The World Health Organization has suggested that cannabis should be “rescheduled,” given the mounting evidence showing that the drug could prove beneficial in treating a number of health problems.
This marks a significant change in the WHO’s position, which for the last 60 years has said that cannabis should not be used in medicine, according to an article in the BMJ.
The WHO Expert Committee on Drug Dependence has recommended that cannabis resin and other marijuana products should be removed from the Schedule IV category of the 1961 U.N. Single Convention on Narcotic Drugs.
“Based on the evidence presented to it, the Committee say that cannabis plant and cannabis resin are not liable to produce the same ill-effects as other substances in the Schedule IV category,” the authors of the report wrote.
Because Schedule IV is the strictest category outlined in the 1961 Convention, it means scientists who want to investigate the plant in the search for potential therapies are severely restricted.
“Preparations of cannabis have shown therapeutic potential for treatment of pain and other medical conditions such as epilepsy and spasticity associated with multiple sclerosis,” the extract read. “In line with the above, cannabis and cannabis resin should be scheduled at a level of control that will prevent harm caused by cannabis use and at the same time will not act as a barrier to access and to research and development of cannabis-related preparation for medical use.”
Despite this, the Committee argued that due to the “high rates of public health problems arising from cannabis use,” it should continue to be included in Schedule I of the 1961 Convention.
The Committee also recommends that psychoactive compounds in cannabis, known as dronabinol and tetrahydrocannabinol—which are forms of THC—should be removed from the 1971 U.N. Convention on Psychotropic Substances and placed in Schedule I of the 1961 Convention instead. The idea behind this proposal is to simplify the classification of THC and cannabis products.
Furthermore, the Committee proposes that products made with a cannabis extract known as cannabidiol, which contain no more than 0.2 percent THC, should be removed from all international drug control conventions.
“Cannabidiol is found in cannabis and cannabis resin but does not have psychoactive properties and has no potential for abuse and no potential to produce dependence,” the proposals read. “It does not have significant ill-effects. Cannabidiol has been shown to be effective in the management of certain treatment-resistant, childhood-onset epilepsy disorders. It was approved for this use in the United States in 2018 and is currently under consideration for approval by the EU.”
According to Michael Krawitz, global policy adviser at the nonprofit advocacy organization FAAAT which campaigns for the medical use of the cannabis, the placement of the drug in the 1961 treaty was a “terrible injustice.”
“The WHO has gone a long way towards setting the record straight,” he said in comments provided to Newsweek. “It is time for us all to support the World Health Organization’s recommendations and ensure politics don’t trump science. Advocates thank the WHO Experts for their work, and WHO leadership for consistently defending the medical needs of our world.”
According to the FAAAT, the latest news has significant implications for the future role of cannabis in the field of medicine.
Kenzi Riboulet-Zemouli, head of research at FAAAT, told Newsweek: “If this outcome is not the end of the road in the struggle for access and availability of cannabis-based medicines—and I hope that nobody expected that, as the mandate of WHO has always been known to be limited—it gives an important positive signal to countries.”
He added: “If the recommendations of the WHO are adopted, it will substantially increase the normalization and development of access, availability, and quality of cannabis-based medicines in our health systems.”
The Expert Committee makes decisions on the scheduling of substances based on their potential for harm, dependence and misuse, as well as their medical benefits. The WHO says that it has not reviewed cannabis since it was scheduled in 1961 because there was not sufficient scientific research into the health effects of the drug.
However, the organization said that in recent years this situation has changed, as have attitudes toward the drug. Cannabis and cannabis-related products have now been legalized for medical use in several countries around the world, while Canada, South Africa and Uruguay—as well as several U.S. states—permit its recreational use.
Ethan Russo of the International Cannabis and Cannabinoids Institute told Newsweek that the WHO’s latest proposals were very significant given the organization’s historical stance on cannabis.
“These recommendations are of monumental importance as they may lead to the overcoming of barriers to research, enhance access of patients to cannabis-based medicine, and allow free commerce of cannabis products internationally,” he said.
Meanwhile, international drug policy expert Martin Jelsma from the Transnational Institute said this was the “first time in history” that the WHO had undertaken a proper critical review of cannabis and related substances.
Nevertheless, he said the committee’s proposals don’t go far enough, noting that its rationale for keeping cannabis in Schedule I is “highly questionable.”
“The problem is that after the inclusion of cannabis in 1961 (without a proper WHO review), it became itself one of the standards for further scheduling decisions for Schedule I,” he told Newsweek. “The first test the WHO must do in its review process is whether a substance has ‘addiction-producing properties greater than those of codeine and more or less comparable to those of morphine’ or has ‘a liability to abuse comparable to that of cannabis, cannabis resin or cocaine.’
“Those are the basic criteria for scheduling decisions for Schedule I,” he said. “Now one of the standards itself (cannabis) for the review process is being reviewed, that basic test needs to be done first with regard to similarity with the other standards, e.g., morphine or cocaine. The committee fails to do that which makes the recommendation to keep cannabis and resin in Schedule I very questionable on procedural grounds.”
he U.N. Commission on Narcotic Drugs—which consists of 53 member nations—will decide whether to vote on the new proposals this March or delay the vote till 2020, the BMJ reported.
