This will help to decarboxylate all of the remaining THCA from the original nugs into THC. (Use both thermometers again to monitor your temperature. Be advised, raise the temperature of the oil in the “outer” pan above 220℉ in order to get the liquid THC in the “inner” jar to remain steady at 220℉).
You can also use a hair straightener and wax parchment paper to press rosin out of medium-sized, densely-packed marijuana buds in order to make super potent liquid THC. It’s actually a lot harder to do than it sounds, but basically the general idea is to sandwich a nice dense nug between two pieces of the parchment paper. Then, squeeze it between the blades of the hair straightener as hard as you can. Do so until thick, THC-filled goo (rosin) comes oozing out of it. If your technique is up to par, you can consistently make about 0.5 g of ultra-potent THC rosin from about an eighth of dry flower – maybe even more if you’re a DIY rosin-pressing expert. Regardless, once you’ve extracted the THC using this technique, you’ll need to add a terpene solution of some sort in order to turn the gooey, gunky mess into workable liquid weed that you can either vape or administer under your tongue . Note: there are serious dangers with any one of these techniques to make THC oil. This is why we DO NOT recommend that you do any of them. Instead buy your liquid THC from a trusted, reputable dispensary. One of the most inherent dangers of making liquid THC is from butane gas accumulation.
We didn’t go over how to make liquid THC using butane here in this article, but it is nevertheless a popular method among DIY’ers . Basically, what people do is pour butane (lighter fluid) over a bunch of plant matter packed tightly into metal tubes. The butane runs over the plant matter and extracts the THC, oozing out the bottom in the form of a sticky, gooey liquid THC. The problem – and it is a serious and possibly deadly problem – is that without proper ventilation, fumes from the butane can accumulate in large volume as it sinks down to the ground (butane gas is much heavier than normal air). And triggered by something as simple as a water heater pilot flame or a tossed cigarette butt. Whatever kind of personal decisions you make in terms of how to make liquid THC, just do so at your own risk and we definitely don’t recommend making liquid cannabis. The best way to store liquid THC is in a glass dropper bottle jar, similar to an eye drop bottle. Also, opaque bottles that are dark green or brown are a much better option than clear glass bottles. They do a better job of filtering out damaging UV rays. Store your liquid THC in a dark glass vial or dropper bottle. Then, keep it in a dark, climate-controlled environment out of direct sunlight. Keeping it in the refrigerator is also not a bad idea at all as this will maximize shelf life. Liquid THC can come in many different viscosities and physical appearances depending on the strain that was used , the type of alcohol that was used, the temperature during extraction, etc. Realistically, there are dozens of different factors that can contribute to the appearance of a quality liquid THC tincture. Generally speaking, though, a good liquid THC will be pretty opaque or cloudy. This means light will not be able to pass through it. Next, it will range in color from a light, limey greenish to an ultra-dark, tarry, almost black goo. The best THC oil is typically a beautiful shade of amber or gold. Whatever the case is, your liquid THC should not be clear. Additionally, there shouldn’t be any visible flakes, plant matter, etc. What’s the safest (at least in terms of general health) way to use liquid THC? To administer it as droplets underneath the tongue.
This area of the mouth has many glands and capillaries (tiny blood vessels). You essentially receive a direct administration of THC right into the bloodstream.
If you administer below the tongue, place a single drop or two and hold for about 60-90 seconds before swallowing. Of course, you can also vape liquid THC using a vape pen , e-cigarette device, or some other kind of portable vaporizing unit. Be advised though, that if the liquid pot contains any amount of propylene glycol (PG) or polyethylene glycol (PEG), you risk inhaling formaldehyde if the vape burns the juice at a temperature much higher than 200℃.
