Your answer should be True as nicotine and carbon monoxide in cigarette smoke puts a huge strain on your body's blood vessels, leading to cardiovascular disease (heart disease). This is also why people die all of the time from cigarettes. Even if you just smoke 1 cigarette it takes your chances of heart disease and puts your chances even higher than it was. Smoking just 1 cigarette also reduces your life expectancy by 7-8 YEARS.
Hope this helps :)
