Moldy weed is characterized by a grayish-white powdery or fuzzy coating, along with black or dark green splotches. Bud rot, a type of mold, causes cannabis buds to decay from the inside out, leading to dark, discolored, or mushy buds.

Recognizing moldy weed is crucial for ensuring the safety of cannabis consumption. Visual cues such as discoloration, fuzzy texture, and a musty odor are indicative of mold presence. It’s essential to distinguish between mold and trichomes, the resinous glands that contain cannabinoids and give cannabis its potency.
