Avoiding the Dangers of Mystery CBD through Vertical Supply


Soil through Retail Sale,

That’s our testing doctrine here at Schools & Tools.

ALL of our Hemp is grown at Sonnen Farms in Aurora, OR – where the soil is certified organic and free of both heavy metals and pesticides.  Because of this, we know what’s in our plants, and we know what’s in each value-added product.  Flower, trim, oil, distillate & isolate – all tested for heavy metals, pesticides, and potency at every level, and used in everything we sell.  We work hard to avoid any threat to both our products and our consumers.  Test results are completely transparent, and made readily available to the consumer.  We’re about to tell you why that’s so important to us…


The Threat of Dilution.

All CBD products imported from foreign markets have to meet US standards, but many have found a way around this.  Once diluted into tinctures and/or candies, their oils and isolates now “pass the test”.  This doesn’t mean the base product was okay to begin with, and it doesn’t mean the value-added product is safe.

The Threat of Diversion

Diversion is better described as the old “bait & switch”.  When a product is sent to be harvested, tested, farmed, dried, or processed in any way, it’s now out of your hands.  The risk here is that you’ve lost your clean product, and you now have an unknown liability.  It’s just another reason we test at every level.  We also work with cGMP facilities 

who have introduced genetic markers into their plants, and can now trace those markers throughout the supply chain.  When we receive a COA, we know it’s for our material.


The Threat of Cross-Contamination

Cross-contamination can happen at any level of processing.  Again, testing at every level helps us avoid the distribution of a product that may be tainted.  THC, pesticides, heavy metals – they can all be transferred from batch to batch.  Some contaminants are airborne, some manage to hang on to processing machinery.  We work with the highest quality processors who take whatever steps necessary to eliminate the possibilities of cross-contamination.  And again, we test Again.


CBD is not CBD is not CBD. Knowing your supplier, product, and its origination is as important as knowing the toxins in your food.  CBD is highly accessible,  and has proven to be a valuable source of health and wellness.  Unfortunately, the lax nature of laws around CBD production means that it’s not all safe, and that leaves us all vulnerable to tightening regulations in the US market.

    The way to avoid these pitfalls is to work with a processor who is cGMP by a stringent, globally accepted 3rd party auditor such as NSF. They should have current certificates available for both 111 & 117 (Supplements & Food). The FDA letter in May suggests that CBD guidance is coming and it will be regulated as a supplement.
