Cannabis oils, vaping devices, packaging materials for vape products and vape products with THC are separately available on Instagram, Amazon and Facebook's Marketplace, the Wall Street Journal reports.

Why it matters: 8 people across the U.S. have died from lung-related illnesses linked to vaping, as of Sept. 20. This online marketplace "is increasingly difficult for law enforcement and tech companies to police because of the geographic distribution of users ... and the use of private accounts and messaging apps to sell illicit products," per the WSJ.

Details: Tech companies say they have policies "against any illegal or inappropriate sales and do remove offenders from their sites," according to the WSJ. They reportedly invest in technology and teams to find "illegitimate products" on their platforms.

  • "... it is illegal to sell THC-containing products online and to ship these across state lines or internationally," the WSJ writes.

What they're saying: “We don’t know what the exact ingredients are on the online, unregulated sources,” University of Miami School of Nursing and Health Studies epidemiologist Denise Vidot, who studies the health effects of cannabis, told the WSJ.

  • “The resources to make it look like you have a legitimate product are easier to get” thanks to the internet, Vlad Valme of Portland, Ore.-based Thompson Duke Industrial, which manufactures vape-pod-filling machines, told the WSJ.

Robert Mueller speaks out on Roger Stone commutation

Former special counsel Robert Mueller responded to claims from President Trump and his allies that Roger Stone was a "victim" in the Justice Department's investigation into Russian interference in the 2016 election, writing in a Washington Post op-ed published Saturday: "He remains a convicted felon, and rightly so."

Why it matters: The rare public comments by Mueller come on the heels of President Trump's move to commute the sentence of his longtime associate, who was sentenced in February to 40 months in prison for crimes stemming from the Russia investigation. The controversial decision brought an abrupt end to the possibility of Stone spending time behind bars.
