A drug is any chemical or biological substance, synthetic or non-synthetic, that when it is taken into the organism's body, it will in some way alter the functions of that organism.
The excessive consumption of those substances can produce dependency, stimulation or depression of the central nervious system.
Drug addiction is a condition characterized by compulsive drug intake, craving and seeking, despite what the majority of society may perceive as the negative consequences associated with drug use.
Such persons are dependent on the drug, but are not addicted. One is addicted, rather than merely dependent, if one exhibits compulsive behavior towards the drug and has difficulty in quitting it.
There are drugs that are no legal like cocaine.
