What is the difference between kief and RSO?
Kief is the loose, powdery resin glands sifted off dried flower; you sprinkle it onto a bowl or into a joint to raise the strength. RSO (Rick Simpson Oil) is a thick, dark, full-spectrum extract that is swallowed in tiny amounts or added to food, not smoked. Both are far stronger by weight than flower, so measure carefully.

Sprinkle a small pinch over ground flower in a bowl or roll it into a joint, where it melts into the burn. A little goes a long way; a gram of kief at around 40% THC is roughly twice the strength of the same weight of flower. Keep it in the jar it came in and use a small spoon or the lid to portion.
Squeeze a rice-grain-sized amount from the syringe onto a cracker or into food, or place it under the tongue. At around 75% THC, a grain that size is already several milligrams. Treat it like an edible: start very small, wait at least two hours, and never vaporize or dab it, since it contains plant material that does not heat cleanly.
No. Kief goes into a bowl or joint and RSO is taken by mouth. Dab rigs and concentrate vaporizers are for textures such as live resin, rosin, badder, and shatter, which are not part of this collection today.
Flower on the menu tests between roughly 18% and 34% THC; the kief here tests around 40% and the RSO around 77%. Because the percentage is by weight, a small amount of concentrate carries the THC of a much larger amount of flower, which is why the whole collection sits under the Extra Strength filter.
RSO is sold here as an adult-use product and makes no medical claims. It became known through home-extraction recipes, but the RSO on a licensed menu is lab tested and labeled for THC like any other product. It is popular with people who want a strong, long-lasting oral dose without smoking.
Both keep best sealed, cool, and dark. Kief clumps in heat and humidity, so a small glass jar in a cupboard is ideal; RSO can be refrigerated to stay firm, then warmed in your hand for a minute so it dispenses cleanly from the syringe.
