that crack has formed invoke positive emotions, as crack becomes more and more associated with intense euphoria.

Health issues

Constant crack use can lead to depression. When large amounts of dopamine are used up by crack, it is harder for the brain to generate motivation for other activities. It also releases a large amount of adrenaline into the body, which tends to increase heart rate and blood pressure, leading to cardiovascular problems. As mentioned earlier, any substance can be added to expand the volume of a batch, and occasionally highly toxic substances are used.

Getting the drug into the body presents a series of health risks. It cannot be snorted like regular cocaine, as is has been transmuted into an alkaline. Therefore, smoking is the most common method of ingesting the drug. Crack has a melting point of around 90 degrees C, 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 & blistered lips from having a very hot pipe pressed against the lips. Not surprisingly, this is often called crack lip.

Another significant health risk is the condition commonly known as crack lung. Hot smoke and ash often used in the smoking process do a large amount of damage, and inevitably people who use the drug intensely, or for more than a few months will display symptoms of dead tissue, weeping wounds, bleeding and burns.

Less commonly, the drug is injected. This is more damaging than smoking the drug, as it needs to be transmuted into an acid again in order to mix it up and inject it. This decreases the purity and increases the acidity levels and therefore damage to the veins. Another issue is frequency. Heavy heroin users would not often inject more than a few times a day. As the crack high lasts only 15 minutes, many users end up injecting the drug four times an hour, vastly accelerating the damage associated with intravenous drug use.

Crack baby

Crack baby is a pejorative term for a child born to a mother who used crack cocaine during her pregnancy.

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.^[1]

Claims regarding threats to fetal and infant health

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.
