The CBD industry has a dirty little secret that may leave customers feeling let down by their latest cannabis-infused purchase.

The practice, known as weed-washing, occurs when companies add hemp oil that contains little or no CBD to their products in an attempt to financially benefit from the enormous popularity of the compound found in cannabis.

The new trend appears most common in the beauty industry, according to U.S.-based publication, The Fresh Toast, and risks alienating consumers who do not experience the CBD benefits they were promised.

Instead of adding CBD-rich hemp oil (extracted from hemp flower) to products, some companies are using oil extracted from the seeds of the hemp plant that contains only miniscule levels of CBD.

Beauty Independent has reported that some manufacturers play this up by adding cannabis imagery to packaging and employing buzzwords such as “calm” and “bliss out” to further muddy the waters. The website names Sephora, Origins and The Body Shop as among companies believed to be misrepresenting the level of CBD in some skincare products.

There is significant consumer pressure to make CBD.

The U.S. Food and Drug Administration (FDA) updated its consumer update last year to note that the agency does not have sufficient scientific evidence to “conclude that CBD is generally recognized as safe among qualified experts for use in human or animal food.”

The FDA has reported that while there is significant consumer pressure to make CBD — a non-psychoactive component of cannabis — more available, it is different from any other chemical that the agency has had to grapple with. It cautioned that it could take years to fully work out regulations and, in the meantime, only one prescription CBD drug has been approved to treat two rare forms of epilepsy.

This unregulated environment has led to an explosion of CBD-infused products promising to help cure anything and everything in a bid to get consumers to open up their wallets.

Label should have “full-spectrum hemp,” “cannabinoid” or “cannabidiol” listed among the ingredients.

Teadora, a company that sells all-natural beauty products, has produced a set of guidelines to help consumers stand a better chance of getting the real thing. On the list is to make sure that products pushing the benefits of CBD actually have “full-spectrum hemp,” “cannabinoid” or “cannabidiol” listed among the ingredients, instead of just “hemp oil.”

Be wary of where the purchase is coming from, too. Not all CBD companies were created equal and a little research can go a long way.
