The effect of salbutamol on breath alcohol testing in asthmatics

Subjects suffering from asthma can occasionally experience difficulty in providing adequate breath samples for evidential breath alcohol testing devices and may therefore resort to the use of bronchodilators such as salbutamol to improve their respiration. Experiments showed that although salbutamol caused bronchodilation it did not affect breath alcohol levels of asthmatics who have been drinking. The blood:breath alcohol ratios obtained from asthmatics were within the normally recorded range before and after use of salbutamol. We conclude that the use of salbutamol by asthmatics does not affect the reliability of measurements made by evidential breath alcohol testing devices.
