I agree with Sky. Its so sad the drug abuse is a great reason for suicide.

Suicide is usually the result of a disorder called depression.

Somerimes failures in important causes in which full efforts has been used though results are nill.

Drug abuse is nit a reason of suicides, I think main reason is failure of teenage love,financial crisis,and lack of mutual understanding of love marriage etc
