From Science Daily:

Smoking is dumb: Young men who smoke have lower IQs, study finds: A study led by Prof. Mark Weiser of Tel Aviv University’s Department of Psychiatry and the Sheba Medical Center at Tel Hashomer Hospital has determined that young men who smoke are likely to have lower IQs than their non-smoking peers. Tracking 18- to 21-year-old men enlisted in the Israeli army in the largest ever study of its kind, he has been able to demonstrate an important connection between the number of cigarettes young males smoke and their IQ.

Hmmm…. I’ve always maintained to my daughters that anyone that starts smoking today, with all we know, is a moron. I’ve even gone out of my way at times to point to the teenagers out in front of the movie theater and exclaim as much. Now I have scientific proof to back me up.

Thankfully, they understood, and never started. Now, if we could only reach the rest of the impressionable youth.
