Why Does THC Vape Potency Vary So Much Between Products?

[Balletrist]

THC vape products can differ substantially in cannabinoid concentration, formulation, and serving size, which can make simple percentage comparisons misleading. What information should consumers understand before interpreting potency claims on a vape product?

Jumping in on this older post because this is a really important point. Since no one else has replied yet, I’ll just say that the biggest thing to look for is the total milligrams of THC per container, not the percentage. A 90% vape with only 0.5ml might actually give you less THC overall than a 70% one with a full gram. Always check the serving size and how many puffs the maker says are inside.

I personally find that transparent lab reports make a huge difference
For consistent, high-quality options, I get my thc vapes from a shop that clearly lists THC levels and lab results, so I know exactly what I am using
