Unfortunately these are all too common, and it worries us as much as it should worry you.
PhytoVista Laboratories, a UK market leader in CBD testing, has completed an independent blind test of consumer cannabidiol (CBD) products for The Centre for Medicinal Cannabis involving 30 major retail CBD oil brands.
The biggest issues related to accuracy of labelling; the presence of controlled substances and some contaminants; and in one example from a high street pharmacy, the complete absence of any cannabinoids.
- Only 11/29 (38%) of the products were within 10% of the advertised CBD content and 11/29 products (38%) actually had less than 50% of the advertised CBD content. One product had 0% CBD.
- Almost half (45%) of the selected products had measurable levels of THC (mean content 0.04%) or CBN (mean content 0.01%) and are thus technically illegal within the UK.
- One sample had ZERO cannabinoid content – this was a High Street pharmacy product (30ml) retailing for £90.
- One product had 3.8% ethanol (3.4% qualifies as an alcoholic beverage).
- Dichoromethane was detectable in seven products (3.8-13.1ppm) and cyclohexane was found in one product (27.9ppm). However, these percentages of solvents and heavy metals are still below the permitted daily dose levels in pharmaceutical products, although above food limit safety levels.
We take these issues seriously and strive with our partners to ensure the consumer can have confidence in our products, with independent laboratory testing to back our quality.
0% THC means there is non-detectability, indicating that the CBD in question contains less than 0.01% THC. ULU goes further, we set our targets at less than 0.0005% THC.
When we say 5% or 20% CBD content, that is what we deliver, guaranteed.
