Both powder cocaine and crack cocaine come from the coca plant in South America. They’re both highly addictive and potent forms of cocaine that produce intense high and side effects, but these two substances are used differently and have distinctive appearances.[1]
If you suspect a loved one is using crack cocaine, it’s important to recognize not only the drug itself but any other signs of crack cocaine.
Key Points
- Crack cocaine is a potent, “smokable” form of cocaine derived from powder.
- Known as “rocks,” crack is distinctive in its color and appearance, though it can vary.
- People usually buy small doses of crack at one time, so it’s often easier to identify drug paraphernalia than the drug itself.
- The outward signs of crack use can be helpful in identifying crack abuse or addiction.
- Crack is highly addictive and has the same risks as powder cocaine with the additional risks of smoking.
What Is Crack Cocaine?
Crack cocaine is derived from the powder form of cocaine using a simple conversion process.[2] The powdered cocaine is dissolved in a mixture of water and ammonia or sodium bicarbonate (baking soda) and boiled until it’s solid. This solid is then removed, dried, and broken into pieces sold as cracks.
Named for the crackling sound it makes when heated, crack cocaine is smoked to produce an immediate high. It’s an impure form that’s easy and inexpensive to make, which led to its widespread use in the 1980s.
What Does Crack Look Like?
Crack cocaine crystals, known as “rocks,” can be anything from clear white to opaque white to off-white or yellowish in color.[3] Crack cocaine crystals vary in size and shape, as the solid form is broken into smaller pieces after conversion.
The color variations can be caused by the purity of the cocaine itself or adulterants like lidocaine, procaine, caffeine, or other drugs that have been added to mimic the effects or produce more potent effects.[4] Some additives are intended to add to the bulk of the product to create a larger profit margin for dealers.
Along with looking for paraphernalia, you can look at the person. Some people are better at hiding their paraphernalia, but they can’t hide some of the outward signs of crack use, which may include:[6]
- Excessive alertness and/or talkativeness
- Dilated pupils
- Restlessness
- Lip blisters
- Lip or finger burns
- Tremors or muscle twitches
- Blisters or sores on the skin from ‘coke bugs,’ or formication, which causes sensations of insects under the skin
- Volatile mood swings
- Low appetite
- Aggressive behavior
- Mania
- Paranoia
- Psychosis[7]
What Are the Risks of Using Crack?
Cocaine is a highly addictive drug, no matter its form. Using crack may lead to addiction more quickly, however, as smoking the substance delivers it into the bloodstream faster for a more intense, immediate high.[8] The high with crack is also short-lived, leading people to binge to chase that intensity, increasing their tolerance and addiction potential.
Crack carries the same general risks of cocaine use, which include constricted blood vessels, increased heart rate, temperature, and blood pressure, seizure, and cardiac arrest, as well as use-specific effects. Crack users may experience acute respiratory problems like coughing and shortness of breath, burns, and lung trauma (also known as crack lung).[9]
Crack Cocaine Addiction Treatment
Treatment for crack addiction is tailored to the needs of the individual, so it may include detox and treatment in an inpatient or outpatient facility. Many programs use behavioral therapies for cocaine addiction, including cognitive behavioral therapy (CBT) and contingency management, two leading therapies based on the idea that behaviors are learned and can be changed.[10] These therapies help people identify the influences and patterns that contribute to drug use and develop healthier behaviors.
Frequently Asked Questions
What Does a Crack Rock Look Like?
Crack rocks can vary in color and size, but they are generally small, irregular in shape, and range from white to tan in color. They’re usually around the size of cat food pellets.
What Color Is Crack?
Cracks vary in color depending on the impurities, but they are usually a shade of white, tan, or yellow with varying degrees of transparency.
What Does Crack Smell Like?
Crack is reported to have a distinctive chemical scent, like burning rubber or plastic, when it’s smoked. Though distinctive, the difference between a burning crack and a potentially volatile meth may not be obvious to the average person, so it’s important to report any odors to the proper authorities.
