just painting your nails is okay but If your trying to get high from it, it kills your brain cell, and they won't grow back, in short..it will make you dumb.. and can even make you pee on your self stuff like that it can and will mess up your motro skills like talking and also forgetting stuff..
Yes. Nail polish is an inhalant. If you breathe it in too much, it can kill brain cells and eventually kill you if you don't get any fresh air. But don't worry, breathing it in a little won't kill you.
