THC-A Crystalline Hash is the holy grail of cannabis potency. The process starts with a cannabis extract. Then, cannabis extract is mixed with acetic acid and hexane. Those chemicals work together to dissolve the plant matter but preserve the THC.
Once the extract, acid, and hexane are acquainted, they’re put through a traditional filter. The solution all goes in a rotary evaporator, which looks and sounds more complicated than it is. Rotary evaporators use varying degrees of pressure, heat, and motion to pull apart the different materials in a liquid.
By the time the rotary evaporator is finished its cycle, a mixture called Δ9 tetrahydrocannabinolic acid is left.
To refine the mixture more, a process called chromatography is needed. There are a few different kinds, but the purpose of chromatography is to remove impure elements from the solution. To do this, chemists add more chemicals to the mix. One called Sephadex-LH20, another called dichloromethane. Then good old-fashioned chloroform is added.
Once the hash has gone through chromatography, it doesn’t look much like any marijuana product you’ve ever seen, and more like something Walter White would be selling.
The THC-A Crystalline isn’t pure yet. Those crystals will still have a handful of unsafe chemicals like chloroform. So, the crystals go back in the rotary evaporator which pulls the solvents out of the THC.
To make THC-A Crystalline consumable and heighten its purity, more unwanted chemicals must be purged. The crystals are dissolved in methanol, which looks, smells, and tastes like alcohol people drink, but is totally toxic to humans. A traditional filter takes away all the leftover residue. Then to pull the methanol out, chemists put the mixture back in the rotary evaporator again.
Now the crystals are left to dissolve in pentane, which extracts more parts per million of non-THC material. For the final time, all of that goes back in the rotary evaporator. That long process results in 99.96% THC.
Usually, people will add terpenes to add some flavor to the high. By all accounts, pure THC in this way tends to hit much faster than regular weed.
For those tempted to try this, all anyone really needs to make crazy hash is a bubble bag and a bunch of weed.
