KRTV # 10 p.m. on KREM With much of the rest of the planet still dealing with a new variant of the coronavirus, the novelty of a group of strangers in a house cut off from the “outside world” may have resonated a bit differently for viewers, but Season 23 of this reality competition series continued to play out as usual, with its pool of 16 Houseguests reduced each week by eliminations. In tonight’s twohour finale, a jury of previously ousted players decides which of two finalists deserves the $750,000 grand prize. Julie Chen Moonves hosts.

KSPS An estimated 55 million Americans say they use cannabis, and that number is expected to grow as voters in more and more states push for legalization. The new episode “The Cannabis Question” explores our relationship with cannabis, uncovering what scientists have discovered about the plant’s effects on the body and brain. Though many believe cannabis is benign, even beneficial, confusion reigns as the federal government still classifies it as a Schedule 1 drug, in the same category as heroin.
