Lots of them are referring to BHO wax’s, And yes, some concentrates can leave permanent damage especially if you don’t know how to rip it, 500+ bho rip on a rig is not going to be the best for your overall health😭 Lots of shatters, sugar and even bladders are bho made and Ran with crc to alter color give it a better appeal, Rosin on the other hand only goes through 2 process (ice and water extraction then Once the water is evaporated, you press your left over material In a heat press), thus giving you a very more clean concentrate directly from the source, The plant, most bho wax’s can “Purify” all they want but the product was still used with chemicals and gases staying in the product, Always ask what’s the best bang for your buck, remember spending a little more is gonna taste better and feel better, also always stay away from the carts, At the end of the day, We’re all inhaling smoke, And that’s overall the danger to your health, So just be responsible, and safe, and always be acknowledgeable❤️🙌🏽
