Before you ask, yes, I do plan on keeping my promise to quit smoking by year's end. I know I'm running out of time and I haven't taken step one toward putting down the cancer sticks, but my intention remains. So no need to email me the link to this story:
The team found that men with higher scores on the lifetime alcohol problems scale (LAPS) and those who reported a higher number of pack-years of smoking (i.e. packs of cigarettes smoked per day times number of years) both had lower IQ scores and lower scores on a test of global proficiency.
At least I've taken care of the alcohol problem thing.
