It is considered as a powerful stimulant, appetite suppressant and anesthetic. In the Victorian era, many medicines contained cocaine, which were available for free use for babies and children especially when they were teething.

In the first twenty years of its making, Coca Cola consisted of cocaine but the laws regulated it in the early 1900’s and restricted its inclusion. Initially its usage has been considered as a rich mans drug, but the use of Crack Cocaine, which is a modified form of the original powdered form and it is prepared as a “Rock” or “Stone” and smoked in pipes, which made its usage down to street level.

Coca can also be eaten or brewed (boiled) as tea. Neither coca nor cocaine is physically addictive, but cocaine can develop a strong dependence. Cocaine as a stimulant increases the workload on the heart. When cocaine is taken nasally, nasal passages can be disturbed, which causes infections. Cocaine is also a local anesthetic, which can ‘numb’ the areas where it is applied.
