Doesn't work that way. For one, cigarettes are pretty pernicious. They lend themselves pretty readily to certain rituals, and all smokers develop them. The rituals themselves are rewards, so that once the sequence is started, it tends to go to completion. Smokers often wind up with a cigarette in their hand and no idea how it got there. So, when stressed, they will automatically start the sequence and are smoking before they know it. Which is why it is such a hard habit to break. I did some work for a company that produced supplements to help break the addiction by providing a mix of amino acids to help produce serotonin, which is the neurotransmitter released by nicotine. I read a lot of papers on the subject of addictions, it was very interesting. Anyway, the cigarettes themselves are a potent source of serotonin release, just the nicotine isn't going to satisfy it. The higher nicotine would make it that much more difficult to quit. "And that's assuming that the report is accurate, and that the change is deliberate." Assuming the report is accurate, and that definitely is up in the air, the change is deliberate. It cannot happen by accident because nicotine level is one of several parameters that the manufacturers carefully control. In fact, most of the nicotine is extracted as part of the processing and then gets added back in later in the cycle. Nicotine is also extracted from the stems and discarded parts, so they make sure they have enough to bring the cigarettes all to a uniform level of nicotine.
