This is known as kindling or inverse tolerance. With more use, one becomes more sensitive to toxic effects of cocaine while the ability to stimulate the pleasure centers of the brain decreases. Users need more and more cocaine to get the same rush. Using again in frequent intervals prevents users from experiencing the inevitable crash after the high. Cocaine is metabolized so quickly that the initial euphoria disappears very suddenly and is replaced by the crash.
Users experience intense cravings for the drug from neurochemical imbalances created by cocaine.
There I lay in the hospital almost dead from an overdose. My heart felt like it was about to jump out of my chest and yet all I could think about was getting another hit. Withdrawal, Cravings, and Relapse Similar to symptoms of the crash, withdrawal symp- toms from cocaine include inability to feel pleasure, lack of motivation and energy, temporary elation, and intense cravings for the drug. You know, there's no specific time that I can remember where before I went into relapse that I actually decided to go and use again. That s the cunningness of this thing.
