One thing that happens when you inhale paint fumes is that you will get dizzy and light-headed. Most paint fumes are toxic and can be extremely harmful to the body. There are some paints, however, that are made to be non-toxic and will not harm you if inhaled. Some people inhale fumes on purpose to experience a high. Doing this can be extremely addictive and can result in a variety of physical problems, or even death.
