Notes

ACE touchscreen question "About how many cigarettes did you smoke on average each day?"

The following checks were performed:

If answer < 1 then rejected
If answer > 150 then rejected
If answer > 100 then participant asked to confirm

If the participant activated the Help button they were shown the message:

Count the total number of cigarettes (including both hand-rolled
and manufactured cigarettes if both were smoked)
For hand-rolled cigarettes:
- One ounce of tobacco makes about 30 cigarettes
- One gram of tobacco makes about 1 cigarette

Field 6183 was collected from participants who indicated they currently smoke cigars and pipes, as defined by their answers to Field 3446 and previously smoked cigarettes on most or all days, as defined by their answers to Field 3446

Coding 100353 defines 2 special values:

-10 represents "Less than one a day"
-1 represents "Do not know"
