to what exactly the % refer to
THC.
Why don't you read the paper, there is some interesting stuff in there (anything with numbers in it ).
For example what happens if you double THC levels?
1. People stop smoking
2. Experienced smokers use a lot less
3. Beginning smokers use more (untill they get experienced)
So "cannabis preparations" are enjoyed responsibly, unlike many other drugs.
Here is the latest on THC levels (in Dutch, but the numbers are Arabic):
