Raphael Mechoulam, Israel’s ‘father of cannabis research,’ dies at 92
(JTA) — In the early 1960s, a Bulgarian-born scientist named Raphael Mechoulam was caught carrying five kilograms of, as he called it, “superb, smuggled Lebanese hashish” on a bus from Tel Aviv to Rehovot. But he wasn’t planning on smoking the stuff.
Mechoulam was a fledgling researcher keen on exploring the science behind cannabis, a stigmatized plant whose specific medical properties were not yet known. Over the decades he became a pioneer in cannabis research, whose findings about the psychoactive substance helped ease its entry out of the counterculture and into the mainstream.
Mechoulam died in Israel at age 92; his death was announced Friday by American Friends of the Hebrew University, where Mechoulam helped form The Hebrew University Multidisciplinary Center for Cannabinoid Research in 2017.
“Most of the human and scientific knowledge about cannabis was accumulated thanks to Prof. Mechoulam,” Hebrew University President Asher Cohen said in a statement. “He paved the way for groundbreaking studies and initiated scientific cooperation between researchers around the world. Mechoulam was a sharp-minded and charismatic pioneer.”
As a professor in the Hebrew University School of Pharmacy, Mechoulam and his research team isolated THC, the psychoactive component of cannabis, as well as cannabidiol, or CBD, an active ingredient in cannabis with a range of medicinal benefits.
He also pioneered the study of the body’s own cannabinoid system, which produces chemicals similar to THC to help regulate appetite, manage pain and operate the immune system.
As Mechoulam discovered more about cannabis and its efficacy in easing symptoms of cancer, epilepsy and other diseases, he lamented that strict drug laws in the United States and elsewhere suppressed research and kept the derivatives of cannabis off the market.
“Medicinal cannabis has to follow medical lines of thought and development and modern medical routes” in order to be part of proper drugs, he told the New York Times in 2017. “Israel has more [clinical trials] than the United States at the moment, which is ridiculous.”
Mechoulam was a founding member of the International Association for Cannabinoid Medicines and the International Cannabinoid Research Society. In 1994, he was elected to be a member of the Israel Academy of Sciences and Humanities.
Mechoulam was born in Bulgaria in 1930 and immigrated in 1949 with his family to Israel, where he later studied chemistry. He received his PhD at the Weizmann Institute in Rehovot, writing a thesis on the chemistry of steroids. After postdoctoral studies at the Rockefeller Institute in New York, he joined the scientific staff of the Weizmann Institute.
Mechoulam became a full professor at Hebrew University in 1972 and was named the Lionel Jacobson Professor of Medicinal Chemistry in 1975, serving as the university’s rector from 1979-1982.
In 2022, the YIVO Institute for Jewish Research in New York City mounted its exhibition on Jewish contributions to the history of cannabis and highlighted the work of Mechoulam. “He’s worked on cannabis his entire life, and in the 1990s he and his colleagues discovered the endocannabinoid system, which regulates homeostasis — a significant discovery on how the human body deals with cannabinoids,” Eddy Portnoy, who curated the exhibit, told the Jewish Telegraphic Agency at the time. “I read an interview with him where he says that because he was in a small country, he would have to find a niche that other people weren’t working in.”

Some Tankers Cross Strait of Hormuz Before Shots Fired, Ship-Tracking Data Shows

More than a dozen tankers, including three sanctioned vessels, passed through the Strait of Hormuz after a 50-day blockade was lifted on Friday, shipping data showed, before Iran reimposed restrictions on Saturday and fired at some vessels.
Reopening the strait is key for Gulf producers to resume full oil and gas supplies to the world, and end what the International Energy Agency has called the worst-ever supply disruption.
US President Donald Trump said on Friday Iran had agreed to open the strait, while Iranian officials said they wanted the US to fully lift its blockade of Iranian tankers.
Western shipping companies cautiously welcomed the announcements but said more clarity was needed, including on the presence of sea mines, before their vessels could transit.
IRAN RESUMES RESTRICTIONS
The ships that passed through the strait on Friday and Saturday via Iranian waters south of Larak island were mainly older, non-Western-owned vessels and included four sanctioned ships, according to ship-tracking data.
Iran arranged passage for a limited number of oil tankers and commercial ships following prior agreements in negotiations, a spokesperson for Iran’s Revolutionary Guards said.
Other ships have been seen approaching the strait and turning back as Iran said it would maintain strict controls as long as the US continues its blockade of Iranian ports.
The UK Navy reported on Saturday that Iranian gunboats fired at some ships attempting to cross the strait.
Some merchant vessels received radio messages from Iran’s navy saying the strait was shut again and that no ships were allowed to pass, shipping sources said on Saturday.
Ship-tracking data showed five vessels loaded with liquefied natural gas from Ras Laffan in Qatar approaching the strait on Saturday morning.
No LNG cargoes have transited the waterway since the US-Israeli war with Iran began on February 28.
Hundreds of ships have been stuck in the Gulf since the conflict started and Tehran closed the strait, forcing Gulf oil and gas producers to sharply cut production.
Top producers such as Saudi Arabia, the UAE, Iraq and Kuwait say they need steady tanker flows and unrestricted passage through the strait to resume normal export operations.

Trump Greenlights Russian Oil to Ease Strain on Global Markets After War with Iran

i24 News – The Trump administration has authorized a 30-day emergency waiver allowing the maritime purchase of Russian oil, reversing a hardline stance in an effort to stabilize skyrocketing global energy prices.
The Treasury Department announced Friday that the license for crude and petroleum products will remain in effect until May 16, 2026, responding to intense pressure from international partners struggling with the fallout of the war with Iran.
This policy pivot comes as a surprise after Treasury Secretary Scott Bessent suggested earlier this week that no further exemptions would be granted:
“As negotiations with Iran accelerate, the administration seeks to ensure oil availability for those who need it most. We must prevent a total price collapse for consumers while the geopolitical situation remains volatile.”
Ensuring global oil availability is paramount for the US as over 80 energy facilities in the Middle East have been damaged by recent war with Iran. With the November midterm elections approaching, record-high fuel prices at the pump remain a primary vulnerability for the Republican party. By allowing Russian oil back into the maritime flow, the administration hopes to neutralize “pain at the pump” before voters head to the polls.

UK: Islamist Group Claims to Attack Israeli Embassy with ‘Drones Carrying Radioactive, Carcinogenic Materials’

i24 News – British police officers in protective clothing were seen investigating a “security incident” near the Israeli embassy in London on Friday, after a jihadist group put out a video showing it launching two drones allegedly carrying radioactive and carcinogenic materials toward the embassy.
“There is an increased police presence in Kensington Gardens and officers are assessing a number of discarded items. As a precaution, some of the officers who have been deployed are wearing protective clothing. We recognize this may concern local residents and the wider public,” police said in a statement.
“Counter Terrorism Policing London are aware of a video shared online overnight in which a group claims to have targeted the nearby embassy of Israel with drones carrying dangerous substances,” the statement further read. “While we can confirm that the embassy has not been attacked, we are carrying out urgent inquiries to determine the authenticity of the video and to identify any potential link between it and the items discarded in Kensington Gardens.”
The incident comes amid a steep hike in antisemitic attacks in Britain targeting Jewish and Israeli individuals and institutions.
The group that released the video was identified as Harakat Ashab al-Yamin al-Islamia, a shadowy entity with suspected ties to Iran. It has already claimed seven attacks against Jewish institutions, including an arson attack in London where four ambulances owned by the Hatzolah charity were torched.
