Can anyone really give a true definition of drugs?  We can state what we know and our opinions, but no one knows everything about them.  Drugs are very harmful and dangerous.  They cause many different cancers and diseases.  People most often smoke because of pressure from peers, themselves, parents, ads, and other reasons of their own.  People think smoking will make you look cool, take away bad feelings, relieve pain, and many other reasons.  Most drugs are depressants, not stimulants.  Depressants are any drug or chemical that decreases the activity of any bodily function.  Stimulants are any of a group of drugs that excite the central nervous system, increase alertness, and alleviate fatigue.  Most drugs are very addictive too.  After one or two cigarettes you may not be able to stop.  You may hide the truth from yourself if you smoke.  For example, saying that drugs don't hurt you and they help you relieve the pain when you know they really don't.  Some drugs like marijuana and cocaine are illegal.  If you are caught with the possession of illegal drugs you will go to jail.  The point is drugs are very harmful and you should not use them for those stupid reasons.  Is your life really worth risking for them?
