Ingredients Matter

The cannabis plant has special properties

Cannabis can soak up pollution from air, soil and water.1-3 People use it to help clean up dirty places.4-6

Other things make the plant more complicated

The way cannabis is grown affects what kinds of cannabinoids (molecules) are in the plant.7

Strict rules help make sure FDA-approved medicines are safe and high quality

Cannabis can soak up pollution, and the cannabinoids can change in the plant.2,7 That’s why strict rules are needed to keep products safe and consistent. FDA-approved medicines follow these rules, but many CBD products don’t.8

Over a decade of research, scientists have
found CBD products to be unreliable.

There are problems with under-regulated CBD products. Buyers should be cautious.

Why do high standards matter?

Below are side-by-side comparisons between FDA-approved medicine and under-regulated CBD products

Checkmark approval icon

FDA-Approved CBD

The label on the package MUST match the contents.21-23

This means there is quality control ensuring consistent concentrations of CBD with every batch.

Warning or caution icon

Under-Regulated CBD Products
(Non–FDA-Approved)

Research shows that many under-regulated CBD products are mislabeled.14, 18, 20

This means you don't know how much CBD there is.

Healthcare provider and patient icon

FDA-Approved CBD

Clinical trial research shows how much CBD to take and what to expect when taking it.11,24

This means the Healthcare Provider can properly advise you on dosing you and watch for adverse effects.

Question mark or uncertainty icon

Under-Regulated CBD Products
(Non–FDA-Approved)

Without clinical trial data on these products, we don't know if it will work for medical conditions.

This means the Healthcare Provider doesn't have the correct information to advise on how to safely take the product.

Shield or purity icon

FDA-Approved CBD

Manufacturing follows strict GxP and the contents must be free from contaminants.12

This means you have purified CBD that is free from contaminant.

Contaminant or hazard icon

Under-Regulated CBD Products
(Non–FDA-Approved)

Research shows that many under-regulated CBD products can be contaminated.19, 20

This means these products may contain unwanted cannabinoids, like THC, and may be contaminated with toxic elements, like heavy metals or prescribed.

Insurance card or prescription icon

FDA-Approved CBD

FDA approval is required before a drug can be marketed or prescribed.25-26

This means it can become available by prescription from your HCP and may be eligible for coverage by medical insurance.

Retail shelf or store product icon

Under-Regulated CBD Products
(Non–FDA-Approved)

Without FDA-approval the CBD product cannot be prescribed and is not eligible for insurance coverage.25-26

This means it is just another product on the shelf.
