I think all the people I knew who ever did inhalants like glue or aerosols were adversely affected by it. Their mental functioning is nothing like it used to be. When you have a conversation with them they talk slow, they're not too bright (any more) and they sound dopey and act like they're not quite 'with it'. If you spoke to one of them, you would automatically assume that they were a drug addict even though they don't abuse those substances any more. There's definitely a lot of brain damage caused by inhalants.
