Modern Canna is an industry leader in PAH testing for  cannabis and hemp materials. Small traces of contamination have been found in some cannabidiol (CBD) oil. This means much of the CBD products sold over the counter may not be as pure as originally claimed by the manufacturer. For manufacturers and  suppliers that provide core ingredients, extensive PAH testing should be performed in order to determine the purity and integrity of their products.

What Are PAHs?

First, it’s important to know what polycyclic aromatic hydrocarbons (PAH) are. This is a chemical that emits when certain substances are burned. This includes known hazardous and cancerous substances, such as landfill waste, oil, gas, plastics, lubricants, electronic circuits, rubber, and coal. PAHs are known for their mutagenic and carcinogenic effects.

There are over 100 types of chemical PAHs. Under the European Union, eight PAHs are known to be especially hazardous, and products cannot exceed a certain concentration threshold.

PAH testing determines the level of certain PAHs when the item under question is burned.

What Is PAH Testing?

Gas chromatography is one common method for PAH analysis. The process involves the use of a gas chromatograph (GC) instrument. Under this  procedure, a sample is placed in the instrument where it goes through a tube filled with a gas stream. This separates the sample into its smaller components, allowing each component to be analyzed for its organic and chemical makeup.

Any sample that demonstrates a sufficient level of volatility and thermal stability can undergo gas chromatography testing.


Small traces of PAHs have been found in leading CBD oil brands. According to the International Cannabis & Cannabinoids Institute (ICCI), 20 of 29 CBD oils from European brands tested below satisfactory levels after sufficient PAHs levels were detected.

The Department of Food Analysis and Nutrition at the University of Chemical Technology has joined forces with ICCI to classify PAH as a carcinogen.
