Characteristics of Individuals with Spinal Cord Injury Who Use Cannabis for Therapeutic Purposes.

People with spinal cord injury (SCI) are accessing cannabis for therapeutic purposes (CTP), the use of which has been legalized in more than 20 states. In the past, illicit marijuana use had positive correlations with other health risk behaviors. It is not known whether access to CTP has shifted patterns of use and altered health outcomes. To describe the self-reported patterns of CTP use among individuals with SCI and correlations with health behaviors and health indicators. Secondary analysis of data from a cross-sectional study involving community-dwelling individuals with chronic SCI and neurogenic bladder and bowel, at least 5 years post injury. Data were collected via structured interviews. 92.2% of the current sample ( = 244) lived in states that, at the time of the study, permitted the use of CTP. 22.5% reported using CTP at least monthly to relieve pain (70.4%) and spasticity (46.3%). Of those 54 participants, 52.7% were daily users. Whereas 23.0% of non-CTP users endorsed having prescriptions for at least one opioid-based medication, 38.1% of CTP users did so, suggesting that CTP use does not mitigate opioid use. Users were more likely to be single and live alone, report more bladder complications, and perceive their psychosocial functioning as more compromised than non-users. A relatively large percentage of individuals with chronic SCI appear to use CTP on a regular basis. Results suggest that they may be more vulnerable to complications and to risk factors for substance use disorders in SCI, such as social isolation. Although the generalizability of these findings is limited by the sampling strategies and the eligibility criteria of the larger study, CTP use should be assessed and considered when planning health interventions.
