Product Manufacturer Details

All Professor Herb products are manufactured in the UK, by or on behalf of Organic Products Distribution Group Limited (Unit 73, Leicester, LE7 3XD, United Kingdom).

Our products are batch tested to ensure the THC levels are less than 0.2% and less than 1 milligram of THC per pack. In most cases, our products contain lower than the limit of quantification of Delta-9 Tetrahydrocannabinol (THC) concentration on a dry-weight basis, meaning that the content is almost zero.
