These instructions wont handle every detail but it is still worth listening to as this is the most efficient and healthy way to extract THC with the use of alcohol.
First of al the ingredients:
Your weed; There is no need to buy expensive weed or to select the best cuts. Although a high THC% is preferred because there will be less sugars and other shit mixt in your end result. Leaves and stems can also be considered usable, but it has pretty much the same downside.
Alcohol; The alcohol is a more important part than the weed. What you want is Medicinal 99% alcohol. And if you cant get it, try to find something similar. What you are looking for is the least possible amount of colour and flavorings. Moonshine does the trick, but it contains a bit more "invisible" organic material in comparison.
Ratio; It depends on the prize of the weed and the alcohol in your country. If weed is hard to get, use more alcohol for a little more result.
Why the purity is so important is because you want to end up with nice white crystals or a solution that you can keep in a waterbottle without being noticed.
Step 1 (skippable, repeatable) "Cleaning the weed": This is the process of cleaning out the stuf you dont want in your solution. This is actually quite simple. You put your weed (dont grind it yet) in a pan of warm/hot water. Dont boil it because it loosens the structure of the weed. Keep the weed in the water for a while like a bag of tea. What this does is, it removes the coulors, sugars, aroma from the weed. This sounds stupid but THC wont be wasted if done well because it doesnt dissolve in water. Now, when the water changes colour you can seperate the weed from it. This process is repeatable until the water doesnt get any colour no more.
Step 2 Extracting: In this process you will dissolve the THC into the alcohol. First of all you dry your weed a little so that it doesnt need to be in the alcohol that long for the THC to get out. If you are using both stems and buds, separate them now because you want to extract from the stems first to get more efficiency. Chop/grind the weed into very small pieces but large enough to filter out. (You do not want to use a blender). Now, we first do the stems and leaves. After that you repeat it with the buds. If you didn't separate them from buds, don't care too much about it. Put the chopped weed into the alcohol, and heat it up. DOnt let it boil YET. Keep it warm with a lid on the pan for like 10-20 minutes. Afther that is done, poor it through coffy filters (or T-shirts) multiple times until it is a clear solution. This solution contains around 85%-90% of the THC that was inside the weed. Reed step 3 or have fun with it
Step 3 Processing: What you have left is basically a solution of nothing more than the alcohol and the THC. It is quite nice to drink pure, like a very strong vodka with a minty(Weed) flavor. And it can also be mixed with other drinks. If you do not like the alcohol and only want the THC you can boil the alcohol out. IF you do that, eventually this thick solution will get a slightly brownish tint like icetea. This can also be mixed or consumed directly. There is No need to boil it further. IF you want the crystals there are 2 ways to get them. For both of them you need wooden skewers .
The first way is to put the product in the freezer with these wooden sticks in it. Make sure the freezer is on max power, and the THC will crystalize on the sticks in nice white crystals. You can wait a few days and take these sticks out to dry. The solution still contains a little THC, and can be re-used by pouring it in "step 2" the next time. The crystals can be scraped of and kept in a small container. THere will be more than you think if you did everything right!
The other way is to poor water into the solution and boil out the remaining alcohol. Bring it just above freezing point with the sticks in it and the THC crystalizes. I dont really know which is the most efficient way.
You can also soak a piece of paper with the solution and let it dry. This paper can be taken to school or work without being noticed. And it is realy cool smoking those "Hollow joints" that contain way more THC than a normal one. ^^
People who use oil instead of alcohol leave a lot of THC in the plant, evaporate a lot and destroy a lot creating a crappy nasty resin that isnt worth it at all.
Please feel free to ask if you have questions. I will come with my pics (or vid) soon if you guys are interested
