We are seeking participants who experience insomnia for a 6-week cross-over trial investigating the tolerability and effectiveness of Medicinal Cannabis (THC:CBD 10:15). Participation involves:

  1. 5 appointments of 1 hour duration at weekly intervals, either at NIIM or per phone.
  2. A control/run-in phase of 1 week, is followed by 2 weeks of treatment (active or placebo), 1 week wash-out, and 2 weeks of cross-over treatment (placebo or active).
  3. A series of questionnaires will be administered at each appointment.
  4. You will be required to wear a wrist activity tracker continuously for 6 weeks.
  5. You will be required to collect your saliva for cortisol and melatonin assessment 4 times around midnight at the end of weeks 1,3, 4 and 6.
  6. Willing not to drive a vehicle during 6 weeks of the study. Please note: Participants will have a 50:50 chance to be taking the active cannabis oil in the first or second intervention period.
