Hydrocarbons are a diverse group of organic chemicals that have general sedating effects, like ethanol. Hence there is a risk they may be abused. Occasionally they may be ingested in attempted self-harm.

Of particular concern are hydrocarbons that have systemic toxicity.

The toxic alcohols include methanol and ethylene glycol and, to a lesser extent, ethanol and isopropanol. In addition to their CNS effects, they are metabolised into toxic compounds and, in the case of methanol and ethylene glycol, can be lethal in small amounts.

Other hydrocarbons with inherent systemic toxicity can be remembered by the acronym CHAMP:

• Camphor
• Halogenated hydrocarbons
• Aromatic hydrocarbons
• Metal additives to hydrocarbons
• Pesticides dissolved in a hydrocarbon solvent, eg most organophosphates
