http://www.nma.tv A "Walmart of Weed" has opened in California. However, the store doesn't deal in pot. weGrow sells garden supplies to customers authorized to grow the drug for medicinal uses. weGrow offers in-store training on pot farming techniques and also runs a more stoner-friendly University of Cannabis. Store reps stress: they offer their pot savvy only to people with proven medical needs. Though California's referendum to legalize pot was rejected, pro-pot sentiment remains high. Will stores like weGrow become the next corporate giants?
