Tobacco is one of the most widely-used drugs. Once smoked, the nicotine in the tobacco reaches the brain in a few seconds, stimulating a release of the neurotransmitter dopamine, which makes you feel less anxious, more mentally alert and mildly euphoric. That’s the good news.
The bad news is that nicotine is powerfully addictive, meaning that for many smokers, the reason they smoke is not to experience these positive effects but to satisfy an addiction that can be very difficult to overcome.
And the health risks faced by people who smoke are well-known: high blood pressure, cardiovascular disease, emphysema and lung cancer, to name a few.
