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.”

Israel Says It Kills Senior Hamas Commander Raed Saed in Gaza

The Israeli military said it killed senior Hamas commander Raed Saed, one of the architects of the October 7, 2023 attacks on Israel, in a strike on a car in Gaza City on Saturday.

It was the highest-profile assassination of a senior Hamas figure since a Gaza ceasefire deal came into effect in October.

In a joint statement, Israeli Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz said Saed was targeted in response to an attack by Hamas in which an explosive device injured two soldiers earlier on Saturday.

The attack on the car in Gaza City killed five people and wounded at least 25 others, according to Gaza health authorities. There was no immediate confirmation from Hamas or medics that Saed was among the dead.

HAMAS SAYS ATTACK VIOLATES CEASEFIRE AGREEMENT

An Israeli military official described Saed as a high-ranked Hamas member who helped establish and advance the group’s weapons production network.

“In recent months, he operated to reestablish Hamas’ capabilities and weapons manufacturing, a blatant violation of the ceasefire,” the official said.

Hamas sources have also described him as the second-in-command of the group’s armed wing, after Izz eldeen Al-Hadad.

Saed used to head Hamas’ Gaza City battalion, one of the group’s largest and best-equipped, those sources said.

Hamas, in a statement, condemned the attack as a violation of the ceasefire agreement but did not say whether Saed was hurt and stopped short of threatening retaliation.

The October 10 ceasefire has enabled hundreds of thousands of Palestinians to return to Gaza City’s ruins. Israel has pulled troops back from city positions, and aid flows have increased.

Hezbollah Chief: Disarmament Would Be ‘Death Sentence’ for Lebanon

i24 NewsHezbollah leader Naim Qassem said on Saturday that it was not the responsibility of the Shiite terror group “to prevent aggression,” but rather the Lebanese state’s, and it is the responsibility of Hezbollah to engage “when the state and army fail to do so.”

In a recorded televised statement, Qassem sarcastically posed the question whether it was not Hezbollah that should be demanding the Lebanese Army’s disarmament if the latter fails to stop “Israel’s ongoing aggression.”

On the issue of disarming Hezbollah, Qassem said that disarming it in the manner currently proposed is a death sentence for Lebanon.

“Even if the sky falls, we will not be disarmed, not even if the entire world unites against Lebanon. We will not allow this and it will not happen,” Qassem said.

High schoolers’ ‘human swastika’ on football field shakes San Jose Jewish community

(JTA) — The photo spread swiftly after a student posted it on social media: Eight California high schoolers were lying on their school’s football field, their bodies arrayed in the shape of a swastika.

Alongside the picture was a quote from Adolf Hitler, threatening the “annihilation of the Jewish race.”

The incident at Branham High School in San Jose began on Dec. 3 and has roiled the local Jewish community in the days since, as the wrenching saga has ignited suspensions, recriminations and alarm from around the world.

The photograph and the response to it were first reported by J. Jewish News of Northern California.

“We don’t want to see hatred,” Cormac Nolan, a Jewish Branham senior, told the local Jewish newspaper. “We don’t want to see the idolization of one of the most evil men to ever walk the face of the Earth. We don’t want someone who spews out hatred like this on our campus.”

The school’s student newspaper reported that the students involved had been suspended, and that dozens of other students walked out to protest the incident.

The San Jose Police Department told J. that it is investigating the incident, and the school’s principal, Beth Silbergeld, who is Jewish, said the school was working with the Anti-Defamation League and the Bay Area Jewish Coalition, a local antisemitism advocacy group, “to ensure that we receive appropriate support and guidance as we work to repair the harm that’s been done to our community.”

Silbergeld told J. that she felt pressure to learn from the incident.

“I’ve been in education for a long time and have seen, sadly, lots of incidences of oppression and hate toward many groups,” she said. “I think that we always have a responsibility as schools to do what’s right and to take action and learn from the experiences of other other schools and other incidents as a way to hopefully eliminate actions like what we’ve experienced.”

The incident is not the first time Branham High School has faced controversy over antisemitism on its campus. In April, the California Department of Education ruled that the school had discriminated against its Jewish students by presenting “biased” content about the Israeli-Palestinian conflict in a 12th-grade ethnic literature curriculum.

It is also not the first instance of a “human swastika” roiling a school community. In 2019, nine middle schoolers in Ojai, California, also arranged themselves in a “human swastika” and faced disciplinary measures from the school.

Exactly what possessed the Branham students to do what they did is not clear. But psychologists told the J. that the teen years are a peak moment for transgressive behaviors that may or may not reflect deep-seated biases.

“It’s a developmental time where you’re doing new things, you’re trying new things, you’re making mistakes, you’re trying to fit in, you’re trying to get laughs and likes,” Ellie Pelc, director of clinical services at the Bay Area’s Jewish Family and Children’s Services, told the newspaper. “And you often do so in some hurtful or harmful ways that you don’t always have the capacity to think through in advance.”

The photo was met by condemnation by California State Sens. Scott Wiener, who wrote that antisemitism was “pervasive & growing” in a post on Facebook, and Dave Cortese, who said he was “deeply disturbed” by the incident in a statement.

“What happened at Branham High School was not a joke, not a prank, and not self-expression — it was an act of hatred,” wrote San Jose Mayor Matt Mahan in a post on X. “The fact that this was planned and posted publicly makes it even more disturbing.”

By Tuesday, the uproar had sparked a response from district leaders. In a post on Facebook, Robert Bravo, the superintendent for the Campbell Union High School District, wrote that the district “will respond firmly, thoughtfully, and within the full scope allowed by Board Policy and California law.” (Displaying a Nazi swastika on the property of a school is illegal in California.)

He added that the school district considered the incident an instance of “hate violence” based on California state education code, which allows for suspension or expulsion in such cases.

“Our response cannot be limited to discipline alone,” continued Bravo. “We are committed to using this incident as an opportunity to deepen education around antisemitism, hate symbols and the historical atrocities associated with them.”

The antisemitic post comes two months after California Gov. Gavin Newsom signed a bill creating a statewide office assigned to combatting antisemitism in California public schools. The office, which is the first of its kind in the country, was met with praise from local Jewish advocacy groups while some critics warned it could chill academic freedoms.

Marc Levine, the regional director of the Anti-Defamation League in the Central Pacific region, called the incident “repulsive and unacceptable” in a statement on X. The incident was also condemned by the Jewish Community Relations Council of the Bay Area, which wrote in a statement that it had been working with the school about “how to ensure an effective response.”

The Bay Area Jewish Coalition also issued a statement on Tuesday, writing that the antisemitic act had “shaken Jewish families across Northern California and beyond.”

“We hope that what happened at Branham serves as a wake-up call for California and for the rest of the country to take the antisemitism crisis seriously and reverse the trend through real, meaningful action and long-term change,” the statement continued.
