Pack contains 10 x 0.7 gram joints or "dog walkers" infused with Delta-9 THC distillate. One of the most common infused pre-rolls is made with a THC distillate. Distillation is a way to ensure the THC is as pure as it can be. Distillate-infused pre-rolls are great if you're on a budget — you get pure and potent THC that packs a punch.
