In the relatively short time people have been “dabbing” the oily extracts of cannabis, the production methods for these products have evolved at a rapid pace.
The vast majority of marijuana concentrate on the market for the last decade or so was typically extracted from the plant using solvents, a process that uses abrasive chemicals like butane to strip trichomes from flower to create an oily substance that can come in a wide range of consistencies depending on technique.
But a tried-and-true method of extracting concentrated oil came to save the world from ingesting harmful chemicals in recent years, as pioneers began squeezing oil from their source flower, just as people had done to make essential oils and cooking oils in the past. By combining heat and pressure, one can yield precious extracts from the source material with relative ease.
At first, consumers were using rudimentary tools like hair straighteners to complete the process of making rosin, as industrial hard presses were expensive and hard to come by. But as time went on and consumers realized that rosin offered the potency they sought without the harsh taste and aftereffects of solvent-derived oil.
Now, with consumer-friendly devices like the ROSINBOMB Rocket, the average oil user can have a heated and pressurized hard press at home without spending thousands of dollars. As someone who had purchased and subsequently destroyed roughly 30 hair straighteners before a consumer model hard press was available, this is a revolutionary development.
Like the organic and GMO-free movement in the agriculture and food industries, flower rosin offers a pure and healthy solution to those worried about the dangerous levels of chemicals and other solvents in alternatively produced oils. Rosin keeps producers honest, as the final product directly reflects the quality of the source material, whereas other extraction methods can hide imperfect flower and outside factors like mold. Pressed rosin will be the concentrated version of whatever you put between the plates -- for better or worse.
Rosin doesn’t just benefit your lungs with its purity, the pressing technique also allows the extract to retain the aroma and taste of the original flower, whereas solvent-laden concentrates are overpowered by a metallic or chemical essence. While the health benefits of rosin make it an easy choice over its solvent-filled counterpart, the public safety benefits are enormous as well, as producing butane hash oil can be extremely dangerous and put producers at serious risk of injury or death -- pretty much one of the only ways cannabis actually could kill you.
Though producing rosin with a hard press comes with some upfront equipment costs, they are considerably less expensive than the closed loop system you’d need to safely produce butane hash oil without ‘sploding your whole house and making your mom think you run a meth lab. With its low cost production, high purity, and immense versatility, it’s no wonder rosin’s popularity among connoisseurs has grown exponentially.
