Brief Summary:
The goal of this study is to determine the feasibility of a human observational study of orally administered cannabis use among cancer patients.

Condition or disease
Solid Tumor, Adult

Detailed Description:
Tightly controlled experimental laboratory studies (e.g., clinical trials with randomization) using Cannabis products available in state-regulated markets are simply, at this point, not possible owing largely to federal law and the University requirements related to the Controlled Substances Act and Drug Free Schools and Communities Act. Because a traditional clinical trial design is not possible given the current federal status of Cannabis products, this investigator will use a patient-oriented, prospective observational design. Specifically, individuals who have already decided to try Cannabis for their cancer treatment-related symptoms will initiate use of an orally administered product they have selected. A research assistant will provide information on the range of edible cannabis products and basic information about their various cannabinoid profiles, approximate prices, and nearby locations where participants may choose to purchase their product. The participants will then purchase the product and decide how often and how much to use. This approach is consistent with federal law and supported by our preliminary and ongoing studies(1R01AT009541-01, 1R01DA044131-01, CDPHE2902, R01DA039707). Patients will take the product as they see fit, without any frequency or dosing instructions from study staff, for two weeks, at which time they will be scheduled for their session in our mobile pharmacology and phlebotomy lab (Ta1-Tc1) so that we may examine the acute effects of the product. The Mobile Lab session will take place at a location of their choosing up to 90 minutes drive-time away from the CUChange Lab. The final follow-up will be one month later via an online survey sent directly to the participant via email.

Group/Cohort
Oral Cannabis
This is an observational study of individuals who have already decided to try cannabis for their cancer treatment-related symptoms. A research assistant will provide information on the range of edible cannabis products and basic information about their various cannabinoid profiles, approximate prices, and nearby locations where participants may choose to purchase their product. Participants will then initiate use of an orally administered product they have selected and obtained. Participants will take the product as they see fit, without any frequency or dosing instructions from study staff, for two weeks.

Primary Outcome Measures :
  1. Likelihood of Accruing Participants: Feasibility of Enrollment [ Time Frame: 18 months ]
    Enroll a minimum of 30 patients and demonstrate reasonable compliance with study procedures within six months of active recruiting.


Other Outcome Measures:
  1. Amount of Interest [ Time Frame: 18 months ]
    Study officials will document how many patients contact the research team regarding their participation in the study

  2. Eligibility [ Time Frame: 18 months ]
    Study officials will document how many patients are and are not eligible to participate in the study.

  3. Enrollment [ Time Frame: 18 months ]
    Study officials will document how many patients actually proceed to enrollment in the study.

  4. Completion of Assessments [ Time Frame: Baseline to one month follow up, in an eighteen month time frame ]
    Study officials will document how many participants complete each assessment (baseline assessment, pre-acute cannabis use assessment, 1 hour post-acute cannabis use, 2 hour post-acute cannabis use, one month follow up assessment).

  5. Study Completion [ Time Frame: 18 months ]
    Study officials will document how many participants complete the study in its entirety.
