|    Cocaine 
              Information From Narconon
 Cocaine is a potent and dangerous Central 
              Nervous System stimulant, processed from the South American Coca 
              Plant. Cocaine works by blocking the reabsorption of dopamine in 
              the brain ( a chemical messenger that assists in normal functioning 
              of the Central Nervous System and is associated with pleasure and 
              movement). Cocaine in it's powdered form is sniffed or mixed with 
              water and injected. More recently users are smoking a freebase form 
              of the substance termed Crack (so named for the "crackling" 
              sound produced when the mixture of cocaine and sodium bicarbonate 
              is heated).
             At one time cocaine had a somewhat exclusive 
              population of users. Today, with the advent of crack, it is cheaper 
              and more widely available. We have a dangerous and indiscriminate 
              scourge plaguing America and it's effects are reaching all across 
              the country, from the ivory towers of wall street to the dead-end 
              alleys of downtown metropolitan areas to the circle drives of suburbia. 
               Whether cocaine is used by injecting, snorting 
              or smoking the same risks are involved. Although, the onset of addiction 
              to cocaine may be much more rapid in the smoked form. Users will 
              experience dilated pupils, increased body temperature, constricted 
              blood vessels, increased heart rate and blood pressure. The euphoria 
              felt by users is due to hyperstimulation, reduced fatigue and mental 
              clarity.Other effects of cocaine abuse include restlessness, irritability, 
              and anxiety. In addition to user reported and scientifically backed 
              effects of the drug, sudden death can occur in rare occurences on 
              the first use.  The tolerance factor (how much 
              it takes to get "high") of cocaine makes the likelihood 
              of compulsive and addictive use very likely within the first few 
              uses, especially when used in the form of crack.  Prolonged abuse of cocaine may 
              cause an acute paranoia that will make users withdrawn, suspicious 
              and highly unpredictable. Alongside these tragic repurcussions is 
              the likelihood of death as a result of cardiac arrest or seizures 
              followed by respiratory failure.
