I don’t think anybody is going to jail for hemp oil in any US state these days. I may be wrong, but I don’t think so.
Try bringing your hemp oil through US customs and see.
By the way there is a BIG difference in “hemp oil” and “hashish oil”, hashish is a potent drug, much stronger than pot, and is what Britney confessed to having with her.
Hashish contains essentially the same active ingredients found in marijuana, except in a more concentrated THC form. Hash oil is a concentrated cannabis extract that can be smoked, vaped, eaten, or rubbed onto the skin. The use of hash oil is sometimes called “dabbing” or “burning.”
Hash oil comes from cannabis plants and contains THC (delta-9-tetrahydrocannabinol), the same active ingredient as other marijuana products. Hash oil is more potent, containing up to 90 percent THC. By contrast, in other cannabis plant products, the average THC level is approximately 12 percent
