E-Cigarette public smoking bans begin

Wednesday, August 19th, 2009

E-cigarettes have been declared illegal by the Food and Drug Administration [FDA], their sale has been banned in one state and several countries, PayPal has stopped facilitating their sale, Facebook has reportedly dropped their ads, and now one county was banned their use wherever conventional smoking is prohibited.

Other restrictions and problems are on their way for e-cigarettes, says public interest law professor John Banzhaf of Action on Smoking and Health (ASH), who has been behind many of these steps to protect the public from this untested product. A letter from ASH helped trigger this latest restriction, one which will prevent the use of e-cigarettes in any public areas and workplaces where the smoking of conventional tobacco products is now prohibited.

Too many espressos will make you see ghosts

Research suggests people who drink more than seven cups of instant coffee a day have an increased tendency to hallucinate.

High caffeine users may even think they sense non-existent people, according to researchers from the University of Durham. They studied 200 students who were asked about their typical intake of caffeine products. Those who had a high caffeine intake were three times more likely to have the heard voice of someone non-existent than “low” users who consumed less than one cup of instant coffee or its equivalent. Seeing things that were not there, hearing voices and sensing the presence of dead people were among the experiences reported.

Caffeine may stimulate cortisol

Besides coffee, caffeine can be obtained from sources such as tea, chocolate, “pep” pills and energy drinks. However, the hallucinations are not necessarily a sign of mental illness. Around 3% of people regularly hear voices, the research said. The ability of caffeine to exacerbate the effects of stress may be behind the study’s findings, scientists believe.

When under stress the body releases the hormone cortisol which is produced in greater quantities after consuming caffeine, possibly leading to hallucinations. Dr Charles Fernyhough, the co-author of the study, pointed out that the research only showed an association between caffeine intake and hallucination proneness, not a causal link. “One interpretation may be that those students who were more prone to hallucinations used caffeine to help cope with their experiences,” he said.
