Study Finds Most Cancer Survivors Who Used Marijuana Reported ‘Great Degree Of Symptomatic Improvement’

A new study of 1,886 cancer survivors found that nearly half either currently or previously used cannabis, with most of those who used marijuana after their diagnoses reporting that it was to manage symptoms like sleep disturbances and pain. About a fifth of cancer survivors, it found, “currently use cannabis for symptomatic relief while undergoing active cancer treatment.”

Published late last month in the Journal of Cancer Survivorship, the study says that the prevalence of cannabis use among cancer survivors “was notable, with most reporting a great degree of symptomatic improvement for the specified reason for use.”

Of all participants, 17.4 percent were current cannabis users, 30.5 percent were former users and 52.2 percent said they’d never used marijuana. Of the 510 respondents (27 percent) who used cannabis after their cancer diagnosis, 60 percent said they used it to manage sleep disturbances, followed by pain (51 percent), stress (44 percent), nausea (33 percent) and mood disorders or depression (32 percent).

“Cannabis use among cancer survivors is noteworthy, with a predominant proportion of survivors reporting a substantial degree of amelioration of symptoms.”

“Also, about a fifth (91/510) of cancer survivors used cannabis to treat their cancer,” the study said.

Majorities of patients said the use of marijuana was effective at treating symptoms. Among those using it to treat nausea, for example, 73.6 percent said it was effective “to a great extent,” with another 24.4 percent saying it was “somewhat” effective. Only 1.9 percent said it had “very little” efficacy, and virtually none said it was “not at all” effective.

Similar findings occurred around depression, appetite, pain, sleep stress and coping with illness generally. In each instance, more than half of respondents said cannabis was helpful “to a great extent,” while between half and a quarter said it was “somewhat” effective. Small fractions, at most around 5 percent, reported “very little” benefit or none at all.

In terms of treating cancer itself, responses were only slightly less enthusiastic. Just under half (47.7 percent) called marijuana effective “to a great extent,” 34.5 percent said it was “somewhat” helpful, 13.8 percent said it offered “very little” benefit and just 4 percent said it helped “not at all.”

“Of the survivors who used cannabis to improve nausea and vomiting, 74% (131/179) perceived it helped to a great extent.”

The four-author research team, at the University of Texas’s MD Anderson Cancer Center, also found that awareness of marijuana’s potential health hazards was quite low among respondents, with only about 1 in 10 reporting awareness of such risks when asked, “Were or are you aware of any potential health risks associated with cannabis/marijuana during your cancer treatment?”

“Only a few were aware of the health risks of cannabis use during cancer management,” the study says. “Of the 167 survivors who reported awareness of potential health risks from cannabis use, the awareness of adverse health risks associated with cannabis use was low: suicidal thoughts (5 percent), intense nausea and vomiting (6 percent), depression (11 percent), anxiety (14 percent), breathing problems (31 percent), and interaction with cancer drugs (35 percent).”

In light of the likelihood that some people might be using cannabis to treat symptoms despite not fully knowing the drug’s possible side effects, the study encourages that medical guidance welcome discussion of therapeutic marijuana into a patient’s broader course of treatment.

“With most survivors reporting benefits from cannabis use in cancer management, there is a need for more studies to strengthen current evidence on cannabis therapeutics,” it says. “Also, there is a need for policies, clear guidelines, and cannabis-based educational programs for healthcare providers and survivors on the use, benefits, and risks of cannabis in cancer management.”

“Healthcare providers should engage survivors in discussions regarding the current state of evidence on cannabis use during cancer treatment,” it adds, “to help them make informed decisions regarding their healthcare.”

The study is the latest in a growing body of research looking into how cannabis is being used—and how it might be used in the future—to manage cancer symptoms. In late October, for example the University of Buffalo announced that one of its psychiatrists had received a $3.2 million grant from the National Institutes of Health’s (NIH) National Cancer Institute to fund a yearlong study into how immunotherapy, a common cancer treatment, is affected by patients’ cannabis use.

In May of last year, meanwhile a University of Colorado study, using marijuana products from state-licensed dispensaries, found that chemotherapy patients who used cannabis regularly over a two-week period reported not only reduced pain but also clearer thinking.

The American Medical Association (AMA) also published research in late 2022 that connected state cannabis legalization with reduced opioid prescribing for certain cancer patients.

The new study comes as patients, researchers and everyday observers await action from the Drug Enforcement Administration (DEA) on a pending review of marijuana’s scheduling status under the federal Controlled Substances Act. The Department of Health and Human Services (HHS) recommended last August that DEA reschedule cannabis, reportedly to Schedule III.

The move would still not legalize state medical marijuana or adult-use cannabis programs under federal law, though it would open the door to Food and Drug Administration (FDA) approval of cannabis-based drugs and increase profit for medical marijuana companies that currently can’t take standard business deductions under the federal tax code.

On Wednesday, DEA said in a brief letter to lawmakers about the rescheduling process that the agency reserves “the final authority” to make any scheduling decision on marijuana, regardless of what HHS recommends.

“DEA has the final authority to schedule, reschedule, or deschedule a drug under the Controlled Substances Act, after considering the relevant statutory and regulatory criteria and HHS’s scientific and medical evaluation,” the letter said. “DEA is now conducting its review.”
