What This Study Found

41% of surveyed cancer patients used cannabis during active treatment. Among active users, 71.8% started before diagnosis. Stage 4 patients had higher use (60%). Top reasons during treatment: depression/mood, pain, enjoyment. 44.3% used at least daily. Most common cannabinoids: CBD (35.2%), Delta-8-THC (18.3%), CBD+THC ratio (14.1%). 12.7% were unsure what they consumed.

Key Numbers

385 patients (mean age 49.5, 53% male, 41.6% Hispanic/Latino). 41% used during treatment. 71.8% of treatment users started before diagnosis. Stage 4 use: 60%. Daily use: 44.3%. Unsure of cannabinoid content: 12.7%.

How They Did This

Survey of 385 adult cancer patients at an NCI-designated cancer center using a harmonized survey created with 11 other NCI centers. Cannabis use patterns, sources, and reasons compared between active treatment users and non-users.

Why This Research Matters

A significant portion of cancer patients use cannabis during treatment, often without clinician guidance. The finding that 12.7% did not know what cannabinoid they consumed highlights a safety gap.

The Bigger Picture

The high prevalence of cannabis use during cancer treatment, combined with lack of knowledge about specific products being consumed, points to a need for oncology teams to proactively discuss cannabis with patients and provide guidance on safe use.

What This Study Doesn't Tell Us

Single-center survey from an NCI center with high Hispanic/Latino representation may not generalize. Self-reported data. Cannot assess whether cannabis affected treatment outcomes. Cross-sectional design.

Questions This Raises

  • ?Does cannabis use during chemotherapy affect treatment efficacy or drug interactions?
  • ?Should oncology intake forms routinely screen for cannabis use and specific products?

Frequently Asked Questions

How many cancer patients use cannabis during treatment?

In this study, 41% of surveyed patients used cannabis during active treatment. Nearly half of those used it daily, and the majority had started using cannabis before their cancer diagnosis.

Do patients know what cannabis products they are using?

Not always. 12.7% of patients using cannabis during treatment were unsure what cannabinoid they were consuming, and products varied widely from CBD to Delta-8-THC to combination products.
