text: do parents out there know about huffing, dusting, or sniffing? i found out last week my 15 yr old has been huffing chemicals to get high.  alot of parents i have spoken to about this have never heard of it.  20% of 8th graders have huffed. its very dangerous i have a friend that worked in a drug rehab clinic and he said he had a case were a good kid, good grades and football player, started to huff gasoline and within a few weeks the poor kid could barely tie his shoe. he had to be told to put on his shirt and how to put it on everyday. its very scary! its actually killing brain cells with each huff.
