Marijuana is A Potential Risk to Teen Brains Predisposed to Schizophrenia
Neuroscience News October 25 2023
Summary: Researchers studied the effects of THC, marijuana’s main psychoactive compound, on adolescent mouse brains.
The study found THC-induced structural changes in microglia, specialized brain immune cells, possibly aggravating a genetic predisposition to schizophrenia. The mice treated with THC showed a 33% higher reduction in microglial cells in certain brain regions compared to control mice.
These findings shed light on the potential risks of marijuana use in teenagers, especially those with a genetic susceptibility to psychiatric disorders.

Key Facts:
The study discovered structural changes in the microglia of mouse brains exposed to THC during adolescence, which might worsen a genetic risk for schizophrenia.
Mice with a certain genetic mutation exposed to THC showed a 33% higher reduction in microglia in the brain’s prefrontal cortex compared to normal mice.
The genetically altered mice given THC scored 40% lower on social memory tests than their saline-treated counterparts.

In a mouse study designed to explore the impact of marijuana’s major psychoactive compound, THC, on teenage brains, Johns Hopkins Medicine researchers say they found changes to the structure of microglia, which are specialized brain immune cells, that may worsen a genetic predisposition to schizophrenia.
The findings, published Oct. 25 in Nature Communications, add to growing evidence of risk to brain development in adolescents who smoke or eat marijuana products.

The British Army in Palestine
In the aftermath of the Second World War (1939-45), the British Army found itself stuck in the middle of a growing conflict between Arabs and Jews in Palestine. The momentous events that followed led to the creation of the State of Israel.
Promises
In 1917, in order to win Jewish support for Britain's First World War effort, the British Balfour Declaration promised the establishment of a Jewish national home in Ottoman-controlled Palestine.
However, the British had also promised Arab nationalists that a united Arab country, covering most of the Arab Middle East, would result if the Ottoman Turks were defeated.
When the fighting ended in 1918, with the Ottoman Empire defeated on every front, neither promise was delivered.
Mandate
In 1920, Britain assumed responsibility for Palestine under a League of Nations Mandate. During the next two decades, over 100,000 Jews entered the country.
The British Army's operations in Palestine during this period were mainly directed against militant Arab groups who were opposed to this mass Jewish immigration. Violence reached a height with the Arab Revolt of 1936-39.
Jewish homeland
The Holocaust had a major impact on the situation in Palestine. During the Second World War (1939-45), the British restricted the entry into Palestine of European Jews escaping Nazi persecution. Anxious to appease the Egyptians and oil-rich Saudis, they imposed a limit on Jewish immigration.
This provoked armed Jewish resistance, and eventually united those who looked to Britain for help in establishing their national homeland (the Haganah) and those who wished to use terrorism to drive the British out.
Terrorism
The main terrorist groups were Irgun Zvai Leumi (National Military Organisation) - ultimately led by future Israeli Prime Minister Menachem Begin - and an even more militant organisation, Lohamey Heruth Israel (Fighters for the Freedom of Israel) or LHI.
The British called LHI the Stern Gang after its leader, Abraham Stern, who was killed in a clash with the Palestine Police in 1942. In November 1944, LHI assassinated the British Minister for the Middle East, Lord Moyne.
Refugees
After the Second World War, 250,000 Jewish refugees were stranded in displaced persons camps in Europe. Despite the pressure of world opinion - in particular the repeated requests of US President Harry Truman - the British refused to lift the ban on immigration and admit 100,000 Jews to Palestine.
The Jewish underground forces now united. The Haganah had resisted attacking the British as long as they were fighting Nazi Germany. Now, their fighters allied themselves with Irgun and carried out several raids against the British.
Escalation
In late 1945, in response to full-scale riots in Jerusalem and Tel Aviv, and bomb attacks on the railway system, British troops from the 1st Infantry and 6th Airborne Divisions had to be deployed in support of the civil police.
When the 3rd Infantry Division arrived in Palestine in 1947, the number of British troops deployed there had risen to about 100,000 - the majority of them National Servicemen.
Intelligence failure
Used to conventional fighting in Europe, British troops found it difficult to deal with the violent actions of Irgun and LHI.
The tactics used in the 1930s - curfews, searches and the guarding of key locations - were again put into place. But the Jewish groups enjoyed the support of the local Jewish population and the British found intelligence gathering particularly difficult.

Agatha
Despite this, the High Commissioner Sir Allan Cunningham decided to mount a major blow against the insurgents. On 28 June 1946, 17,000 British troops carried out Operation Agatha in Jerusalem. The Jewish Agency offices and other buildings were raided and arms caches discovered.
A large number of Jews suspected of terrorism were arrested. Anti-terrorist operations were primarily the responsibility of the Palestine Police. The Army's job was to support them, cordoning off villages or sectors of towns, and helping the police search them.
Deadlock
In September 1946, the British called a conference of Jewish and Arab leaders in London. When this ended in deadlock in February 1947, the Government announced it had decided to refer the problem to the United Nations.
Terrorist activity continued, leading to the introduction of martial law and stricter curfews.
Kidnap and bombings
British soldiers were frequently targets for attack and kidnap, often in retaliation for death sentences passed on members of Irgun and LHI. A typical insurgent operation was the bombing of the British Officers Club in Haifa, in which 30 people were killed and injured.
On 22 July 1946, Irgun fighters also blew up a wing of the King David Hotel in Jerusalem, killing over 90 people, including many civilians. This attack broke the fragile Haganah-Irgun partnership.
Ongoing attacks
On 31 March 1947, Irgun set light to the oil refinery at Haifa, starting a fire which blazed for three weeks. In May, it attacked the prison at Acre, freeing a large number of inmates.
On 29 July, in retaliation for the execution of three of their members, LHI kidnapped and hanged two British Army sergeants. They then booby-trapped the bodies so that the officer who cut them down was badly injured.
Withdrawal
In November 1947, the United Nations recommended the partition of Palestine and the establishment of separate Arab and Jewish states.
On 15 May 1948, Britain gave up her mandate. The British Army departed from Palestine leaving the Jews and the Arabs to fight it out in the war that followed. The campaign had cost around 750 British military and police lives.
The clasp ‘Palestine 1945-48’ was added to the General Service Medal and awarded to soldiers who served in Palestine between 27 September 1945 (the date a state of emergency was declared) and 30 June 1948 (when the last British troops departed).

Dear Dr. Freemo: I believe that conspiracies actually exist, someone can contact 2 or more people and conspire to give me a birthday party. They can all agree to sing happy birthday, agree to violate happy birthday song copyright laws. So yes big and small conspiracies do happen, so it is a remote possibility that man never landed on the moon.
Conspiracy is an agreement between two or more people to commit an illegal act, along with an intent to achieve the agreement's goal.
Now the theory that planet earth is flat would be much harder to accept because other planetary bodies seem to be spherical in nature, on planet earth we find naturally occurring nearly round stones. I do have an open mind, I have read most of the flat earth conspiracy theories that claim that world governments are intentionally suppressing the information that the earth is flat.

Dear Dr. Freemo: This is hard for me to say because I do not know the right words to express sorrow. I am just so truly sorry for your personal loss, I just want you to know that I do feel sad, I do deeply care about you.

nostr:npub1kpwlxpzkxfmuxjmzc2wp3rf9vjg0sgydmlhsnrgqr3maf59h86qqdxxzz4 I believe that we need to have a national conversation on restoring U.S.A. economic power; the dog fight between business and labor is non productive. We again need to become innovative, we possess everything we need to succeed, we seem to lack the will to recapture our success after World War II. My opinion is both parties had dropped the ball, let other countries become more technologically savvy than the U.S.. We are now starting to pay for our failure to economically uplift the average citizen. Without the will of the people to be willing to endure hardships and prevail we are a hollow nation of words!

nostr:npub1734e8cvj9tjwt3nrwyvewsgfy4zj8xk0770vf8cv286p4fcj0vvswawlul Yes, unions developed due to a broken system... which is exactly my point.. time to fix the system and cut out the stuff that should have never existed if we did things the right way.
nostr:npub1kpwlxpzkxfmuxjmzc2wp3rf9vjg0sgydmlhsnrgqr3maf59h86qqdxxzz4 Yes but, how will we accomplish this if we cannot build a proper political consensus, we need businesses and labor to work in unison or our country will probably deteriorate into a third world economy. Extreme unregulated capitalism can drag down and eventually destroy our nations similar to that of communism. Major point that I emphasize, is that American Citizens have had it too easy, we have lost our survival skills, we will soon find ourselves creating an underclass of people who no longer have the work ethic. Because the politicians failed to mind the store and big business in the end ultimately sabotaged our economy.

Different laws but more closely related than you may think.
Without anti-trust laws companies could have created coalitions which then could have been used to prevent the worker protection laws from every coming to light. The anti-trust laws are what stop companies from gaining complete control and power and in turn are why we can function to keep them in check at all.
nostr:npub1kpwlxpzkxfmuxjmzc2wp3rf9vjg0sgydmlhsnrgqr3maf59h86qqdxxzz4 Half of what you say is true in a perfect non corrupt world, labor unions sprung into life because businesses in general had a stranglehold on local and state political apparatuses. Labor union organizers had been run out of local municipalities in droves and there had been a lot of blood shed on both sides. We cannot rewrite history to deny what had occurred in violent attempts by businesses to destroy the right workers to engage in peaceful collective bargaining, which in itself is capitalism nor should we attempt to rewrite history and deny that the holocaust ever happened! There are no guarantees that businesses will voluntarily honor anti-trust laws if labor unions cease to exist.

nostr:npub1734e8cvj9tjwt3nrwyvewsgfy4zj8xk0770vf8cv286p4fcj0vvswawlul Of course the laws protect them...if they are enforced... they do nothing when not enforced.... therein lies the problem.

Do not confuse anti-trust laws that are designed to deter monopolies with statutory worker protection laws, they are much distant from each other in functions and intentions; ant-trust laws protect general consumers who are both rich and poor. Statutory worker protection laws mostly are geared to protect blue collar workers and lower level white collar workers.

nostr:npub1734e8cvj9tjwt3nrwyvewsgfy4zj8xk0770vf8cv286p4fcj0vvswawlul I'd argue unions arent needed due to a failure of the USA to "reign in big business"... all that means is we need to start enforcing anti-trust laws. Otherwise we get into the flip side where if unions are allowed than companies are completely justified in what they do as well.

Anti-trust laws really do not protect workers from being exploited by big and small business establishments. Unions came into existence largely due to the failure of local, state, federal government elected and appointed officials to reign in business in general. Anti-trust laws are designed to protect the consumer from unfair market pricing due to monopolies that control the price of goods and services. Reduces rigging of market prices and promotes free trade within a capital system.
Big business continues to hammer away at anti-trust laws, this is not going to stop with the total elimination of labor unions. This is only going to get much worse if unions no longer exist.
Big business will continue to financially exploit workers whether we enforce anti-trust laws or not. Labor union collective bargaining came into existence because big and small businesses work men, women, and children long hours, would not provide basic health and safety on job sites.
Neither businesses nor labor unions are justified in being involved in misconduct; we cannot and should not over rationalize that either businesses or labor unions are the proximate cause of past, present, and future economic failures. Because, say for the sake of argument that businesses and labor unions completely and fully worked together in harmony, U.S.A. still would suffer from natural economic financial crises due to an imbalance in supply and demand of goods and services, which is cycle in nature.

There has always been the danger of unions creating their own massive power structures beyond organized crime. Unions are still needed due to failure by United States Federal Authorities to reign in big business. If we get rid of unions, collective bargaining creases to exist and big business grows even more stronger. U.S. elected politicians have already weakened anti-trust laws, so if we weaken or totally eliminate unions big business will continue lobbying efforts to do away with anti-trust laws and labor unions. There is no easy answer to this problem, U.S. history proves beyond a shadow of a doubt that big business cannot be trusted. U.S. history also proves beyond a shadow of a doubt that organized crime has in the past infiltrated labor unions.
So there has always been dishonestly within U.S. private business on both sides of the equation.
