Official title

Cannabinoid-Based Therapy and Approaches to Quantify Pain in Sickle Cell Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Our primary objective is to assess whether inhaling vaporized cannabis ameliorates chronic pain in patients with sickle cell disease (SCD). As these patients will all be on chronic opioid analgesics, the investigators will also assess the possible synergistic affect between inhaled cannabis and opioids. The investigators will also assess the clinical safety of the concomitant use of cannabinoids and these opioids in patients with SCD by monitoring the short-term side effects associated with combined therapy. Finally, the investigators will evaluate the short-term effects of inhaled cannabis on markers of inflammation and disease progression in patients with SCD. Hypotheses are as follows: 1. Inhaled cannabis will significantly reduce chronic pain in patients with SCD. 2. Inhaled cannabis will significantly alter the short-term side effects experienced by patients who take opioids for SCD. 3. Inhaled cannabis will significantly alter markers of inflammation and disease progression in patients with SCD compared to placebo.
