What This Study Found

Across 28 participants in focus groups, seven key themes emerged: efficacy, safety, stigma, cost, convenience, government/legal considerations, and interactions with healthcare providers. Themes were similar whether participants had or had not used medical cannabis, though emphasis varied. A major finding was that even current users had significant unanswered questions.

Key Numbers

28 participants across three focus groups. Seven key themes identified. Research questions were derived from identified themes to guide future patient-centered research.

How They Did This

Qualitative focus-group study with three participant groups: chronic pain patients who had used medical cannabis, chronic pain patients who had not, and people without chronic pain who used cannabis for other conditions. Used semi-structured facilitator questionnaire with thematic analysis via NVivo 12.

Why This Research Matters

Despite growing medical cannabis use for chronic pain, this study reveals that patients on both sides of the decision feel they lack adequate information to make informed choices, highlighting a gap between policy expansion and patient education.

The Bigger Picture

As medical cannabis programs expand, the gap between access and evidence-based guidance remains a central challenge. Patients are making treatment decisions without the information they need, and their healthcare providers often cannot fill those gaps.

What This Study Doesn't Tell Us

Small sample size (28 participants). Qualitative design provides depth but not generalizability. Convenience sampling may not capture the full range of patient perspectives.

Questions This Raises

  • ?How can healthcare providers be better equipped to counsel patients about medical cannabis?
  • ?What specific dosing and formulation research would most help patients make informed decisions?
