Bubble hash, also known as ice water hash, is a popular solventless cannabis concentrate made by separating resin-rich trichomes from the cannabis plant using ice, water, and agitation. The aroma will bring on a earthy and herbal overtone accented by nutty peanut butter and sweet citrus hints. The Electric PB Cookies high will begin a few moments after your final exhale, starting with a mild cerebral spark that quickly grows into a smooth, sweet sense of calm.
