I wrote most of the following (there are some updates) in another non-MMJ thread and it was suggested to put a copy here for reference...
I can't use THC, because it activates my mind and keeps me awake, so I convert all my cannabis to CBN. This explains CBN well:
What is CBN...
https://www.leafly.com/news/cannabis-10 ... annabinoidThe oven is too unpredictable for me, so I use UV light for a week, stirring every day, to turn my THC into CBN. I used to make it on a sunny windowsill for a month, but just discovered the UV light, because of the Pacific Northwest winters. Really, any way to turn fresh weed into stale, old weed that no self-respecting stoner would touch, will do the job. (Urban legend is that a stoner found a very old bag of weed and thought why not? And then proceeded to have the best sleep of his life). I got a UV flashlight off Amazon and constructed a dark box out of an Amazon box.
UV BOXcardboard box
aluminum foil
masking tape
UV flashlight (e.g.
http://amzn.to/2pDFycn ...but this one uses a lot of batteries)
batteries
Directions:
1. Remove all cats from the room.
2. Line a cardboard box with aluminum foil (to reflect the UV light).
3. Notch the four flaps that close the box, so when they close, they leave a hole the size of your UV flashlight’s handle.
4. Make aluminum foil trays to hold your cannabis. Size them so you can fit multiple trays on the bottom of your box…but make them large enough that you can spread your cannabis out…then spread your cannabis out. (Label what strain is in each tray. I put a label (with masking tape) on the underside of the tray.)
5. Put aluminum trays in box. Close box so the UV flashlight is inside the box and the handle extends up, from the top. If your flashlight’s handle does not have ridges (and therefore your light would slide down), make ridges from rubber bands. Just wrap rubber bands around the handle until it doesn’t slide down anymore.
6. Turn on flashlight. Check batteries daily. Stir cannabis at least daily. Remove your CBN marijuana in 7 days...vape it, or make an oil tincture, or a cannabutter for an edible like muffins, cookies, brownies.
Here's the recipe I use for my edibles which are gluten free mini muffins, but you can make bars. It doesn't have any caffeine from cocoa/chocolate, or refined sugar, and it's the best of all the recipes I've tried. I'm not even gluten free anymore but I think they taste delicious. For ease of use, you could use any recipe that calls for a stick of butter. I like this one because it has a sticky crumb that stays together so it's easy to cut up into portions, unlike a dry cookie. For determining portions, you might use a scale. I did in the beginning, but found that unlike THC, slight differences in portions of CBN cause no problems. In any recipe, change the oven temperature to no higher than 300 degrees F so you don't cook away the medicinal properties. You'll just need to bake the edible longer than the recipe suggests.
Cannabutter1 stick salted butter (= 1/2 cup)
1/4 ounce (or 7 grams) ground up (herb grinder or scissors) CBN cannabis
Glass container
Crockpot (cheap $15 one on Amazon)
Cheesecloth
Directions: (You might consider making this in your garage, in the backyard, or near an open window due to the strong smell.) Put butter and CBN cannabis in a glass container (mason jar or Pyrex). Put water into the crockpot to make a water bath. Place glass container in water bath (as high as you can go without floating the jar) and cook for 8+ hours, stirring every couple of hours. Then strain through cheesecloth, before it cools, twist and squeeze to get every drop. You can store this Cannabutter indefinitely in the freezer until you are ready to bake.
Options: This Cannabutter recipe was originally for regular THC MMJ and I adapted it for CBN MMJ. It's a good starter recipe using 7 grams of anything, but I've heard of people using larger amounts of MMJ. You can also switch out the butter for oil and Coconut Oil is ideal. Some recipes do call for oil rather than butter. Or your end product can simply be oil. Follow the same directions, then bottle the oil in a colored glass dropper bottle and use as a tincture. I always store all preparations in the refrigerator or freezer.
Gluten Free Coconut Flour Bars or Muffins1/2 cup melted Cannabutter (heat up in oven at 100-125', or on kitchen counter -- but never the microwave)
2/3 cup Honey, Agave Nectar, or Maple Syrup (I use honey)
2 teaspoons Vanilla Extract
4 Eggs, slightly beaten
1/2 cup Milk or Water (I use water)
1 cup Coconut Flour
1 teaspoon Baking Soda
1/2 teaspoon Salt
Butter or Coconut Oil for greasing pan
Ziplock Twist N Loc Storage Containers (protects from crushing)
Directions: Grease your pan (standard 8 x 8 but I use a mini muffin pan) with regular Butter or Coconut Oil. Preheat oven to 300 degrees F. In a large bowl, whisk together Cannabutter, Honey, Vanilla, Eggs, and Water. (I actually warm this mixture into a 110-degree oven, before adding dry ingredients, for a while to ensure the butter stays melted and is evenly distributed.) In a medium bowl, whisk together Coconut Flour, Baking Soda, and Salt. Add dry ingredients to wet ingredients and mix until batter is smooth. Bake until golden brown. (For mini muffins, bake time is 20-22 minutes). Cool and then freeze in Ziploc Twist N Loc containers. Test to find your dosage.
