Dirty CBD: Dirty, Dangerous and Dozens of Them

Pesticides, Heavy Metals, Residual Solvents, Mycotoxins, Yeasts, Molds, E.Coli and Salmonella

Great care and expertise (and of course accurate testing) from the field to the final CBD formulation must be taken by farmer and processor alike to ensure a safe and efficacious CBD consumer experience.

Whether CBD is ingested, inhaled, or topically applied, the rigor or laxness (or dereliction or recklessness) of the standards of growing and processing of the hemp plant will determine whether your health will benefit from all the good cannabinoids and phytochemicals in the plant, or if you will be exposed to dangerous contaminants.

Even if the hemp biomass test results show very low levels of the “bad,” during extraction and refinement processes, contaminants can be concentrated in what goes in your body. Similarly, any contaminant in your CBD product will be made worse by smoking, dabbing or vaping.

The hemp plant is an “accumulator,” absorbing heavy metals from the soil, fertilizer, and water. In Chernobyl, hemp was proven as a phytoremedient by up-taking radioactive elements from the soil. The ugly punch line is that cadmium, arsenic, nickel, lead, mercury and other heavy metals accumulated in the hemp plant will be magnified in your CBD product if clean growing conditions are not verified.

Other contaminants found in hemp include highly-toxic pesticides. Imported hemp and suspect or unverifiable growing practices domestically can introduce known carcinogens into your CBD product. Sloppy or poor processing methods can leave any number of residual solvents in a CBD tincture, softgel or lotion. Harmful yeasts and molds, mycotoxins, and other microbial pathogens are capable of causing disease and even death if a processor doesn’t adequately test and reject such contaminated hemp biomass prior to processing.

How does your CBD processor ensure you are not exposed to any of these dangerous contaminants?

The saying “garbage in, garbage out” most definitely applies. PPM only sources biomass free of contaminants from registered hemp growers. PPM inspects fields and growing records.

A high-quality processing company’s adherence to cGMP, licensing, process controls, testing, testing, and more testing, a safety and quality-first company culture, and a trained group of employees tuned to the technical reasons for rigorous standards – all safeguard the final product’s integrity.

And top-notch processors like PPM also: (i) follow pharma-level QA/QC programs, (ii) utilize in-house analytical testing with HPLC and GC-MS instruments performed by professional lab technicians, (iii) employ bar-coded tracking systems for full traceability, (iv) enforce strict SOPs, and (v) confirm final product quality with third-party analytical testing.

For every pound of biomass that enters PPM’s processing facility to every kilo of finished product, PPM’s single focus is the production of the highest quality, contaminant-free CBD for use as safe ingredients by the leading CBD consumer products companies.
