How are drugs classified? Drugs are commonly classified according to their legal status or their effects on the central nervous system. Legal and illegal drugs Laws and regulations control the availability, quality and price of the “legal” drugs. For example, tobacco may not be sold to persons under the age of 18. Illegal drugs Because they are illegal, there are no price or quality controls on the illicit drugs such as heroin and ecstasy.

The user also cannot be sure of a drug’s strength or purity. Various batches of an illegally manufactured drug may have different mixtures of the drug and additives such as poisons, caffeine or even talcum powder. Effects on the central nervous system There are three main types of drug affecting the central nervous system.

Hallucinogens Hallucinogens affect perception. People who have taken them may believe hey see or hear things that aren’t really there, or what they see may be distorted in some Way. The effects of hallucinogens vary a great deal, so it is impossible to predict how they will affect a particular person at a particular time.

This means that larger amounts are needed to obtain the desired effect. Other drugs used (poly drug use). Combining drugs can increase or alter the effects, often in unpredictable says.
