High VAS assesses the effect experienced by the participant on a 100-point unipolar VAS, where responses are unidirectional and range from a response of 'none' (score of 0) to 'extremely' (score of 100).

High: Peak Effect (Emax)

Time Frame: pre-dose, 5 min, 15 min, 30 min, 45 min, 1, 1.5, 2, 3, 4, 6, 8, 12, 24 h post-dose

Time Frame: 5 min, 15 min, 30 min, 45 min, 1, 1.5, 2, 3, 4, 6, 8, 12, 24 h post-dose

Drug liking assesses the degree that a participant likes a drug effect at the time the question is being asked (that is, at the moment). It is scored using a 100-point bipolar visual analogue scale (VAS) anchored in the center with a neutral anchor of
