Uncle Herb's now offers its Medicated THC Lip Balm with Natural flavoring infused with 20 mg of THC. You may be wondering why this even exists; instead, think back to when your lips were last chapped. Now imagine applying THC-infused lip balm to those moisture-hungry lips. This stuff disappears pain immediately and provides lips with protection to allow them ample time to recover. High and dry winds never stood a chance.
