Toxicology tests reveal drugs in US official's system

A number of drugs have been found in samples taken from a Wisconsin-based official who was arrested for driving under the influence.

State representative Jeff Wood's toxicology report showed two types of sedative and two anti-anxiety medications, as well as a large amount of a chemical commonly found in cough medicine.

According to the document, levels of dextromethorphan (DXM) in his system were eight times the recommended dosage, while other drugs were found to be within normal range.

The Wisconsin State Journal reports Wood told an Assembly ethics committee - who are currently scrutinising whether he should be expelled from legislature - that he had taken more of the DXM than was advised on the label.

An over-the-counter cough suppressant, the substance can cause visual and auditory hallucinations and has been described as "poor man's PCP", the news provider added.

Toxicology tests recently revealed Washington-based music teacher Geoff Gilbert had both alcohol and marijuana in his system when he was killed rear-ending a truck in fog.
