In the words of music legend Whitney Houston, “Crack is whack.” With all the attention this topic has been getting, it’s important to understand what crack cocaine actually is. Crack is a form of cocaine that comes from the leaves of the coca plant. When powdered cocaine is mixed with a weak base, like baking soda, it changes into solid “rocks.” These rocks have a lower melting point than powdered cocaine, which means they can be smoked instead of snorted. The name “crack” comes from the cracking sound it makes when heated.
Smoking crack allows it to enter the bloodstream quickly through the lungs, making it a fast and effective method. When the smoke enters the lungs, it rapidly passes through the membrane and reaches the brain in as little as 8 seconds. This is much faster than snorting cocaine, which takes about 10 minutes to reach the brain.
Once crack reaches the brain, it has effects similar to cocaine. Users initially feel energized, alert, and more aware of their surroundings. Crack stimulates a part of the brain called the Ventral Tegmental Area, which releases a large amount of dopamine. Dopamine is a chemical linked to pleasure and happiness. It travels between neurons and attaches to receptors that trigger positive feelings. Normally, dopamine would be reabsorbed back into the neuron, but crack blocks this process. This causes dopamine to build up and continuously stimulate the receptors, resulting in a pleasurable high that lasts about 10 minutes.
However, after this high, dopamine levels drop significantly, leading to feelings of depression and a strong urge to use more crack to feel good again. This cycle can lead to physical and psychological dependence, as well as increased irritability and restlessness. In some cases, crack use can cause Delusional Parasitosis, where users feel like bugs are crawling under their skin, leading to harmful behaviors.
On a more serious note, crack can have severe health consequences, including heart attacks, strokes, or even death. In summary, crack can have very serious effects on health and well-being.
