A survey of nearly 300 US medical providers revealed that many were open to helping children with cancer access medical marijuana (MM).
However, most of the providers surveyed did not know state-specific regulations pertaining to MM.
Providers who were legally eligible to certify (ETC) for MM were less open to endorsing its use.
The lack of standards on formulations, dosing, and potency of MM was identified as the greatest barrier to recommending MM for children with cancer.
Kelly Michelson, MD, of Ann & Robert H. Lurie Children’s Hospital of Chicago in Illinois, and her colleagues reported these findings in Pediatrics.
The researchers used a 32-item survey to assess MM practices, knowledge, attitudes, and barriers for pediatric oncology providers in Illinois, Massachusetts, and Washington.
The survey was sent to providers at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, Seattle Children’s Cancer and Blood Disorders Center, and Lurie Children’s Center for Cancer and Blood Disorders.
There were 288 respondents, and 33% were legally ETC for MM. Eighty-six percent of ETC providers were physicians, and 14% were nurse practitioners or physician assistants.
Of the non-ETC providers, 89% were nurses, 8% were nurse practitioners or physician assistants, 2% were psychosocial providers, and 2% were “other” providers.
Thirty percent of all providers said they had received at least 1 request for MM in the previous month. And 14% of these providers facilitated patient access to MM.
Ninety-two percent of providers said they were willing to help pediatric cancer patients access MM. Fifty-seven percent of providers approved of patients smoking MM, 89% approved of oral formulations, 67% approved of using MM as cancer-directed therapy, and 92% approved of using MM to manage symptoms.
Fifty-nine percent of providers knew that MM is against federal laws, and 86% knew that their state had legalized MM, but only 5% knew state-specific regulations.
ETC providers were less likely to report willingness to help patients access MM. These providers were also less likely to approve of MM use by smoking, oral formulations, as cancer-directed therapy, or to manage symptoms.
“It is not surprising that providers who are eligible to certify for medical marijuana were more cautious about recommending it, given that their licensure could be jeopardized due to federal prohibition,” Dr Michelson said.
“Institutional policies also may have influenced their attitudes. Lurie Children’s, for example, prohibits pediatric providers from facilitating medical marijuana access in accordance with the federal law, even though it is legal in Illinois.”
Most providers considered MM more permissible for use in children with advanced cancer or near the end of life than in earlier stages of cancer treatment. This is consistent with the current American Academy of Pediatrics position that sanctions MM use for “children with life-limiting or seriously debilitating conditions.”
Only 2% of providers reported that MM was never appropriate for a child with cancer.
Most providers (63%) were not concerned about substance abuse in children who receive MM or about being prosecuted for helping patients access MM (80%).
The greatest concern (listed by 46% of providers) was the absence of standards around prescribing MM to children with cancer.
“In addition to unclear dosage guidelines, the lack of high quality scientific data that medical marijuana benefits outweigh possible harm is a huge concern for providers accustomed to evidence-based practice,” Dr Michelson said. “We need rigorously designed clinical trials on the use of medical marijuana in children with cancer.”
