What's not making sense. When you make rosin it's no longer a raw bud. When you wash buds to make hash rosin out of bubble hash some terpenes go in the water. Vaping bud is different than vaping oil. Oil will never be the exact same as the buds the better the extractor is the closer it will be to the raw bud. Don't believe me make bubble hash and taste the water your losing something. When you heat bud in a rosin press your losing something. When you purge butane out in a vacuum your losing some flavor. Not saying low temping you don't get more flavor than bud but it is a different experience. Oil has more flavor then bud because it's concentrated but you lose the smell that comes out when you open a jar especially with butane they evaporate at same temps. Dabs have more flavor because you are vaporizing like a half gram of weed at once
