how many cigarettes do you need to be addicted to them?!

It depends on your personality and morality on the consumption of drugs. For example, you may have an addictive personality and naturally chain smoke. Outside of that, it depends on how quickly you consume those cigarettes. It could take around a pack or maybe a couple.

Personally, I've smoked both occasionally when I drank and for weeks at a time, but I never felt the need for or want a cigarette. Honestly, I only did it because all my friends in college did and I wanted to fit in and socialize. (This was when I was young and stupid, I know.) On the other hand, I've seen friends who get extremely moody and close to having a panic attack because they needed a cigarette. But I've heard a pack or two will get you addicted.

For some it takes as little as one, so it is best you not start. In addition to the
addiction factor, use easily contributes to health risks which you cannot repair.

Depends the person
