Petrol Wham is said to be perfect for treating conditions such as chronic pain, migraines or headaches, inattentiveness, and depression. Petrol Wham buds have heart-shaped lumpy olive green nugs with amber hairs that are dusted with a thick frosty coating of chunky white crystal trichomes. Petrol has a classic pungent diesel aroma and flavor that’s accented by sharp pineapple and a touch of hashy pine.
