Drug abuse means the taking in of harmful kind of things such as narcotics,hashish,Heroin and many more.
These drugs are very harmful for every age.Once you got addiction of any kind of drug it becomes so difficult to give it up.

Narcotics belong to Opiate family and are  commonly derived from the poppy plant.They are considered as highly addictive drug because they can change the chemistry and state of brain.Their usage can cause serious effects i.e hallucinations,loss of apetite,lethargy,difficulty in breathing,constipation and many more.
Hashish is made up of resins which we get from Cannabis plant.It induces drowsiness,euphoric and sedated effects.
Heroin is extracted from morphine(which is extracted from poppy plant).It is present in the form of white or brown powder or as a black sticky substance.Excessive usage of heroin can cause the clogging of blood vessels which in turn affect the vital organs i.e brain,lungs,liver,kidney.

Drug abuse is very common in developing as well non developing countries.Especially, youth is a huge victom of this abuse.They take a start with cigarette smoking and then this habit takes them towards many more addictions.
They inhale those things which make them physically unfit and mentally retarded as well such as they get mental illness (i.e Alzheimer disease is a common disorder),health deterioration,brain damage,aggressiveness etc.
Drug abusers can't involve themselves in any useful activity.They can't think properly and also their behaviour is so un predictable that people don't trust themselves and consider them patient.They cannot make any good decision in their social life.They cannot run their business so its a huge drawback for their family and country as well.
Besides doing drug addiction ,drug abuser also gets involved in many criminal activities such as burglary,robbery and even the murder for the sake of money to get their drug.
Its a first and foremost need to eliminate this abuse from our country because its an obstacle in the way of success.

Proper awareness campaigns should be held for drug abusers .Media can also paly his role in this regard.Family and parents should also keep an eye on thier children as it is said " A good man in an evil society seems the greatest villain of all."
