DOES CBD NEED A HECHSHER?

HERE IS WHAT WE DISCOVERED

After conducting extensive research, we discovered that most distilleries add non-kosher oils, flavors and terpenes to their product. Upon further investigation we learned that some companies use grape seed ethanol in the extraction process which is a significant halachic concern according to most rabbinic opinions. Another concern is that the oil is heated during the extraction which introduces a host of other halachic complications.

We also observed that the same filling stations and equipment were used for many different non-kosher products.
