Not all addictions are chemical. But surely, it is all about mental. Any pattern of behavior that leads to a pleasure, will be repeated by human minds. Positive reinforcement. This is technical addiction. Opium and TV act same as addictive agent.
When you watch TV or any passive entertainment medium, brain activity switches from the left brain to the right hemisphere. In fact, as per research, right brain is twice as active as the left. I call this a neurological anomaly.
The crossover of thoughts from left to right brain, releases endorphins, a neurochemical occurring naturally in the brain and having analgesic properties. i.e. Capable of relieving pain.
So every time you watch Television, or kids watch it, or play video game or surf internet videos, flood of endorphins releases from the neural gates. Endorphins are same chemical that drug addicts consume for artificial pleasure.
All activities that releases endorphins are habit-forming i.e. prone for addiction.
This the reason why Opium addict and TV addict or Smoking addict or alcohol cannot break the habit easily.
So if you really want to develop addiction, daru, cigar or TV are not good habits. They accelerates your right brain chaos and left methodical brain becomes useless. This leads to vicious cycle of lethargy, procrastination, withdrawal symptoms.
Find out activity that uses both right and left brain. There should be balance of chemical communication between two parts of the brain. TV fails this criteria. Cinema too. Video games too. Epic failures.
So what to do?
Play. Go, play with children. Sports. Go play with friends. Any outdoor sport that demands rules following, methods to execute, timely decision, input processing and gut feeling (Both left and right brain usage), 30 minutes a day, is worth. Try it. My fav is kho-kho. Perfect game where one can use both left and right brain together.
And make sure while you are running, cycling, swimming or doing any physical activity in silo, you do not succumb to pleasure. Addiction of anything is not worth. Even if it is physical exercise. 
🙂 I know they are better than watching TV which shutdowns all other areas of the brain but still…addiction is addiction 🙂 misuse of brain
