In a letter April 26 to House and Senate members, Pates said a comprehensive bill was needed to "give Iowans the ability to produce a safe and consistent treatment as well as provide a legal avenue for physicians to recommend it to those who are in need."
It is legal in Iowa for people who suffer from epilepsy to use cannabis oil under a 2014 law approved by legislators. No other illnesses are covered by the law.
However, Iowans with epilepsy cannot legally obtain the medical cannabis in the state because legislators have not approved allowing for its production and distribution. Patients also cannot bring medical cannabis from other states without breaking federal laws.
Pates reached his decision after visiting several people suffering from chronic, painful conditions who would benefit significantly from medical cannabis and having been contacted by several Iowa legislators. In the letter, he wrote that making the drug available for those who need it for medicinal purposes is a humanitarian issue, particularly during this Jubilee Year of Mercy initiated by Pope Francis.
"As the bishop of the Catholic Diocese of Des Moines, I join the 78 per cent of Iowans who believe that medical cannabis should be legally produced, distributed and possessed in Iowa for humanitarian purposes to provide relief for those who are sick and suffering," he wrote.
A recent Des Moines Register/Mediacom Iowa Poll showed 78 per cent of adults in Iowa approve of the use of medical marijuana.
"I support this extension of palliative care among this sector of hurting people," Pates said.
The legislative proposals have failed so far and legislators have engaged in intense debates on the issue as the final days of the 2016 session wind down. One proposal would have expanded the number of illnesses for which cannabis could have been used. Another would have allowed the state to grow cannabis and produce an oil for medicinal purposes.
"I believe now is the time to help suffering Iowans and their families get legal access to this medicine," the bishop concluded in his letter.
Twenty-four states allow cannabis oil for medicinal purposes.
