tceight started off with 20g of tobacco and then had this to say...
"- assuming there is 200mg of alkaloids in the oil, you would add 10ml of PG to get 20mg/ml.
This stuff is way stronger than any nic juice i've tried, so I kept adding 10ml at a time, until I had 40ml. (5mg/ml assuming)
So, either I am way off in my guestimates of extraction efficiency, or the WTA is Very synergistic.
- next batch, I will just add the 40ml of pg to the 25ml of oil all at once and simplify this step further."
If that's answers your question.
