They might want to be similar to those who are already into drugs or they might want to be the user,s and react the same way how user's do..

Fraustaton is the major cause for drug abuse

Fraustation is the major reason leading towards drugs coz most of the youths easily get into drugs and when it comes to the time of fraustation and deppression most of the child start using drugs to reduce their problem.
Family fights,child abuse,rape etc are the major reasons for fraustation..Most of the family are not aware of their childrens nature,how they feel,what are they going through,what they are doing, so childrens feel carefree and take wrong direction for fun and finally leads to addicton.
Some of the families show over strictness towards their chidren and this cause fraustation because childrens feel they are tied up, they dont have freedom.
Such small things are also the reason for drug abuse.
Most of the tenager get into love stuffs and later when they break their reln then they fall into tragedy which also leads towards drug abuse..They start feelin everything fake,they find their sourrounding and environment different,they find everything unhappy and most of them feel like taking drugs to ignore his/her love...
