Drug use is generally defined as the use of a drug on a consistent basis which can 
            
 have physical or mental effects or can impair a person's social abilities. The substances 
            
 which I will discuss consist of hallucinogens, stimulants, and depressants. These 
            
 drugs affect moods, emotions, feelings and thinking processes and they can be mind-
            
 altering.  Leavitt (1995) says that a person dependant on drugs usually carries three basic 
            
 characteristics that are indicators. The  first characteristic is that the user continues to use 
            
 the drug for an extended period of time.  The second characteristic is that the user has 
            
 problems in stopping the use of the drug.  Leavitt (1995) says that these characteristics

 dropping out of school, trouble with the law, jail, losing a job, and family problems.  The 
            
 final characteristic of a drug dependent could be mental distress or physical pain due to

 chemicals make a person feel pleasure and take away pain either during sexual orgasm, 
            
 physical exercise or a spiritual experience.  Drug abuse is way of imitating these naturally 
            
 occurring chemicals in the brain.  Drug abusers find pleasure is quite easy to obtain 
            
 through drug usage.  The only problem with this is that when drugs are repeatedly used to 
            
 simulate endorphins, the body cuts down on the production of them.  This causes the drug
