Experiencing the pre rolled with kief ?s legendary taste and power should be on any serious cannabis connoisseur?s bucket list. pre rolled with kief was created decades ago by combining all-but extinct heirloom varieties from Thailand, Colombia, Mexico and Afghanistan. The result is a vigorous hybrid with a heavy, raw terpene profile. pre rolled with kief makes extremely strong extracts with a very high amount of noticeable terpenes. Users who have made rosins, or wax, from this plant report it as being the strongest extract that they have ever had.
