Correction to Alcohol limit for drink driving should be much lower
Correction to Lithium and motor vehicle crashes
We inadvertently introduced confusion over the blood alcohol concentrations in this letter by Ediriweera B R Desapriya (10 April, p 895). Near the start of the second paragraph, the range should be 0.8 mg/ml to 1.0 mg/ml. The legal limit cited later in that paragraph is 0.8 mg/ml, and the risk of a crash increases above a concentration of 0.2 mg/ml. In the final paragraph, the concentration should again have been cited in mg/ml (as 0.8 mg/ml).
