Marijuana Smokers Prone To Head, Neck Cancers — Study

New research suggests a strong link between long-term daily marijuana use and head and neck cancers.

A recent study analyzing millions of medical records found that individuals with cannabis use disorder—characterized by symptoms such as cravings, tolerance, and withdrawal—are three to five times more likely to develop these cancers compared to non-users.

Cannabis use disorder is diagnosed when a person exhibits two or more symptoms as defined by the US Centers for Disease Control and Prevention, including intense cravings, reduced effects over time, excessive use, continued use despite negative consequences, and difficulty quitting.

According to Dr Niels Kokot, a professor of clinical otolaryngology-head and neck surgery at the Keck School of Medicine at the University of Southern California in Los Angeles, research shows that people who use cannabis, particularly those with a cannabis use disorder, are significantly more likely to develop head and neck cancers compared to those who do not use cannabis. “While our study did not differentiate between methods of cannabis consumption, cannabis is most commonly consumed by smoking, The association we found likely pertains mainly to smoked cannabis.”

Some 69 percent of people with a diagnosis of oral or throat cancer will survive five years or longer after their diagnosis, according to the National Cancer Institute. If the cancer metastasizes, however, that rate drops to 14 percent. About 61 percent of people diagnosed with cancer of the larynx will be alive five years later – a rate that drops to 16 percent if the cancer spreads.

The study used insurance data to look at the association of cannabis use disorder with head and neck cancers, said Dr. Joseph Califano, the Iris and Matthew Strauss Chancellor’s Endowed Chair in Head and Neck Surgery at the University of California, San Diego. “The researchers used a huge, huge dataset, which is really extraordinary, and there is enormous power in looking at numbers this large when we typically only see small studies,” said Califano, also the director of University of Californ8a, San Diego’s Hanna and Mark Gleiberman Head and Neck Cancer Center.

“On average, people with cannabis use disorder smoke about a joint a day and do so for at least a couple years, if not longer,” said Califano, who coauthored an editorial published in JAMA Otolaryngology-Head & Neck Surgery in conjunction with the new study.

However, he added, the study does not find an association between “the occasional recreational use of marijuana and head and neck cancer.”

20 Members Of Gang Blacklisted By US Escape Guatemala Prison

Twenty members of a gang designated a “foreign terrorist organisation” by the United States have escaped from detention in Guatemala, a prison chief said Sunday.

The members of the Barrio 18 gang “evaded security controls” at the Fraijanes II facility, prison director Ludin Godinez said at a news conference.

He received “an intelligence report” on Friday warning about the “possible escape” from the prison, which is southeast of the capital, Guatemala City.

Godinez said they were investigating possible acts of corruption.

Washington last month blacklisted Barrio 18, an El Salvador-based gang which has a reputation for violence and extortion, as part of its crackdown on drug trafficking.

The US embassy in Guatemala condemned the prison escape as “utterly unacceptable.”

“The United States designated members of this heinous group as the terrorists they are and will hold accountable anyone who has provided, provides, or decides to provide material support to these fugitives or other gang members,” the embassy said on X.

It called on the Guatemalan government to “act immediately and vigorously to recapture these terrorists.”

According to Interior Minister Francisco Jimenez, there are about 12,000 gang members and collaborators in Guatemala, while another 3,000 are in prison.

The country’s homicide rate has increased from 16.1 per 100,000 inhabitants in 2024 to 17.65 this year, more than double the world average, according to the Centre for National Economic Research.

According to the Salvadoran government, the gangs Barrio 18 and Mara Salvatrucha, better known as MS-13, are responsible for the deaths of about 200,000 people over three decades.

The two gangs once controlled an estimated 80 percent of El Salvador, which had one of the highest homicide rates in the world.

South Africa Bus Crash Kills 40 Including Malawi, Zimbabwe Nationals

At least 40 people, including nationals of Malawi and Zimbabwe, were killed when a passenger bus rolled down an embankment in South Africa, a provincial transport minister said Monday.

The bus travelling to Zimbabwe crashed around 90 kilometres (55 miles) from the border on Sunday after the driver apparently lost control, Limpopo province transport minister Violet Mathye said.

“They are still working on the scene, but 40 bodies have already been confirmed to date,” Mathye told the Newzroom Afrika channel. The dead included a 10-month-old girl, she said.

Thirty-eight people were in hospital and rescuers were searching for other victims, she told eNCA media.

The bus was travelling from the southern city of Gqeberha, around 1,500 kilometres away, and its passengers included Malawians and Zimbabweans who were working in South Africa. The crash may have been caused by driver fatigue or a mechanical fault, the minister said.

South Africa has a sophisticated and busy road network with a high rate of road deaths, blamed mostly on speeding, reckless driving and unroadworthy vehicles.
