Why do crack dealer use cornstarch?

Crack dealers often use cornstarch as a cutting agent to increase the volume of their product while maintaining a similar appearance to pure crack cocaine. This practice allows them to maximize profits by selling less actual drug for the same price. Cornstarch is inexpensive, readily available, and relatively inert, making it a common choice among dealers looking to dilute their product without significantly altering its effects. However, this can pose serious health risks to users, as the impurities can lead to dangerous side effects.
