Many hemp products line the shelves of Walmart, which are on proud display for shoppers of all ages. Don’t be fooled by the label, though, because the hemp products at Walmart are made from cold-pressed hemp seeds, which contain zero percent CBD.  These hemp products are nutrient-dense and good for your health, but they do not contain any CBD, and thus you should not expect to feel the effects and benefits of CBD when consuming or applying hemp products bought at Walmart.   If you want to know where to buy CBD oil in San Francisco, avoid the Walmart's and CVS’s of the world and stick with a reputable dispensary like Project Cannabis.
