If this column comes across as fuzzy-minded, please cut me some slack. Perhaps we can blame THC, the chief mind-altering substance in marijuana. Though possession of small amounts of weed wonât be legal in Virginia (for adults age 21 and up) until July 1, THC-infused gummies and vape cartridges already are being sold in smoke shops and CBD boutiques around the Roanoke Valley. Some even sell THC brownies. You can find the products along Brambleton Avenue in Roanoke County, or on Main Street in Roanokeâs Wasena neighborhood, and occasionally at convenience stores in other locations. Theyâre pretty cheap, too. I recently bought a pack of 20 for $40.
