Who is the Deceiver?

Mohit sat silent, on the backseat of his father’s Chevrolet unaware of the wedding procession, with its bright light and colorful people that were passing by. The noise of music and laughter failed to penetrate into the confused and disoriented mind of Mohit.
Mohit was just returning from the Doctor after a thorough check up of his body.
He was just about to celebrate his 20th birthday on the coming Sunday but instead of joy and anticipation he was remorseful and shocked. He still could not believe what the Doctor has just told him. Mohit was suffering from some liver problem. The doctor said it was serious enough but not life threatening as such. Mohit has to really undergo through medical treatment now. He has to be very careful with his habits and lifestyle.
Mohit’s Daddy sat dejected in the care beside him. There was shadow of sadness, and anguish on his face. He did not say anything to his son, but Mohit knew that his father was shocked and also angry to hear from the Doctor that his only son was a smoker.
As Mohit closed his eyes to shut out the outside image he went back to those days when he had started smoking only at the age of twelve. Suresh and Binu were his other friends who had encouraged him to try a cigarette. They used to meet every evening near the stadium. Though Suresh and Binu were not from the same school, Mohit had befriended them in a inter school competition. From then onwards they always met regularly. Unfortunately they were not the only friends. Their friend circle grew when other boys too became friendly with them. They used to sit and chat under a Bunyan tree and also play cricket together. Cricket actually extended the friend circle but while playing clean cricket, Mohit got into the habit of smoking unawares. At first it was a curiosity, then developed into a challenge among the friends and then smoking became the mark of manliness. Mohit wanted at any cost to be counted a Man so he regularly smoked with his friends. Before going home he would eat a strong flavor chocolate in order to camouflage the cigarette odor. Mohit always thought he was very smart because he could fool his mother and father. Before long, Mohit became an ardent follower and slave of Smoking. He realized that without cigarette he was not bale to concentrate in anything. His pocket money seemed very less for his expenses.
On the way to deceive his parents, Mohit actually was being deceived himself.
What he thought was smartness, was actually destroying his health. His bad health now stood as a barrier for him. He was not certain about his future. His dream to join the school of Defense lay shattered all because of a tiny yielding to the deception. With a wreaked health, and not able to join in the Defense Academy would he be now counted as a Man? Now as he sat on the car, he was realizing that indeed he has been deceived
But who was the deceiver? Was it his friend circle, was it the cigarette or was Mohit himself?
