Birthday Cake Marijuana Strain UK is an THC 20% CBD 1% indica-dominant hybrid with strong body effects and sweet cake-like flavor. As decadent as its Girl Scout Cookies and Cherry Pie parent strains, Birthday Cake buds bloom with a crystalline icing of THC-rich resin. Like any dessert, Birthday Cake is the perfect way to end your day, with deeply relaxing effects that soothe the body without sedating the mind. This strain is preferred by patients treating pain, anxiety, appetite loss, inflammation, and headaches.
