Alright, well if you are a medical marijuana patient, I'm sure you have seen the "Tinctures" that are sold at dispensaries, which include not only "Green Dragon" like alcohol tinctures, but also "Food glycerin" drops (which are also put in the candies, bubblegum, and many other delicious edibles.

Now there are alot of recipes for these tinctures, many vendors keep their own secret as it is a specific ratio for the "Green Dragon" mix, or a specific way to enfuse THC into glycerin or alcohol and make it into drops or edibles.

I am going to experiment with how to make these tinctures, and you all can join along on the ride. I've talked to a few people at dispensaries, most seem to say that using glycerin is all about the amount of time you leave the ganja or hash in the glycerin, and the heat it is at. Many call these "Sunshine tinctures" because they mix their ground up stuff with the glycerin, then leave it on a windowsill to be heated by the sun for anywhere from a few days to a few months. some say if you heat it in the oven to start the reaction (at about 300-325 degrees F), or even in the vaporizer it works faster. some disagree and say its about the 'soak'.

But from what I've gathered, this is what I'm starting with: I have two mason jars. Inside one is "Grapefruit" medical marijuana (as seen below....i covered up the dispensary's name). There is 1.5 grams of weed and ~30ml of glycerin (97%+ vegetable glycerin....DO NOT get the cosmetic kind).

Why 30ml (2 TBSP)? Because each 'eye dropper' bottle i got to put the tincture in is 15ml. This was recommended by someone at the dispensary so that you have .75-1g used per bottle of glycerin (which usually cost between 25-40 a bottle of 15ml). Supposedly if done right, the glycerin can absorb very high amounts of the THC from the original, far beyond that you get from smoking, and even a little better than alcohol extraction.

In the other jar is 15ml of glycerin (1 eye dropper bottle), and roughly .75g of keif from my grinder. This is going to be my 'hard hitter' im hoping on. the Grapefruit is more sativa, and less concentrated so im guessing it will be weaker.

mason jars are sealed tight, and as you can see i am double-boiling them. it has been said that this increase in heat speeds up the process, some people even double boil theirs for 3 days straight to make it. Here is what I am going to do: double boil these a bunch today, then stop and dry and just leave them in a dark warm place. I DONT want to put these on the windowsill because as anyone had read, light degrades THC so it seems like the "Sunshine tincture" would be more potent if jars were simply covered up, but still got the heat - after all, its the slight elevation of heat that we are looking for in that windowsill.

ill see how this progresses. checking every day on the jars, possibly putting them back in the double boil while im home for a little while. i'll keep this up for a week or two, then try 3 drops under the tongue and see how it is. if its not as good as hoped, itll go back for another period of time.

i know a long rambling post..... but you guys know me with my details. the TrainWreck could have something to do with it too. anyways, any questions feel free to ask. if anyone has tried this before, any input would be appreciated!

*edit* heres a link to a previous discussion on tinctures, i have a post half way down the page with more info on the glycerin: http://greenpassion.org/f35/re-creat...-strips-13946/

Gr8t thread Die I want to make this so much. I have been looking around for things like eye droppers/bottles and I like the idea of food grade glycerin.

I tried a couple of these maybe 7 months ago with little effect so I put the idea away with it. Then I spoke to a few folks that said due to the high amounts of morphine I was on it probably didn't work. Well now I'm down to almost none for pain killerz and I like the thought of no alcohol too!

Where did you get the glycerin a health food store? I still need to find droppers and bottles. I will try my local pharmacy for them. I have no head/glass shops near me smaller town.

I wanted to add some flavors to mine I was thinking the health food stores for something mild and wild maybe.

I will watch this thread to learn how you are doing. Good luck.

I bought my glycerin and eye dropper bottles online, but i know you can get the bottles at many pharmacies and drug stores for cheap. i wanted to order a bunch so i got them online. as for flavors....i dunno if they have them near you but at most of the head shops around here they have flavor drops for both bong water, and drops that you can put directly on your weed (its made of food glycerin! haha). anyways, you can also use natural food flavors that can also be bought at bake stores or online.

Great post! This makes me want to make up a glycerin tincture and just leave it be as well. I've got glycering from a health food place lying around too and I could probably spare a few grams for this experiment. God knows how much herb I've used in the name of experimentation. I also have heard that it's all about the time, which means that you have to wait ~2 months to see results. But please keep this thread updated with your results please!

I will go out Friday morning and get some glycerin from my health food store and use 30 grams of my latest harvest. Since there are many variables like time and heat etc I want to use enough so I can have many bottles going at a time to see which is better for the end result.

I will post my findings also so we can get some good data for others so they wont need to experiment.

Hi there Die I went out a got some glycerin B.P. I was told it was food grade and edible I hope it is the right stuff?

I was able to use 5 gr. BBHP I harvested last month per the one bottle of glycerin B.P. 100ml size. Ground it all up and poured it into a clean mason jar threw the lid on tight wrapped it with a towel and left it on my window ledge in full afternoon sunshine. I will check on it next weekend to see how it did in just 1 week. Hope it stays sunny.

I find the glycerin B.P. is pretty thick I hope it will thin down a bit over time? Do we need to strain it at some point? Fingers crossed I hope this turns out.

yes it is quite thick. it thins and mixes better when heated a bit. almost like maple syrup its get more watery the hotter it gets. yes you will have to strain it through a cheesecloth before you put in bottle for drops. best way to do this is to double-boil it so it heats just and can easily pour through

I have double boiled the jars a couple more times for about 2-3 hours each time. Tried a bunch under the tongue of the Kief one.... nothing special a little buzz. Not that potent yet. More updates in another week or two

I started another one this weekend. I picked up some Wrey and Nephew Jamaican over proofed rum. I used 100 ml with 5 gr of my bud ground up. It is soaking in my window sill covered with a dishtowel to prevent sunlight.

The one I did with glycerin is just a week old and I have double boiled mine as well and it is turning a nice colour now. I will leave them for another week before testing. I can't wait to try them.
