Simply stated, I just wanted to know what the average levels of thc tend to be for someone who is a heavy user at the time of consumption, with no specific answers just an estimation. 300 ng/ml, 400 ng/ml, 500, more? Like if I were to smoke right now and then tested myself, what levels could I expect is what I'm trying to get an idea of is all...
Simply stated, you are asking the impossible. There are too many variables to factor in to arrive at an estimation. Thare are no "average levels" to determine because of the variables.

Theres no way to determine your levels by using a home test kits anyway. Assays lack the ability to issue quantitative values.
To obtain quantitative values, the sample would have to undergo GC/MS testing.
