  • Person has used cannabis, synthetic cannabinoid or cannabinoid analogue (e.g., dronabinol, nabilone), synthetic cannabinoid receptor agonist (e.g., spice, K2), or any CBD- or delta-9- tetrahydrocannabinol (THC)-containing product within 30 days of screening or during the study.
  • Person is currently prescribed medications with likely THC- or CBD- interactions (e.g., warfarin, clobazam, valproic acid, phenobarbital, mechanistic target of rapamycin \[mTOR\] inhibitors, oral tacrolimus, St. John's wort; Epidiolex).
  • Person is currently prescribed and using a medication used in the treatment of anxiety disorders (e.g., selective serotonin uptake inhibitors, venlafaxine, buspirone, benzodiazepines, hydroxyzine, tiagabine, gabapentin, valproate, lamotrigine, topiramate, beta blockers, clonidine, guanfacine, atypical antipsychotics);

  • Person has received formal training to tolerate elevated levels of CO2 or bodily arousal (such as free diver training or interoceptive exposure-based treatment).
  • Any other clinically significant disease or disorder or abnormal findings during screening or the baseline assessment that, in the opinion of the investigator, may either put the person at risk because of participation in the study, may confound the results of the study, or affect the person's ability to participate in the study.
  • Person has an acute or progressive disease that is likely to interfere with the objectives of the study, or the ability to adhere to protocol requirements.
  • Woman of childbearing potential, unless she has not engaged in vaginal intercourse or she has used effective contraception when doing so (for example, oral contraception, double barrier, intra-uterine device) for at least 30 days prior to the study.
