What's the difference between Delta 8 THC and marijuana or 'weed'?
Hoosiers might have started to notice gummy products labeled "Delta 8" or even "THC" in their corner stores or vape shops over the last few years.
In the state legislature, lawmakers have been tinkering for years with bills to try to regulate these off-brand cannabis products that the federal government accidentally legalized.
The difference between Delta 8 and the kind of marijuana we colloquially call "weed" or "pot" comes down to some chemistry and an arbitrary federal definition.
They all come from the same plant, Cannabis sativa. This plant contains hundreds of chemical substances known as cannabanoids.
Tetrahydrocannabinol, or THC, is the psychoactive cannabanoid responsible for the "high" associated with marijuana. This is also called Delta 9 THC.
Delta 8 THC is another cannabanoid in the plant. It's an isomer, or a slightly altered chemical compound related to Delta 9 THC, but less psychoactive.
However, since there isn't a lot of naturally occurring Delta 8, most Delta 8 on the market is made in a lab and is derived from what the federal government now considers "hemp." That's where the federal definitions come in.
In the 2018 Farm Bill, Congress wanted to give farmers a legal way to make agricultural textiles from less potent varieties of the cannabis plant, or hemp.
Lawmakers decided to codify a dividing line between legal hemp and illegal marijuana. Hemp would henceforth be known as dry cannabis flower with less than 0.3% concentration of Delta 9 THC, and marijuana, illegal on the federal level, is flower with higher concentrations.
Cannabis cheat code: Marijuana is illegal in Indiana, but this loophole makes it complicated
The Farm Bill didn't address isomers like Delta 8. So the market has innovated all kinds of products and derivatives from plants containing less than 0.3% Delta 9 ― or legal hemp ― including Delta 8, THCa and all kinds of other letters and numbers.
This is the impact of the loophole: It's possible to sell products containing very high concentrations of Delta 8, enough to mimic intense psychoactive effects, and still abide by that federal definition. THCa, which can also be found in Indiana stores, is another example: when dry, it abides by the legal definition, but when exposed to heat, it chemically transforms into regular Delta 9 THC.
A bill to regulate Delta 8 and other hemp-derived THC products died on the last day of the Indiana legislative session.
Meanwhile, the cannabis industry is lobbying Congress heavily to pass an amendment that would close the loophole the Farm Bill created.
For now, there remain no regulations on these products.

New Report Highlights Air Traffic Control Staffing Woes
A new report released on Wednesday highlighted the Federal Aviation Administration's struggles to address critical staffing shortages among air traffic controllers and called on Congress to help the agency reverse the trend. The report by a nonprofit that does research for Congress faulted some towers for inefficient practices. But it also pointed to external obstacles, including government shutdowns and the COVID-19 pandemic, that compounded the F.A.A.'s difficulty in keeping control towers staffed overall. The shortages have contributed to near-misses and other accidents that, combined with outmoded and problematic technology, have heightened concerns about the safety of air travel. 'Scanning the horizon, it's become clear that the U.S. needs to make a few important course corrections to ensure that F.A.A.'s facilities are adequately staffed, helping keep our skies safe for decades to come,' William J. Strickland, the chair of the committee that wrote the 250-page report, said in a statement accompanying its release. Mr. Strickland is the former head of the Human Resources Research Organization, which provides staffing assessments for companies and the government. The report from the Transportation Research Board of the National Academies of Sciences, Engineering and Medicine, a nonprofit authorized by Congress to provide advice to the federal government on matters of science and technology, was ordered by lawmakers as part of legislation authorizing the F.A.A. to embark on new key ventures. Those include accelerating the hiring of air traffic controllers and investments in advancements in aviation infrastructure and advanced technology. It was published at a moment of heightened scrutiny of aviation safety and the air traffic control system in particular, following a deadly Jan. 29 crash at Ronald Reagan National Airport. Since then, there has been a series of near-misses and outages, including multiple failures at Newark International Airport, where staffing at the facilities monitoring air traffic remains alarmingly low.

What is Juneteenth? The meaning behind the June 19 federal holiday
June 19 marks Juneteenth, a holiday that commemorates the emancipation of enslaved people in the United States. It became a federal holiday in 2021 when then-President Joe Biden signed the Juneteenth National Independence Day Act into law. Now, across the country, many people have off from work and use Juneteenth to celebrate, reflect and educate themselves on the dark history of slavery in the U.S. Juneteenth commemorates June 19, 1865. That was when Union General Gordon Granger arrived in Galveston, Texas, and announced that over 250,000 enslaved people were free, more than two years after the Emancipation Proclamation was issued by President Abraham Lincoln and declared slaves in Confederate states were free. Originally celebrated by newly freed Black communities in Texas with religious services, barbecues and symbolic traditions like discarding clothing worn during enslavement, the holiday has since grown beyond Texas and the South. Though festivities resurfaced in Black communities during the 1960s Civil Rights Movement as a way to honor their legacy, the holiday — sometimes referred to by other names such as 'Second Independence Day,' 'Freedom Day,' 'Emancipation Day' or 'Black Fourth of July' — gained national attention once again during the 2020 Black Lives Matter movement. The movement inspired Congress and Biden to create an official federal holiday to honor Juneteenth the following year. Modern Juneteenth festivities are vibrant and celebratory, and typically involve outdoor activities like cookouts and picnics. Large community events are also held: Last year, the White House hosted a concert on the South Lawn for Juneteenth and Black Music Month. This year, Juneteenth events across the country include things like film screenings, festivals, concerts and other community cultural events. In an opinion piece for the Arizona Republic, Greg Moore wrote, 'It's a good time to find a community of people and celebrate the racial progress we've made over the last few decades…And given all the separation Black Americans have faced through history, it would be fitting to celebrate in a community gathering — the bigger, the better.' Some people may prefer to use Juneteenth as a day of reflection, education and remembrance. That could include going to a museum, some of which are hosting special programs for the holiday on Black American history. The National Civil Rights Museum in Memphis, Tenn., is marking Juneteenth with free admission and educational activities for families. This year, many Juneteenth events have been scaled back or canceled because companies and local governments are cutting funding for diversity, equity and inclusion (DEI) initiatives. You can honor Juneteenth even if you are not Black, Karida Brown, a sociology professor at Emory University, told the Associated Press. Brown explained that the history of slavery in America is all of our history, and it's important to recognize 'the good, the bad, the ugly, the story of emancipation and freedom for your Black brothers and sisters under the Constitution of the law.' However, Moore wrote in the Arizona Republic that it's important not to let Juneteenth go the way of holidays like Cinco de Mayo, in which cultures are reduced to harmful stereotypes. He's afraid Black culture can be 'warped beyond recognition' during disrespectful celebrations. 'There shouldn't be any blackface or watermelon jokes,' he said. While red, green and black are colors associated with Juneteenth — those are the colors of the pan-African flag, which represents the African diaspora and the unity of Black people — the Juneteenth flag is red, white and blue. It was created in 1997 by community organizer and activist Ben 'Boston Ben' Haith in order to give the holiday a unifying symbol. 'For so long, our ancestors weren't considered citizens of this country,' Haith said in an interview with Capital B. 'But realistically, and technically, they were citizens. They just were deprived of being recognized as citizens. So I thought it was important that the colors portray red, white, and blue, which we see in the American flag.' The star in the center stands for two things: Texas, where Juneteenth began, and, according to Haith, the white burst around the star symbolizes a new star being born — representing a new beginning for Black Americans. The red arc below it represents a horizon, signifying progress and hope for the future. While Juneteenth is now a federal holiday, people employed in the private sector are not legally required to recognize or observe the holiday. In turn, privately owned shops, restaurants, grocery stores and other retail businesses will likely keep normal hours on the holiday unless they choose to honor the holiday in some way. Most major banks, as well as the stock market, are closed on Juneteenth. So is the post office and other federal offices. Public schools and libraries are typically closed as well.
