Psychedelics Reassessed

A number of psychedelics will be fast-tracked for research into their potential to treat serious mental health issues following an executive order signed by President Donald Trump Saturday.

Many such compounds (including LSD, psilocybin, and more) are classified as Schedule I drugs—illegal to possess and federally regarded as having no medical use. Researchers say the restrictions create significant hurdles for formal clinical trials, despite some evidence they may help treat a range of disorders. 

The order also earmarks $50M for state-level research into ibogaine (pronounced “e-BOW-gain”). The plant-based psychoactive compound is associated with intense episodes and has been linked to cardiac issues but has also proved effective in small studies to alleviate substance use disorders and reduce PTSD symptoms. The order, reportedly prompted by a text message to the president from podcaster Joe Rogan, does not reclassify any of the compounds. 

Listen to veterans discuss their different experiences with psychedelics here.

US Seizes Iranian Ship

The US says it has seized an Iranian ship in the Strait of Hormuz—an almost 900-foot cargo vessel that allegedly refused the US' warnings to stop. The claim comes days before the countries' two-week ceasefire expires Wednesday. See US footage of the ship here.

The US says it has turned away more than 20 ships in the strait, part of its weeklong naval blockade on ships entering or exiting Iranian ports. Control over the strait, through which 20% of the world's oil typically passes, has been a primary sticking point in US-Iran negotiations. Average gas prices in the US may not fall below $3 per gallon again until next year, the US energy secretary has warned. See a live map of ships in the strait here.

Meanwhile, US negotiators head to Islamabad, Pakistan, today to resume peace talks. Iran has not confirmed it will send representatives as of this writing, though reports suggest Iran's delegation will arrive tomorrow.

 

Who Let the Dogs Out?

Hundreds of animal rights activists at a dog-research facility in Wisconsin, including some attempting to break into the facility, were met with rubber bullets and pepper spray Saturday. Dozens of people were arrested.

Ridglan Farms is a beagle-breeding and research lab located 25 miles southwest of Madison. Last year, a special prosecutor found one of the company's experiments likely involved criminal conduct (employees testified dogs had been subjected to surgeries without general anesthesia). The company, which owns roughly 2,000 dogs, has denied wrongdoing but agreed to give up its breeding license July 1. 

In the meantime, a local animal rights group has sought to purchase the dogs for $1M. Last month, the group broke in and removed 22 dogs. Over the weekend, the group again met at Ridglan Farms with avowed plans to break in and release more dogs. One person drove a pickup truck through the front gate, according to police. See footage and interviews with protesters here (via YouTube).
