When you’re smoking crack, ideally you want to keep the flame on the crack and away from the Chore Boy: You want the rock to heat up and cook down into it. It starts to melt and then it slides. Given the physical evidence of a hypodermic and a cooking spoon, and as noted, they're tentatively associated with a person known to be you don't cook crack - you break it down with a citric acid such as lemon juice.
Crack or crack cocaine is a form of cocaine. It has not been neutralized by an acid to make cocaine hydrochloride, the pure form of the chemical. Crack comes in a rock crystal form that can be heated and inhaled or smoked. It is called 'crack' in reference to the cracking sound it makes when it is heated. Crack cocaine is a highly addictive stimulant.
Crack looks like irregularly-shaped off-white or white rocks.
Crack cocaine is almost always smoked or freebased. Freebasing involves heating the crack until it liquefies and inhaling the vapors through a pipe. The vapors are absorbed by the lungs, producing an immediate euphoric high.
Crack is a readily available form of cocaine. Cocaine is used because it produces euphoria, is a stimulant, suppresses appetite, and can be used as a pain reliever.
Users typically feel a 'rush' followed by a sense of alertness and well-being. Cocaine increases levels of the neurotransmitter dopamine, which is associated with pleasure and increased movement. The pleasant effects of crack wear off quickly (5-10 minutes), causing users to feel 'down' or depressed, more than before taking the drug. Some users report being unable to duplicate the intensity of the first exposure with subsequent use.
Crack is highly addictive, possibly even more than other forms of cocaine. Crack users are at risk for the usual effects of cocaine (dangerously elevated blood pressure, heart rate, and temperature, as well as the risk of seizure and cardiac arrest). They are also at increased risk of respiratory disorders, such as coughing, bleeding, shortness of breath, and lung trauma. Crack use can cause paranoia and aggressiveness.
Crack cocaine is made by dissolving powdered cocaine in a mixture of water and baking soda (sodium bicarbonate) or ammonia. This mixture is boiled, dried, and broken into rock-like chunks. The original cocaine comes from a paste made from the leaves of the South American coca plant.
