Inhalants are among the worst substances one can abuse. Obviously Fentanyl is the hot button chemical that is most covered by the media and rightfully so, due to its prevalence and its mortality rate. Inhalants, however, are extremely problematic and are abused more regularly than most people are aware of. They are used in conjunction with other drugs or when other drugs can't obtained. The psychosis caused by inhalants is worse than the psychosis caused by Crystal Meth. A large portion of EDP's in urban settings are at least in part due to self medication with crystal meth and or inhalants. There might be an underlying mental illness but there are many cases that their state is just due to abuse of the substance and the toll it takes on the mind.
