The Vibin Premium Delta 10 THC tincture by Effex is second to none! Sour Blueberry OG is a mix between Sour Diesel and blueberry, making this a go-to hybrid blend for many. The flavor alone keeps users coming back for more, and for good reason. Who wouldn't love the taste of sour blueberries? Because this is a hybrid blend, the effects are multifaceted, offering a slightly stoning body high coupled with an invigorating cerebral head high.
