How did nitrous get such a bad rep...?

My buddy won speed week or whatever they call the race where you drive from track to track. He raced a Chevy powered mustang with nitrous on it. He sold the car to another buddy with less experience and he messed up the next year at the first track and did good but didn’t win. That car is sold and I’m pretty sure they are both going turbo now. I wish I was younger and knew more about them. If so I would have one.
Like I was saying earlier my son's going to add a Roots blower to his turbocharged Honda and use nitrous to cool it down LOL... He'll catch Dad one day LOL unlike 318willrun still trying to catch his son:poke::D..
