Inhalants & GHB
Uni of Notts, Addiction & The Brain, first year
| Question | Answer |
|---|---|
| Inhalants | Any volatile substance (usually household items) that are vaporised & inhaled to enter the blood stream where it will cross the blood-brain barrier & act on the brain |
| Acute exposure | Euphoria, light-headedness, feeling of body lightness, sedation, hallucinations, delusions, Sudden Sniffing Death Syndrome (SSDS) |
| Chronic exposure | Not well documented but studies show lesions in white matter in the brain & subcortical matter in some important structures |
| Sir Humphry Davy | Chemist who experimented with inhaling various substances (such as nitrous oxide) at parties with friends to document their experiences of the substances, this led inhalants to be used in medical & dental procedures |
| General neural mechanisms of inhalants | Volatile lipophilic molecules can interact hydrophobically with receptor subunits: increasing stability & conductance of GABAa & D2 domains while destabilising interactions between NMDA receptor subunits |
