Outcome Measures

Primary Outcomes (4)

  • Drug Effect Questionnaire - Stimulatory Effects

    Drug Effects Questionnaire was used to assess participants. The DEQ is consist of 10 items measured on a 1 to 100 visual analog scale, ranging from "not at all" to "extremely.". These ratings were then averaged to create three domain scores reflecting 1) stimulatory effects (average of "feel stimulated", "feel drug effects" and "feel high"), 2) pleasurable effects (average of "like", "feel good " and "want more"), and 3) aversive effects (average of "feel anxious", "feel down" and "feel bad"). Head rush was also assessed. Scores on the subscales range from 0 - 100 where 0 is the measure of least impactful 'effect'.

    Following 2 weeks of smoking, the procedure took over 3 hours, with measured effects at 2.5 minutes, 5 minutes and 10 minutes

  • Drug Effect Questionnaire - Pleasure Effect

    Drug Effects Questionnaire was used to assess participants. The DEQ is consist of 10 items measured on a 1 to 100 visual analog scale, ranging from "not at all" to "extremely.". These ratings were then averaged to create three domain scores reflecting: 1) stimulatory effects (average of "feel stimulated", "feel drug effects" and "feel high"), 2) pleasurable effects (average of "like", "feel good " and "want more"), and 3) aversive effects (average of "feel anxious", "feel down" and "feel bad"). Head rush was also assessed. Scores on the subscales range from 0 - 100 where 0 is the measure of least impactful 'effect'.

    Following 2 weeks of smoking, the procedure took over 3 hours, with measured effects at 2.5 minutes, 5 minutes and 10 minutes

  • Drug Effect Questionnaire - Aversive Effect

These ratings were then averaged to create three domain scores reflecting: 1) stimulatory effects (average of "feel stimulated", "feel drug effects" and "feel high"), 2) pleasurable effects (average of "like", "feel good " and "want more"), and 3) aversive effects (average of "feel anxious", "feel down" and "feel bad").

  • Drug Effect Questionnaire - Head Rush

    Drug Effects Questionnaire was used to assess participants. The DEQ is consist of 10 items measured on a 1 to 100 visual analog scale, ranging from "not at all" to "extremely.". These ratings were then averaged to create three domain scores reflecting: 1) stimulatory effects (average of "feel stimulated", "feel drug effects" and "feel high"), 2) pleasurable effects (average of "like", "feel good " and "want more"), and 3) aversive effects (average of "feel anxious", "feel down" and "feel bad"). Head rush was also assessed. Scores on all subscales, including Head Rush scale, range from 0 - 100 where lower scores indicate less head rush.

    Following 2 weeks of smoking, the procedure took over 3 hours, with measured effects at 2.5 minutes, 5 minutes and 10 minutes

CROSSOVER
Model Details: subjects will be unblinded to smoking menthol or non menthol for two weeks before each test session. Each session will include 3 infusions in the same order: nicotine (1 mg per 70 kg body weight) delivered over 5 minutes, saline and nicotine (1 mg/ 70 kg) delivered over 2.5 minutes. Once the participants complete the test session, participants will be crossed-over to the alternative treatment.
