Coca paste contains 40 to 91 percent cocaine. Addiction to coca paste develops in a few months and results in four distinct and successive phases of mental disorder: euphoria, dysphoria, hallucinosis, and paranoid psychosis. Because the craving created by coca-paste smoking is so strong, cure and rehabilitation are difficult. Treatment of the addiction includes detoxification, support therapy, self-control therapies and abstinence programs. Addicts have been known to relapse into coca-paste smoking after years of abstinence. Patients who have acceptable school or work adjustments and strong supportive families have the best prognosis for long-term drug-free lives. 58 references. (Author abstract modified)
