Rosin is a marijuana concentrate made in an extraction technique that manipulates fine hash using heat and pressure. It is popular among commercial extract manufacturers because it requires very basic technology to produce.
Because no solvents are used to separate the cannabinoids and terpenes from the plant, rosin has a high overall purity with no residue. Its price of production is also very low, since only heat, pressure and sift bags are used to make it.
Whether using a vaporizer or dabbing rig, there are several options available when consuming rosin. It is usually vaporized in low temperatures to experience the terpene signature. Others go with higher temperatures for bigger and thicker vapor.
One reason for rosin’s newfound popularity is that the process does not require the use of any foreign substances. Instead, rosin uses a mechanical process involving heat and pressure to extract the resin from the plant! No butane and/or propane!!
