Information regarding the side effects of drugs is very important. Read and document the most common drugs.

Drug addicts rarely sleep at night, but when they are exhausted and eat very little and irregularly.  People who use hallucinogenic drugs usually choose isolated spaces for consumption because the use of them causes hallucinations, causes them to shut themselves in, to perceive the world in a different way to make them unable to have normal conversations with other people.  They tend to shut themselves in, to stop communicating with others, to spend time with people who use drugs.

 Marijuana smokers often have the same medical problems with their airways as cigarette smokers.  Marijuana users are at risk for lung infection;  coughing, sneezing, being cold more often than people who do not use this drug.  The health risks are generally considered to be higher than those that occur in the case of smoking.
