Street drugs are psychoactive drugs that have no approved medical usage, and therefore, are not available by prescription for any purpose. Despite this fact, they are readily available in modern society. Most drugs are known by a number of different Street Names. Street drugs include uppers, downers, synthetics, and hallucinogens, and all are designed to alter the mood. While marijuana is still considered a street drug by federal law, it's status is in rapid transition. Other street drugs are universally considered illegal, dangerous for the user's health, and a threat to the health of those around him or her. All street drugs can be used in different ways and can affect any one individual different from another.
