Distillation can't effectively be used to remove specific cannabinoids.

Really?

"Because fractional distillation of cannabinoids involves separating all cannabinoids and then adding them back together to achieve particular blends, both CBD isolate and full-spectrum CBD distillate can be made THC-free. For THC-free products, fractionally distilled THC is removed. This process adds value to the product and increases cost to the consumer, but it’s worth it for people who need to be sure that there’s no THC in the product. Fluid distillates can be used sublingually, topically, orally, or through inhalation. Fractionally distilled THC can also be used on its own as THC distillate. "
