Our Testing
Testing helps verify product quality and composition. NicoLeaks is maintained by Haypp and shares laboratory results for a range of nicotine pouch products in different markets.
This resource helps regulators, consumers, and researchers find objective product data in a consistent format.
● Haypp routinely tests nicotine pouches before listing them on site.
● Testing is performed by an independent, accredited laboratory.
● Nicotine pouch testing focuses on product composition, not health effects.
Why We Test Products
We want to empower our consumers with accurate information. We believe that providing testing results improves transparency and product understanding.
Testing does not determine whether a nicotine pouch is safe or risk free, but it does provide objective data about what a nicotine pouch contains.
The results are used as part of an internal review process to identify whether a product aligns with declared specifications and relevant market standards.
While we haven’t yet tested every nicotine pouch listed (although we are working on it!), we always test as part of our process when we are considering selling nicotine pouches from a new manufacturer.
After a product has been tested, the laboratory reports are published with a symbol and colour marking for the nicotine level (20 mg per pouch is our limit).
If a product is marked with a green shield with a checkmark, the value listed is within the recommended limit for nicotine per pouch.
If a product is marked with a red triangle with an X, the value listed exceeds 20 mg of nicotine per pouch and is not listed.
What Is Tested?
Multiple product characteristics, including:
● Nicotine Content
• The amount of nicotine per pouch is compared with the amount listed on the can (20 mg is our limit)
● pH Value
• pH affects product chemistry and consistency
● Selected Substances
• Trace metals
• Tobacco‑specific nitrosamines (TSNAs)
• Substances found in other tobacco products (but should not be in nicotine pouches)
• Other factors relevant to product quality (e.g. moisture)
Each report contains 26 unique results, corresponding to 23 measurements plus 3 sums. Here we break it down into 10 categories:
Test/Parameter
1) TSNAs (NAB, NAT, NNN, NNK)
2) Water content
3) Trace metals
4) Mycotoxins (mould-produced toxins)
5) Polycyclic aromatic hydrocarbons (PAH)
6) pH
7) Pouch weight
8) Microbial activity
9) Nicotine
10) Humectants
Why It’s Important
1) Carcinogenic tobacco-related compounds
2) Affects moisture and shelf life
3) Present in many foods but can be harmful at high levels
4) Carcinogenic, liver/kidney damage
5) Carcinogenic, environmental contaminant
6) Affects product chemistry and consistency
7) Used to calculate mg per pouch
8) Spoilage risk
9) Active ingredient
10) Affects moisture and shelf life
