About this trial
The overall objectives of this study are to investigate the efficacy of extended cannabis treatment to reduce patient exposure to prescription opioids through its use 1) as a non-opioid analgesic treatment, and 2) as a therapy for reducing high-dose opioid use in patients with chronic spine pain.

Trial outcomes
Primary outcomes
Change in chronic pain as measured by the Visual Analog Scale (VAS) for pain
The Visual Analog Scale (VAS) for pain is a 0-100mm visual scale anchored by "no pain" and "worst possible pain".
Change in opioid dose as measured in morphine milligram equivalents (MME)
Secondary outcomes
Study Drug Tolerability as measured by study drug use
study drug dose, frequency
Study Drug Tolerability as measured by side effects
Change in spine-related disability and quality of life as measured on the NIH Patient Reported Outcomes Measurement System (PROMIS)-29
The NIH Patient Reported Outcomes Measurement System (PROMIS)-29 is a collection of 4-item short forms assessing anxiety, depression, fatigue, pain interference, physical function, sleep disturbance, and ability to participate in social roles and activities as well as a single pain intensity item.
Change in spine-related disability and quality of life as measured on the NIH Task Force on Research Standards for Chronic Low-Back/Neck Pain Minimal Dataset
The NIH Task Force on Research Standards for Chronic Low-Back Pain Minimal Dataset (and the modified Dataset for neck pain) assesses the influence of back/neck pain on physical function, emotional health, sleep, everyday activities.
