The Definitive Green Dragon
Here is the very successful result of a considerable amount of research into
the elusive and magical Green Dragon.
This is a simple and efficient 4 Step process.
1/8oz high quality cannabis
2 oz Bacardi Rum – 151 proof
1. Chop cannabis very fine (coffee grinder works great)
2. Place in a shallow pan (a sheet of aluminum foil works great) and bake at
325°F for 5 minutes.
3. Remove from oven and place cannabis in 2 oz of 151 proof rum (use a small
wide mouth mason jar)
4. Simmer in a water bath for 20 minutes. Maintain temperature of the
rum/cannabis mixture between 170°F.
5. Strain the mixture and store.
One milliliiter (one full eyedropper) is very nice. Two puts you in space.
But you must self-titrate (test it on yourself) as each batch will be
slightly different. Effects take up to 1.5 hours to begin (at least in
myself) and lasted for 5 hours (1 dropper) to 7-8 hours (2 droppers).
I place one eyedropper (1ml) of Green Dragon in a small glass. I then add a
small amount of water (1-2 ml) and drink. Do this on an empty stomach for
best results (about 20-30 minutes before eating a main meal is good).
Process details—references and rationalizations:
1. Chop the cannabis
More surface area gives means a faster and more efficient extraction.
2. Bake the cannabis.
This converts THCA to THC via a decarboxylation reaction.
In whole-plant cannabis, THC
content is expressed as THCA (tetrahydrocannabolic acid) prior to
decarboxylation into THC, which takes place when cannabis is heated in the
oven, and smoked or vaporized ingestion. THCA is a mild analgesic and
anti-inflammatory but does not have good affinity with our CB1 receptors, so
in order to make a THC-rich tincture that has many of the same therapeutic
effects as smoked ingestion (including rapid absorption, quick relief and
ease of self-titration), we must convert the THCA in the plant matter into
THC prior to extracting it through an alcohol soak. (from Vancouver Island
THC vaporizes at about 380°F. We
want to heat the cannabis to convert THCA to THC, but keep the temperature
under 380°F. That is why 325°F is used. Between four and five minutes your
oven (and house) will start to smell very strong. This is the time to remove
the cannabis from the oven.
Notice also that there is considerable misinformation regarding heating the
cannabis. It is true that you don't have to heat it to extract both THC and
THCA, but the amount of THC in whole plant preparations is relatively small
compared to after decarboxylation of the THCA. So if you want to maximize
the strength of your tincture you must heat the cannabis prior to
3. Use the highest proof alcohol available.
Where I live this is Bacardi 151. The more alcohol the more efficient the
extraction will be.
4. Simmer the mixture.
This is one of the areas that seems to be most debated. Many guides call
for placing the normal cannabis into the alcohol and waiting 2
– 6 weeks. The main concern with heating the alcohol is that it is
“explosive” (not exactly true...it is however flammable).
The purpose of the simmering is to heat the alcohol mixture to improve
extraction rates and efficiencies. Heating during extraction increases the
motion of the molecules (basic physics/chemistry) and drastically decreases
extraction times. The boiling point of pure ethanol is 173°F (78°C). We will
use the water bath to heat the rum/cannabis mixture to just below the
boiling point of ethanol.
Heating the alcohol mixture can be done very safely using a hot water bath.
You will need an accurate candy or quick read thermometer. Place about 1
inch of water in a wide, vertical-edged pan (9” diameter x 3” high). Bring
the water to a low simmer. The rum/cannabis mixture should be in a small (1
pint) mason jar. Do NOT cover the jar.
Put the thermometer into the mason jar and place into the simmering water
bath. Bring the temperature of the rum/cannabis mixture to about 170°F. The
alcohol should be just barely boiling.
You should have the oven fan on high. You will notice that any alcohol fumes
are mixed with water vapor from the water bath and vented out the fan. This
combined with the fact that you are trying not to boil the ethanol makes the
process quite safe.
5. Strain and store.
When you are finished with the extraction you will be left with about 1oz of
green dragon tincture after you have strained the extract. Notice that one
ounce of the alcohol has evaporated. See the tips below for a good way to
strain the tincture.
A standard eyedropper will transfer about 1ml (or 1 gram) of liquid. There
are 29 milliliters in one ounce. So you should end up with about 30 or so
full eyedroppers (30 milliliters) of Green Dragon.
The liquid should be dark brownish-green and smell like cannabis.
6. Dosage. Titration.
Everybody is different. It takes me between 30-90 minutes to feel the
effects of Green Dragon (depending on how much food is in my stomach).
I had tried a tincture someone had made using the cold extraction method
with the same amount of cannabis and found that 5 ml (5 full eyedroppers)
did pretty much nothing.
Using my Green Dragon technique I find that one dropper will bring effects
on in 30-90 minutes and last 5 hours with 1.5 hours of lingering
Two droppers gave me a "spiritual dose" (as strong as any brownie I ever
had). Effects lasted 7-8 hours with lingering effects for 2 more hours.
This means that 1/8oz of good cannabis yields about 30-34 doses of tincture
(1 dropperful is really all I need). For me it is much more pleasant than
smoking (I've stopped smoking entirely).

Combined Tips and Techniques
Below are the combined tips and answers to questions that have accumulated
over the last 6 months.
1. Baking Temperature/Time.
I use 325 Farenheit for 5 minutes. Although this will change depending on
the type of pan you use. With a gas oven and aluminum foil for 5 minutes was fine. However with an electric oven, a sheet,
and parchment, I needed a few more minutes. Keep a close eye on it.
Note that OKSmokey uses 20 minutes at 200°F. I haven't tried this but he has
had good success with this temperature.
2. Double the Recipe?
Sure, why not. It should be fine. But I prefer to err on the side of caution
and would probably do the extraction twice with a self-titration in between
You will have to figure dosage with each batch. And you must test it on
yourself. The way to do this is through titration (a fancy chemical term
that means to determine the concentration of a solution). The concentration
of GD will change based on the strength of the starting material, the amount
of alcohol you boil off during the extraction, the efficiency of your
oven work, etc.
Start with one or two full dropperfuls (not drops!) and swallow them down.
Check the time and note when you first feel effects, when you peak, the
intensity of the peak, and how long it lasts. Make sure you can reproduce
your titration (empty stomach, time of day, diluted in water?, etc). If you
like what you feel, great. If too much or not good enough try again tomorrow
with a different amount. With two points (high and low) you should have a
pretty good idea of how it works on your body. Of course it might be
different on someone considerably bigger or smaller.
For instance one batch I made was unbelievably strong--1 dropperful and I
was flying. The next one took 3 dropperfuls for same effect (but the
solution was more dilute as I ended up with 1.75oz instead of 1oz of final
GD, the pot wasn't as good, and my oven time was a bit too short since I was
using an unfamiliar oven and a baking pan instead of just aluminum foil).
4. And as always--don't put the stuff in your eye ;-). And don't put
it under your tongue because it burns. I now place the GD in a tablespoon
(or so) of water--yum. I actually like the flavor as it is sort of floral. I
also store mine in the fridge, but don't really know if this matters.
5. How much is in an Eyedropper
An eyedropper holds about one milliliter of liquid, depending on how hard
you squeeze the little bulb. For water based solutions one milliliter weighs
about one gram. Thus each full eyedropper contains about one gram of liquid.
Since there are about 29 grams in one ounce, you get about 29 full
eyedroppers in every ounce. The eyedropper I initially used measured 34 full
droppers in an ounce.
Also I use the nice blue two-ounce dropper bottles from the health food
store that are used for essential oils, tinctures, and/or other extracts.
6. Leaf vs. Bud
I have not tried the extraction with leaf. But you would obviously need
loads more. The problem is you will also need much more alcohol. My guess is
you should use somewhere on the order of 10 parts alcohol to 1 part leaf.
Then once you are finished you will want to remove the spent leaf, and then
concentrate the alcohol by boiling off most of it (using the water bath of
course) until you have one ounce of GD remaining.
7. When is it Ready
Right away. That is one of the nice things about this extraction process.
I find that after a week in the fridge (that's where I store mine) the
flavor seems to mature into a heady, slightly floral elixer with bud
overtones. I find it rather pleasant.
9. Isopropyl Alcohol
DON'T USE IT!
10. Using an Ounce
The guide should scale nicely from 1/8 to whole ounce. But, unless you have
experience with smaller batches I'd recommend sticking with the guide as
written. It would be a shame to have something go wrong with a large batch.
I strongly recommend making the GD a couple of times before trying to scale
11. Pre-Heating the Pot - Color Changes and Vapors
Bake the pot at 325 degrees Fahrenheit for 5 minutes. I chop mine in a
mini-prep (or chop by hand) until it is quite fine. Then I spread it out on
a piece of aluminum foil which is placed directly on the oven rack. If you
place the foil on a pan you will need to account for the additional
mass of the pan which will increase your oven time. Pre-heating should
stink up the house. I turn on the stove vent fan. I also do all my oven work
at night after neighbors are in bed.
I look for two indicators that the pot is properly pre-heated. First, I look
for the pot to change color from it's initial shade of green to a much
darker greenish-brown (or brownish-green). I assume this represents not
browning (burning) of the leaf but rather the denaturation of the
chlorophyll in the leaves.
Second, I look for a slight amount of vapors to rise off the pot. Since the
temperature is well below the vaporization temperature of THC, these vapors
probably consist of compounds that vaporize at lower temperatures (like
12. Extraction Temperature (revised)
I've had good success with extractions at 170 degrees fahrenheit. At 170 the alcohol mixture will be slightly boiling. Note that this
is alcohol boiling not water boiling. Alcohol boils with very fine bubbles
as opposed to the rolling boil of water. After 20 minutes the alcohol should
be reduced by about half.
13. Green Dragon Final Color and Smell
The green dragon should be a greenish-brown color (more brown than green).
If it is emerald green and smells like grass (from the cholorphyll), it will
be weak. Emerald green indicates that the pre-baking was not sufficient. The
GD should smell like bud, somewhat floral.
14. How To Recover The Green Dragon
When you are done extracting you will have one ounce (or so) of GD. But it
is mixed up with the 1/8 oz of spent plant material. Here is how I recover
the maximum amount of my extract.
First, I strain it through a regular kitchen mesh strainer. I use the back
of a spoon to force out as much GD as possible.
Next (this is the cool part) I use a garlic press to squeeze the remaining
leaves. My preference is a Zylis Garlic Press because it has a plunger
mechanism, but any press should do. I then put the squeezings into the
plunger in batches, and squeeze the holy GD out of it. This trick has
increased my overall recovery by about 15%.
There ya go Green Dragonsters. Good luck and Enjoy.
Special thinks to Master Wu who spent countless
hours mastering his process. I did not write it, I only display it to
share this wealth with all who would use it.
Note: Green Dragon will make you VERY high!! Start with the recommended
amount, any more may be more than you bargained for.
