The way it's worded:
"Our study shows that 15% of Ms. Johnsons 1am math class used a vape once in the last 30 days, out of those FIFTY percent used juul.
Out of those TWENTY FIVE PERCENT USE THEM 10 DAYS OR MORE"
Actual reality - 1 teen uses a juul a little too much.
Plus they didn't even use the usual "addiction" predictor of 20 or more days of use a month.
Some people use hard drugs 10 days or less a month and don't get addicted.
I still haven't seen actual proof of a never smoker getting addicted to any vaping device (or even NRT) yet.
They decided to use the data from 10 days a month probably because if they chose to go with 20 days a month it would have shown a REDUCTION in teenage vaping and then they would have had to explain the fake panic to everyone.
