NCT06638996

Brief Summary

The purpose of this study is to examine the acute effects of cannabigerol (CBG) on various psychological (e.g., anxiety, stress, mood, memory, impairment, intoxication, side effects) and physiological (blood pressure, cortisol, heart rate variability, electrodermal activity, pain tolerance, temperature) outcomes. Further, potential side effects of CBG (sleepiness/fatigue, dry mouth/eyes, increased appetite, and dizziness nausea) will be assessed. As such, the study is focused on better understanding some of the potentially beneficial and detrimental effects of CBG on humans.

Outcome Measures

Primary Outcomes (11)

  • Anxiety

    Anxiety will be assessed along a 0 to 10 rating scale at baseline (T0), \~40 minutes after ingesting placebo or CBG (T1), after the stress test (T2), and after the memory tests (T3). Change scores from baseline to each time point will be examined.

    Anxiety ratings will occur within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • Stress

    Stress will be assessed along a 0 to 10 rating scale at baseline (T0), \~40 minutes after ingesting placebo or CBG (T1), after the stress test (T2), and after the memory tests (T3). Change scores from baseline to each time point will be examined.

    Stress ratings will occur within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • Mood

    Mood will be assessed along a 0 to 10 rating scale at baseline (T0), \~40 minutes after ingesting placebo or CBG (T1), after the stress test (T2), and after the memory tests (T3). Change scores from baseline to each time point will be examined.

    Mood ratings will occur within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • Salivary Cortisol

    Salivary Cortisol will be collected using Salivettes at baseline (T0), \~40 minutes after ingesting placebo or CBG (T1), after the stress test (T2), and after memory the memory tests (T3). Change scores from baseline to each time point will be examined.

    Saliva samples will be collected within the 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • Electrodermal Activity

    Electrodermal Activity will be assessed continuously using an Embrace wristband device from baseline to the end of the study. Primary points of interest include baseline (T0), after ingesting placebo or CBG (T1), after the stress test (T2), and after the memory tests (T3).

    Electrodermal Activity will be measured continuously for the duration of the 2.5 hour session for each session with sessions scheduled approximately one week apart

  • Heart Rate/Heart Rate Variability

    Heart rate/heart rate variability will be assessed continuously using an Embrace wristband device from baseline to the end of the study. Primary points of interest include baseline (T0), after ingesting placebo or CBG (T1), after the stress test (T2), and after the memory tests (T3).

    Heart Rate/Heart Rate Variability will be assessed continuously for the duration of the 2.5 hour session with sessions scheduled approximately one week apart

  • Blood Pressure

    Blood Pressure will be assessed at baseline (T0), \~40 minutes after ingesting placebo or CBG (T1), after the stress test (T2), and after the memory tests (T3). Change scores from baseline to each time point will be examined.

    Blood Pressure will be obtained multiple times throughout the 2.5 hour session for each session with sessions scheduled approximately one week apart

  • Pain Tolerance

    Pain tolerance will be assessed by computing the duration of time they keep their hand in the cold pressor on each of the three cold pressor trials.

    Pain tolerance will be assessed within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • Verbal Memory

    Participants will complete the California Verbal Learning Test

    Participants will complete this test within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • Short-Term/Working Memory

    Participants will complete the Digit Span Forwards and Digit Span Backwards Tests

    Participants will complete this test within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • False Memory

    Participants will complete the Deese-Roediger-McDermott paradigm.

    Participants will complete this test within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart

Secondary Outcomes (3)

  • Impairment

    Participants will complete the DRUID app within the 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • Subjective Drug Effects

    Subjective drug effect ratings will occur within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart

  • Side Effects

    Side effect ratings will occur within a 2.5 hour time frame for each session with sessions scheduled approximately one week apart
