In addition to physical effects, smoking can cause many problems with the brain and cognitive system. Chemicals in tobacco products can weaken blood vessels’ walls and restrict arteries. As a result, blood flow transporting essential nutrients and oxygen to the brain can be significantly reduced. That is why your memory and other cognitive functions would be affected. Studies have shown that smokers tend to be at a higher rich of many mental problems, like depression or anxiety. If left for an extended period, they will eventually cause many other health issues, especially when you get older. [7]
