Is this trial a fit for you?

Likely a good fit

Ideal candidates are males and females aged 21-70 with a stable Type 2 Diabetes diagnosis and a BMI over 25.

Probably not a fit

Patients with significant comorbid conditions or those with a history of psychotic disorders may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates how THC influences glucose metabolism and endothelial function in individuals diagnosed with Type 2 Diabetes. It employs a single-center, double-blind, placebo-controlled, cross-over design involving 30 participants who will receive either THC or a placebo over two-week treatment periods, separated by a four-week washout. Participants will undergo various assessments, including blood tests and evaluations of cardiovascular risks and energy expenditure, both before and after treatment. The study aims to provide insights into the metabolic effects of THC in this patient population.

Why it matters

Potential benefit: If successful, this study could lead to new therapeutic approaches for managing glucose levels in patients with Type 2 Diabetes.

How similar studies have gone: While studies on THC's effects on various health conditions exist, this specific approach to glucose metabolism in Type 2 Diabetes is relatively novel and has not been extensively tested.

* 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).

* 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.
