Summary

For this quantitative study, the investigators will collect data on human safety and side-effects of Cannabichromene (CBC) and whether CBC reduces blood inflammatory markers and Rheumatoid Arthritis (RA) disease activity. The participants will participate in an ABAB design with 2 doses of CBC across the A phases. They will attend 5 in-person clinic visits where they will have physical evaluations, complete self-report forms, and have blood drawn for the following tests: hs-CRP, ESR, IL-6, TNF, Complete Blood Count \[CBC\], and CMP.

Conditions

  • Arthritis, Rheumatoid

Interventions

DRUG

Cannabichromene

Participants will be assigned (using block randomization) to begin with one of the two study doses of CBC (400mg or 600mg). Participants will be blinded to dose. They will be asked to take half of their dose in the morning and half in the evening. Participants will be administered dose one for eight weeks. After this, participants will have a two-week timeframe where they will be asked not to take any study medication and to continue refraining from cannabis use, thus providing a washout period. Then, at visit three, they will receive dose two and will take it for eight weeks, concluding the study with another two-week washout period. At each clinic visit participants will complete assessments (self-report and physical examination), urine, and blood samples.
