President Obama, you really should give those electronic cigarettes a try. I smoked for 45 years. The FDA-approved Nicotine Replacement Therapy (NRT) products didn't work for me. Using them as directed to wean totally off nicotine results in problems with mood, attention, and memory. The last thing we need is for the leader of our country to be afflicted with cognitive impairments.
Using NRT as a long-term maintenance therapy doesn't work for most smokers either, because the NRT products don't supply enough nicotine. The electronic cigarette is working as a complete replacement for smoking for up to 79% of users. The user can replace the required amount of nicotine to maintain normal mood and cognition. In user surveys, 90% report improved health.
So give it a try, Mr. President. All you've got to lose is your wheezing, coughing, and increased risks of other smoking-related diseases. I should know. I've been smoke-free since March 27, 2009 by switching to an electronic cigarette.
