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.”

UK PM Starmer Says There Could Be New Powers to Ban Pro-Palestinian Marches

British Prime Minister Keir Starmer said the government could ban pro-Palestinian marches in some circumstances because of the “cumulative effect” the demonstrations had on the Jewish community after two Jewish men were stabbed in London on Wednesday.
Starmer told the BBC that he would always defend freedom of expression and peaceful protest, but chants like “Globalize the Intifada” during demonstrations were “completely off limits” and those voicing them should be prosecuted.
Pro-Palestinian marches have become a regular feature in London since the October 2023 attack by Hamas on Israel that triggered the Gaza war. Critics say the demonstrations have generated hostility and become a focus for antisemitism.
Protesters have argued they are exercising their democratic right to spotlight ongoing human rights and political issues related to the situation in Gaza.
Starmer said he was not denying there were “very strong legitimate views about the Middle East, about Gaza,” but many people in the Jewish community had told him they were concerned about the repeat nature of the marches.
Asked if the tougher response should focus on chants and banners, or whether the protests should be stopped altogether, Starmer said: “I think certainly the first, and I think there are instances for the latter.”
“I think it’s time to look across the board at protests and the cumulative effect,” he said, adding that the government needed to look at what further powers it could take.
Britain raised its terrorism threat level to “severe” on Thursday amid mounting security concerns that foreign states were helping fuel violence, including against the Jewish community.
“We are seeing an elevated threat to Jewish and Israeli individuals and institutions in the UK,” the head of counter-terrorism policing, Laurence Taylor, said in a statement, adding that police were also working “against an unpredictable global situation that has consequences closer to home, including physical threats by state-linked actors.”

War Likely to Resume After Trump’s Rejection of Latest Proposal, Says IRGC General

i24 News – A senior Iranian military figure said that fighting with the US was “likely” to resume after President Donald Trump stated he was dissatisfied with Tehran’s latest proposal, regime media reported on Saturday.
The comments of General Mohammad Jafar Asadi, one of the top Islamic Revolutionary Guard Corps (IRGC) commanders, were relayed by the Fars news agency, considered as a mouthpiece of the the powerful paramilitary body.
“Evidence has shown that the Americans do not not adhere to any commitments,” Asadi was quoted as saying.
He further added that Washington’s decision-making was “primarily media-driven aimed first at preventing a drop in oil prices and second at extricating themselves from the mess they have created.”
Iranian armed forces are ready “for any new adventures or foolishness from the Americans,” he said, going to assert that the Iran war would prove for the US a tragedy comparable with what was for Israel the October 7 massacre.
“Just as our martyred Leader said that the Zionist regime will never be the same as before the Al‑Aqsa Storm operation [the name chosen by Hamas leadership for the October 7, 2023 massacre in southern Israel], the United States will also never return to what it was before its attack on Iran,” he said. “The world has understood the true nature of America, and no matter how much malice it shows now, it is no longer the America that many once feared.”

Trump Says US Navy Acting ‘Like Pirates’ to Carry Out Naval Blockade of Iranian Ports

President Donald Trump said on Friday the US Navy was acting “like pirates” in carrying out Washington’s naval blockade of Iranian ports during the US and Israel’s war against Iran.
Trump made the comments while describing the seizure by US forces of a ship a few days ago.
“We took over the ship, we took over the cargo, we took over the oil. It’s a very profitable business,” Trump said in remarks on Friday evening. “We’re like pirates. We’re sort of like pirates but we are not playing games.”
Some of Tehran’s vessels have been seized by the US after leaving Iranian ports, along with sanctioned container ships and Iranian tankers in Asian waters.
Iran has blocked nearly all ships passing through the Strait of Hormuz apart from its own since the start of the war. Trump has imposed a separate blockade of Iranian ports.
The US and Israel attacked Iran on February 28. Iran responded with its own strikes on Israel and Gulf states that host US bases. US-Israeli strikes on Iran and Israeli attacks in Lebanon have killed thousands and displaced millions.
The war has raised oil prices and led to the blockade of the Strait of Hormuz, a chokepoint for about 20 percent of global oil and liquefied natural gas shipments.
Trump, who has offered shifting timelines and goals for the war that remains unpopular in the US, has faced widespread condemnation over his comments on the conflict, including when he threatened to destroy Iran’s entire civilization last month.
Many US experts said last month that American strikes on Iran may amount to war crimes after Trump threatened to target civilian infrastructure.
