Drug Abuse is the excessive use of drugs to produce pleasure or to escape reality despite its destructive effects.
*Narcotics - drugs used to relieve pain, e.g. morphine, heroin, codeine, opium, cocaine etc. *Stimulants - used to keep one alert - amphetamine capsules and tablets. *Depressants - depresses the central nervous system and relieves anxiety - caffeine, valium.

More dangerously, the short term effects of the drug - whether they involve euphoria, extra energy, sensory enhancement or heightened performance-tend to become so alluring that the drug takes over the user's life. The line is crossed from drug abuse to drug addiction when using drugs stops being a choice and becomes a necessity - it controls the user and not the other way round - you are convinced that the drug is necessary for you to have a feeling of well being or even to get through the day.

Nothing becomes more important to you than getting high on your choice of drugs - not your studies or other academic activities, your job, kids, spouse etc. Getting high becomes so important that you are willing to sacrifice your education, work, family, home and any other important or necessary thing even as one denies that he has a problem. At the same time, the drug is not only something you want but your brain and body come to need. In fact, your brain and body get used to the amount of the substance you have been using
