Crack cocaine is a highly addictive stimulant affecting the central nervous system. Users often exhibit significant weight loss, leading to a gaunt appearance. This change stems from physiological effects and behavioral patterns. These factors explain why crack cocaine use leads to physical deterioration.
Suppression of Hunger
Crack cocaine directly interferes with appetite regulation. As a stimulant, it impacts neurotransmitters like dopamine and norepinephrine, important for reward and satiety. Cocaine blocks dopamine reuptake, leading to excess dopamine, which contributes to euphoria, heightened energy, and reduced appetite.
This surge of dopamine and norepinephrine overrides natural hunger cues, making individuals feel less hungry or disinterested. It activates brain regions for satiety, further reducing the desire to eat. Consequently, users often skip meals or consume little, leading to a caloric deficit.
Accelerated Metabolism
Beyond appetite suppression, crack cocaine increases metabolic rate. The drug stimulates the central nervous system, leading to a surge in physiological activity. This includes elevated heart rate, increased blood pressure, and higher body temperature, a process known as thermogenesis.
These heightened bodily functions demand more energy, burning calories faster, even at rest. Cocaine’s stimulant properties also induce alertness and restlessness, leading to more physical activity or prolonged wakefulness. This constant physiological arousal and movement further contributes to energy expenditure, compounding the caloric deficit.
Neglect of Nutritional Needs
The lifestyle associated with crack cocaine addiction contributes to weight loss, separate from direct physiological effects. Users often prioritize obtaining and using the drug over fundamental needs like regular, nutritious meals. Food becomes secondary to the immediate gratification provided by the drug.
Financial resources are often diverted to acquire the drug, leaving little money for food. Erratic sleep patterns, constant activity, and general neglect of self-care, common with stimulant abuse, disrupt normal eating habits. These factors collectively lead to an energy deficit and poor nutritional intake, exacerbating the physical toll.
Body’s Response to Deprivation
The cumulative effect of suppressed hunger, accelerated metabolism, and chronic nutritional neglect forces the body into caloric and nutrient deficit. When the body lacks sufficient energy from food, it breaks down its own tissues to acquire fuel. Initially, glycogen reserves are depleted, followed by fat reserves.
As deprivation continues, the body breaks down muscle mass for energy, a process known as catabolism. Protein breakdown provides amino acids converted into glucose to sustain brain function. This catabolic state leads to emaciation, muscle wasting, and the “skinny” appearance often associated with prolonged crack cocaine use.
