PROBLEM: [header] How to make marijuana tea [title] Grind the marijuana buds. [step] Separate out the stems and seeds if necessary, and use a grinder or chop up the buds with a sharp knife until they're finely chopped, but not completely powdered. [title] Mix the buds with butter. <sep> (A) [step] Place them together in a bowl and use a spoon to mix up the buds and butter, making sure each piece is coated with fat. You want the grounds to be completely coated, but not soaked in butter; too much will inhibit the release of thc. (B) [step] Combine two tablespoons (59.6 ml) of butter with 1 teaspoon (4 g) of ground black pepper. Spread this mixture over the marijuana buds, and let it sit for several minutes. (C) [step] Pour the liquid ingredients from the grinder into a blender or food processor, then pulse the contents until well mixed. [title] Punch holes in the buds with a fork. (D) [step] Pour the softened butter into the potting mix. Press the buds down with your finger to blend them together without flaking off.

PROBLEM: [header] How to deactivate your cat [title] Use this only when necessary. [step] In one study, thirty out of thirty-one cats reacted positively, and none showed signs of pain or fear. Still, your cat may not enjoy it. <sep> (A) [substeps] Read product descriptions to learn how to safely deactivate your cat. Once they have deactivated, they are less likely to be inclined to do it again. (B) For this reason, you will want to give your cat the option of deactivation before extending any line of treatment. If your cat shows no reaction, and no whimpering, do not use this. (C) Some cats're immune to using this solution, though. Think about this: if your cat has not responded to any of the other methods, there is a good chance they like this variation. (D) Many vet technicians consider " scruffing " techniques old-fashioned, and too intense for regular use. Some say this technique is a more gentle option, but this is controversial.
