Generally taken by inhalation and oral ingestion, these are known for their effects on cardiovascular system of the body. Cocaine Coca alkaloid or cocaine is obtained from coca plant Erythroxylum coca . It has a potent stimulating action on central nervous system, producing a sense of euphoria and increased energy.
