Caffeine and nicotine are two of the most commonly used mood-altering substances in the United States. Despite their wide availability, both substances can cause unwanted side effects when taken individually or combined. Learning about the individual effects of tea and nicotine can help you prevent adverse interactions. Ask your doctor before consuming tea or nicotine if you suffer from a chronic health condition such as heart disease or high blood pressure.
Nicotine Side Effects
Nicotine is a substance found in tobacco and some smoking-cessation products. It is extremely addictive and produces withdrawal symptoms upon cessation. The National Institute on Drug Abuse lists sleep disturbances, irritability, increased appetite and strong tobacco cravings as symptoms of nicotine withdrawal. The substance acts directly on the brain to produce its effects, which include feelings of relaxation and satiety. Dry mouth, abnormal dreams, sweating, nervousness and muscle pain also are common side effects of nicotine.
Caffeine Side Effects
Like nicotine, caffeine is a stimulant that speeds heart rate and other functions. Tea made from the Camellia sinensis plant is a natural source of caffeine. Caffeine's side effects are dose-dependent and can occur when consuming any form of the substance, including tea. Symptoms of overstimulation, such as nervousness and insomnia, are common side effects. For some people, caffeine can even cause panic attacks or worsen the symptoms of premenstrual syndrome. If you're sensitive to caffeine, small doses like those in tea may be sufficient to trigger unpleasant effects.
Interactions
Tea and nicotine are often used together with few or no adverse effects. While the combination is not acutely dangerous for most people, it can cause problems for those with high blood pressure or other cardiovascular conditions. Because nicotine and caffeine are both stimulants, their additive effects may put unnecessary strain on the cardiovascular system by speeding heart rate and constricting blood vessels. Combining tea and nicotine in large amounts may also cause negative neurological or mood-related symptoms, because both substances act directly on the brain to produce their effects.
Application
The best way to completely avoid the risk of interactions between tea and nicotine is to use them separately or not at all. If you suffer from a cardiovascular condition such as high blood pressure, talk to your doctor about the safety of combining tea and nicotine. Replacing black tea with lower-caffeine varieties such as green or white tea can help reduce your daily caffeine consumption. If you use tobacco or smoking-cessation products, you may want to monitor your daily caffeine intake from all sources, such as medications and foods.
