THC Oil Bubble

I will be describing a step by step guide, in detail, a technique of extracting the cannabanoids from your Nugs and/or trim and turn it into medical grade Hash Oil. The final product will be a dark, oily liquid that contains 70%-100% pure THC. The following steps require nothing more than simple, easy to find materials as well as a little time and caution.

 

Advantages of THC oil:
• No hot, harsh smoke to irritate your lungs
• No tar to stain your teeth and fingers
• Minimal amount of smell
• 5 times as much THC in bloodstream, meaning less inhalations
• No carcinogens to give you cancer

 

Materials you'll need for extraction:
• A glass jar with a watertight lid (widemouth Mason jars work great)
• A metal measuring cup with handle (2 cup capacity recommended)
• Bottle of 190 proof grain alcohol (Everclear brand is perfect)
• Any quantity of marijuana, any strength (from a gram up to a few ounces)
• A 1' X 1' piece of sturdy cloth (t-shirt material works fine)
• An eye-dropper bottle (contact lens type bottles work great)
• The use of an ELECTRIC stove and an overhead fan

 

Step 1
You'll need to grind your marijuana and pick apart the Nug’s until it looks like grass clippings. Remove any seeds.  Dump the powdered nugs into the mason jar and pour in just enough grain alcohol so the weed particles float freely in the mixture. Place the lid securely on the jar and shake a few times.

 

Let this mixture sit for a few hours, shaking it every 45 minutes.  The alcohol should turn a dark green color and, when shaken, should form colorful and oily bubbles on top.

 

Place the sturdy cloth over the metal container and press the cloth down to form a funnel. Carefully pour the contents of the mason jar onto the cloth (which is in the metal cup). Make sure to get most of the weed particles out of the jar. Gather up the edges of the cloth and squeeze the remaining liquid out of the lump of weed into the metal cup.

 

 

Step 1a
You should now have a quantity of dark green liquid in your metal measuring cup. It is possible to extract more THC oil from the remaining pot. Dump the pot from the cloth back into the mason jar and repeat step 1. You now have twice as much liquid in your metal cup upon repeating the first step.


 

Step 2
Be sure to use an electric stove in this step! (If you don't have one, read Step 2a).
Take the metal cup containing the green liquid over to the stove. Turn one of the electric knobs on LOW setting and place the metal cup on that burner. USE A FAN over the stove to remove the alcohol vapors during this entire step. Watch the liquid closely. It should only boil slightly.  Never raise the burner temperature above MEDIUM LOW! We need the liquid to cook down until it's slightly thick. This may take some time so be patient!

 

Once the liquid starts to thicken and turn darker, remove it from the heat. Never let it get too thick or it will be too difficult to work with. If you do accidentally make it too thick, just add a small quantity of the grain alcohol to the metal cup and swirl it around until it's thinner.

 

Let it cool down to room temperature inside the metal cup. It should be thin enough to be poured into the eye-dropper bottle easily.

 

You now have your final product: THC oil. It's necessary to have some grain alcohol left in the resulting liquid so it's easy to work with. This will not affect the potency of the oil.

 

Step 2a  (This part is for the people with gas stoves).
Do not use a gas stove to cook down alcohol! The VAPORS will EXPLODE! You'll have to have patience to complete this step. To get the correct, finished product, put the metal container in a place where it won't be disturbed. The alcohol will have to evaporate on its own. Keep it in a slightly warm area with decent ventilation. It may take days, but the final product is worth the wait!

 

Once it's evaporated, vaporize with a glass nail and oil dome.  Cut in half a 2 liter bottle to catch the smoke.
