THC Effects on Glucose in Type 2 Diabetes
What this study is about
This study will examine the effects THC has on Glucose Metabolism and Endothelial Functioning in participants with Type 2 Diabetes. The participants will complete blood tests and tests to measure energy expenditure, CVD risks, and glucose metabolism. These tests will be performed prior to start of treatment and again after 2-weeks of treatment with the THC or placebo.

- Male subjects must be willing to use clinically acceptable method of contraception during the entire study.
- Have a clinical diagnosis of Type 2 Diabetes on a stable medication regimen for at least 3 months.
- BMI \> 25 kg/m2).
- HbA1c \< 10%).
- Negative urine toxicology result at screening visit.
- Able to provide written informed consent approved by an Institutional Review Board (IRB).
Exclusion criteria
- History or presence of any clinically significant illness, as detected by history, physical examination, and/or laboratory tests, that might put the participant at increased risk of adverse events (e.g., history of psychotic disorder, clinically significant mood and/or anxiety disorder, liver, or renal disease).
- No prior history of myocardial infarction, stroke or heart failure.
- Whole blood donation of 1 pint (500 mL) within 8 weeks prior to Screening. Donations of plasma, packed RBCs, platelets or quantities less than 500 mL are allowed at investigator discretion.
- Hemoglobin \< 9g/dL.
- Liver enzymes ≥ 2 times upper normal limit and/or clinical signs/symptoms consistent with liver disease, including but not limited to nausea, vomiting, jaundice, itching, abdominal pain, or edema.
- History of clinically significant adverse events associated with cannabis intoxication (e.g., severe anxiety and panic, paranoia and psychosis, sustained tachycardia, or severe hypotension).
- History of seizures, head trauma, or other history of CNS insult that could predispose the participant to seizures.
- Use of any THC containing products within 30 days prior to the screening visit.
- Current use of tobacco products.
- Individuals who are pregnant or lactating/breastfeeding.
- Current use of insulin to treat Type 2 Diabetes.
- Unable or unwilling to follow the study protocol or who are non-compliant with screening appointments or study visits.
- Any other condition(s) that might reduce the chance of obtaining study data, or that might cause safety concerns, or that might compromise the ability to give truly informed consent.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
