What is a good amount of THC in a cartridge?
Check potency and purity - Most THC oil cartridges should contain anywhere from 70-90%. Anything above or below that range is likely cut with some type of filler, or overprocessed unsafely to reach such high levels of THC.
How much THC percentage is too much?
It's rare to see THC levels above 25%. Although it is far more common to see claims of 25-30% THC levels in pot. Usually, the very finest quality cannabis you will see is in the range 25%-30% THC. In the real world, any cannabis strain with over 20% THC should be considered very strong.
