Deaths Rise From Unintentional Drug and Alcohol Overdoses in the Workplace
Deaths from unintentional drug and alcohol overdoses in the workplace rose more than 30 percent in 2016, a new report concludes.
The effects of nicotine on the parts of the brain involved with addiction are similar to the effects of cocaine, according to a study using rat brain tissue. The study found that one 15-minute exposure to nicotine caused a long-term increase in the excitability of nerve cells involved in reward.
The researchers said this study, which indicates that nicotine and cocaine both affect the reward system of the brain, may help explain why so many people have a difficult time quitting smoking, and why so many people who experiment with cocaine end up becoming addicted.
