Marijuana moonrocks first appeared in the late 2000s, after West Coast rapper Kurupt developed his variety “Kurupt Moonrocks” in conjunction with music artist Dr. Zodiak. Making moon rocks involves dipping high-grade marijuana buds in concentrated cannabis oil, then rolling them in or sprinkling kief on them. This process results in a highly potent combination that packs a powerful punch. Moon rocks are for experienced smokers seeking to get the most out of their weed. Recent advances in extraction methods enabled marijuana experts to make even more concentrated forms of moon rocks that boast higher THC levels. Some people use the terms cannabis caviar and moon rocks interchangeably. However, the original descriptions refer to two different products. Cannabis caviar can be moon rocks or simply nugs coated with cannabis oil. If your budtender mentions caviar as you shop for moon rocks, confirm whether they are talking about the kief-covered moon rocks.
