How Crack Cocaine Works In the 1980s, a new drug emerged. Because of its cheap cost and quick and intense high, crack cocaine quickly gained popularity among users, especially in poor urban areas. Within two decades, the crack had exacted a heavy toll, leaving serious physical and emotional side effects not only on its users, but on entire communities and on the United States as a whole.

In this article, we'll explain how crack is made, what effects it has on the body and how law enforcement and health officials are working to stem its spread.
What is Cocaine? Crack is made from cocaine -- a powdered drug that is derived from the leaves of the coca plant, which grows primarily in South America. Although cocaine didn't gain notoriety in the United States until the 1980s, it has been in use for centuries. Many generations of South American Indians have chewed its leaves to give them strength and energy.

Coca plant
Cocaine was first isolated from coca leaves in the mid-1800s. Back then, it was used for medicinal purposes in drinks -- and yes, the legend is true: Coca-Cola did once contain cocaine. By the late 1800s, cocaine was also being used as an anesthetic and to prevent excess bleeding during surgery. By the following century, people began to realize that cocaine was an addictive narcotic, and non-medical use of the drug was made illegal with the passage of the Harrison Narcotics Tax Act in 1914.

Powder cocaine
The chemical formula of cocaine is C17H21NO4. See Wikipedia: Cocaine for a look at its chemical structure. Cocaine as a drug is taken in one of three ways: It is snorted, injected or smoked. The snorted form, cocaine powder, is made by dissolving coca paste from the coca leaves in a mixture of hydrochloric acid and water. Potassium salt is added to the mixture to separate out undesired substances to be removed. Ammonia is then added to the remaining solution, and the solid powder cocaine separates out. To inject cocaine, the user mixes the powder with a small amount of water and uses a hypodermic needle to force the solution directly into a vein.
The Cocaine Trade Most of the cocaine that comes into the United States today originates in Colombia, Bolivia and Peru. Cocaine is usually smuggled into the United States across the Mexican border. It arrives in the country in powder form and is converted to crack by the wholesaler or retailer (gangs make up most of the retail market in the United States).
Cocaine powder forms the base of freebase cocaine. Freebase cocaine has a low melting point, so it can be smoked. It is made by dissolving powder cocaine in water and a strong alkaloid solution such as ammonia. Then, a highly flammable solvent like ether is added, and a solid cocaine base separates out from the solution. Crack cocaine is an easier-to-manufacture form of freebase cocaine.
Manufacturing Crack Cocaine
Why "Crack"? Crack cocaine is also made from powder cocaine, but The word "crack" comes from the because its production doesn't require the use of cracking sound the rock crystal flammable solvents, it is safer to make than freebase makes when it is heated in a cocaine. To make crack, powder cocaine is dissolved in a crack pipe. The sound is caused mixture of water and either ammonia or sodium by the sodium bicarbonate. bicarbonate (baking soda). The mixture is boiled to separate out the solid, and then it's cooled. The solid is then dried and cut up into small nuggets, or "rocks."

Crack cocaine (in the filter on the right)
Crack rocks are white or tan in color and typically range in size from .1 to .5 grams. According to the U.S. Drug Enforcement Agency (DEA), crack rocks contain between 75 percent and 90 percent pure cocaine.
Crack in the Body Most users smoke crack, although in rare cases, they may inject it. To smoke crack cocaine, the user places the drug into a small glass pipe (sometimes called a "straight shooter"). He or she then places a small piece of a steel wool at one end of the pipe tube and puts the rock on the other side of this filter. When the rock is heated from below, it produces a vapor, or smoke. The user inhales that vapor into his or her lungs. From there, Photo courtesy U.S. DEA the drug is taken up by the person's bloodstream. Crack cocaine is usually smoked. When it gets into the body, crack acts upon a part of the brain called the ventral tegmental area (VTA).
It interferes with a chemical messenger in the brain called dopamine, which is involved in the body's pleasure response. Dopamine is released by cells of the nervous system during pleasurable activities such as eating or having sex. Once released, dopamine travels across a gap between nerve cells, called a synapse, and binds to a receptor on a neighboring nerve cell (also called a neuron). This sends a signal to that nerve cell, which produces a good feeling. Under normal conditions, once the dopamine sends that signal it is reabsorbed by the neuron that released it. This reabsorption happens with the help of a protein called the dopamine transporter. Crack interrupts this cycle. It attaches to the dopamine transporter, preventing the normal reabsorption process. As dopamine builds up in the synapse, it continues to stimulate the receptor, creating a lingering feeling of exhilaration or euphoria in the user.
Because crack is inhaled as a smoke, it reaches the brain much faster than inhaled powder cocaine. It can get to the brain and create a high within 10 to 15 seconds, compared to the 10 to 15 minutes it takes to feel the effects of snorted cocaine. The crack cocaine high can last anywhere from five to 15 minutes.
Side Effects of Crack Use While crack is creating a feeling of exhilaration in the user, it is also leaving a number of significant and potentially dangerous effects on the body. People who take it even a few times are at increased risk for heart attack, stroke, respiratory problems and severe mental disorders.

As crack moves through the bloodstream, it first leaves the user feeling energized, more alert and more sensitive to sight, sound and touch. Heart rate increases, pupils dilate and blood pressure and temperature rise. The user may then start to feel restless, anxious and/or irritable. In large amounts, crack can make a person extremely aggressive, paranoid and/or delusional. Because of its effects on the heart rate and breathing, crack can cause a heart attack, respiratory failure, strokes or seizures. It can also affect the digestive tract, causing nausea, abdominal pain and loss of appetite. If crack is taken with alcohol, the two substances can combine in the liver to produce a chemical called cocaethylene. This is a toxic and potentially fatal substance that produces a more intense high than crack alone but also raises heart rate and blood pressure more than crack alone, leading to its potentially deadly results.
Crack Babies - Myth or Reality? In the mid-1980s, when crack was a burgeoning public health issue, a related problem emerged: the phenomenon of the so-called "crack baby." In 1985, Dr. Ira Chasnoff wrote an article in the New England Journal of Medicine claiming that babies who were exposed to crack in the womb wound up with permanent cognitive impairment. Soon, images of "crack babies" were everywhere in the media. They became symbolic of the war against drugs. Since then, many researchers have challenged the idea of the crack baby. A 2004 study by the Society for Research in Child Development found that prenatal cocaine exposure did not affect a child's development by age two, and it suggested that the harmful effects previously found in cocaineexposed babies may actually have had more to do with post-natal care than with exposure to the drug in the womb. But despite the recent findings, doctors agree that crack is absolutely unsafe to take during pregnancy. Babies who are exposed to crack in the uterus are often born prematurely and tend to be smaller than other babies. Crack exposure can also contribute to developmental and cognitive delays.
How Do People Get Addicted to Crack?

Researchers have found that cocaine-addicted monkeys will press a bar more than 12,000 times to get a single dose of it. As soon as they get it, they will start pressing the bar for more. Crack and other addictive drugs chemically alter a part of the brain called the reward system. As mentioned previously, when people smoke crack, the drug traps the chemical dopamine in the spaces between nerve cells. Dopamine creates the feelings of pleasure we get from enjoyable activities such as eating and having sex. But in crack users, dopamine keeps stimulating those cells, creating a "high" -- a euphoric feeling that lasts anywhere from five to 15 minutes. But then the drug begins to wear off, leaving the person feeling let-down and depressed, resulting in a desire to smoke more crack in order to feel good again. The brain responds to the dopamine overload of the crack high by either destroying some of it, making less of it or shutting down its receptors. The result is that, after taking the drug for a while, crack users become less sensitive to it and find that they must take more and more of it to achieve the desired effect. Eventually, they cannot stop taking the drug because their brains have been "rewired" -- they actually need it in order to function. How long does it take to become addicted? That varies from person to person, and an exact number is difficult to pin down, especially when physical addiction is paired with psychological addition. Of course, not everyone reacts the same way to extended use. Some users actually become more sensitive to crack as they take it. Some people die after taking a very small amount because of this increased sensitization.
