body, change the way the body works or the way the person thinks or feels.
Illegal drug:
A drug that is not allowed by law because of its dangerous effects.
Narcotic:
A drug affecting the central nervous system so as to produce dizziness,
euphoria, loss of memory, lack of coordination, and eventually unconsciousness. Many
narcotics are derived from the opium poppy.
