Explore the science behind crack-cocaine, a form of cocaine derived from the coca plant and often referred to as 'rocks'. Learn why smoking this substance allows it to travel directly to the brain in as little as 8 seconds, resulting in intense, initial feelings of being energized, alert, and aware of senses. We explain the mechanism: crack acts on the Ventral Tegmental Area, blocking the dopamine transporter, which prevents dopamine from being reabsorbed and leads to euphoria. Understand the severe consequences, including extreme lows, dependence or addiction, depression, paranoia, and irritability. Serious risks include Delusional Parasitosis (the feeling of bugs under the skin), heart attacks, strokes, and potentially death.
