A far as I don't understand, there's no free ride.
When you start getting nicotine you get a hit and it helps to focus, but at the same time it meddles with your fine tuned system of neuromediators so it lowers your base focus ability. Later you have to get another hit just to regain what used to be your base before.
It's called addiction. 

 Yea except I don’t do it often so it really doesn’t feel like that to me 

 This is the way.
This is exactly how I got addicted man. 

 Lmao 😂
