CBD
The starting dose will be 1 capsule per day (50 mg CBD) taken orally. The dose will be gradually increased over the first four weeks, based on patient assessment, up to a maximum of five capsules per day (250 mg CBD) in divided doses. Once the dose that maximizes potential therapeutic effects while minimizing adverse effects has been determined, it will be maintained for the remaining four weeks of the trial.
THC
The starting dose will be 1 capsule per day (3 mg THC) taken orally. The dose will be gradually increased over the first four weeks, based on patient assessment, up to a maximum of five capsules per day (15 mg THC) in divided doses. Once the dose that maximizes potential therapeutic effects while minimizing adverse effects has been determined, it will be maintained for the remaining four weeks of the trial.
Placebo
The starting dose will be 1 capsule per day taken orally. The dose will be gradually increased over the first four weeks, based on patient assessment, up to a maximum of five capsules per day in divided doses. Once the dose that maximizes potential therapeutic effects while minimizing adverse effects has been determined, it will be maintained for the remaining four weeks of the trial.
