Effect of hashish on vigilance performance.
A group of 11 hashish users were compared with 11 controls on a visual sustained attention (vigilance) task. Analysis indicated that hashish use affected subjects' sensitivity. Subjects who used hashish responded in an indiscriminate manner, making more false alarms (8.7) than controls (2.6). The importance of vigilance in the assessment of adverse effects of hashish is discussed.
