Primary Outcome Measures

Name	Time	Method
Number of participants with altered cognitive function at 40mins post-dose	40mins Post-dose	This outcome measure is assessed by the number of participants whose scores on a range of cognitive tasks (word and picture recall and recognition, serial 3s and 7s subtractions, rapid visual information processing (RVIP), N-Back (3-Back version), Stroop and numeric working memory) differed from the baseline to 40min post-dose scores.
Number of participants with altered cognitive function at 2.5hrs post-dose	2.5hrs post-dose	This outcome measure is assessed by the number of participants whose scores on a range of cognitive tasks (word and picture recall and recognition, serial 3s and 7s subtractions, rapid visual information processing (RVIP), N-Back (3-Back version), Stroop and numeric working memory) differed from baseline to the 2.5hr post-dose scores.
Number of participants with altered cognitive function at 4hrs post-dose	4hrs post-dose	This outcome measure is assessed by the number of participants whose scores on a range of cognitive tasks (word and picture recall and recognition, serial 3s and 7s subtractions, rapid visual information processing (RVIP), N-Back (3-Back version), Stroop and numeric working memory) differed from baseline to the 4hr post-dose scores.
Number of participants with altered cognitive function at 6hrs post-dose	6hrs post-dose	This outcome measure is assessed by the number of participants whose scores on a range of cognitive tasks (word and picture recall and recognition, serial 3s and 7s subtractions, rapid visual information processing (RVIP), N-Back (3-Back version), Stroop and numeric working memory) differed from baseline to the 6hr post-dose scores.

Secondary Outcome Measures

Name	Time	Method
Number of participants with altered mood at 40mins post-dose.	40mins post-dose	This outcome was assessed by the number of participants whose baseline mood scores (as assessed by the Bond-Lader mood scale which categorises 'alert', 'content' and 'calm') differed from the 40mins post-dose scores.
Number of participants with altered mood at 2.5hrs post-dose	2.5hrs post-dose	This outcome was assessed by the number of participants whose baseline mood scores (as assessed by the Bond-Lader mood scale which categorises 'alert', 'content' and 'calm') differed from the 2.5hrs post-dose scores.
Number of participants with altered mood at 4hrs post-dose	4hrs pos-dose	This outcome was assessed by the number of participants whose baseline mood scores (as assessed by the Bond-Lader mood scale which categorises 'alert', 'content' and 'calm') differed from the 4hrs post-dose scores.
Number of participants with altered mood at 6hrs post-dose	6hrs post-dose	This outcome was assessed by the number of participants whose baseline mood scores (as assessed by the Bond-Lader mood scale which categorises 'alert', 'content' and 'calm') differed from the 6hrs post-dose scores.
