Total nitrogen and nicotine showed significant negative correlation with browning reaction. 158 Saliva tests for cotinine, which is made when nicotine is broken down by the body, were taken to determine if people had really given up. 159 In their study, the researchers tested blood for cotinine, a chemical which is produced when nicotine is metabolized, so they got an objective measure of how much smoke the teenagers were exposed to. 160 Figures aside, the pictures speak for themselves, showing that the danger of nicotine poisoning is real and that better regulation and monitoring is needed. 161 In the sidestream smoke of cigarette, there are many substances which are harmful to people's health, such as nicotine, aldehyde. 162 Other alkaloids include strychnine, nicotine, morphine, mescaline, and emetine (the deadly ingredient in hemlock). 163 In their new study, the scientists screened the entire human genome and teased out a profile of genes that they think are involved in breaking nicotine addiction. 164 For instance, one item might be: " Nicotine is an addictive drug.
