True North Weed Co is fully aware of the Vitamin E incidents that are going around in the market, and it’s very sad to see that this is happening. We don’t use any cutting agents or additives to save a couple of dollars. We make sure to fill our carts with Lab Tested premium CO2 extracted distillate. This extra step makes the final product cleaner, smoother and purer. The 510 thread makes it easily compatible with majority of batteries on the market.
