Magnitude London Pound Cake - Indica- 1000mg (1g) The London Pound Cake botanically derived terpene cartridge is a light and lemony treat from Magnitude. Its parentage is quite unique, marrying the classic cannabis palate of OG Kush with the vanilla sweetness of Purple Grape to create this tantalizing confection. A session with London Pound Cake will fill your senses with the flavors and aromas of sugary lemons, becoming almost overpowering before it finishes with the rich softness of vanilla cookies.
