BAT Bets on Vaping as Tobacco Giants Battle With New Devices. Trailing Philip Morris International Inc. in the contest to move smoking alternatives beyond e-cigarettes is just fine with British American Tobacco Plc.

Fear or excitement causes signals to travel to the hypothalamus, which triggers a rapid heartbeat, faster breathing, widening of the pupils, and increased blood flow. The hypothalamus monitors blood glucose levels and the body's water content to regulate appetite for food or drink.
Adrenaline is one of the body's most important stress chemicals. It is secreted from the adrenal glands, which sit atop each kidney. Adrenaline also plays a key role as a neurotransmitter that facilitates communication between brain cells, or neurons, and other cells. An adrenaline rush is a sudden increased secretion of adrenaline from the adrenal glands. It causes an increase in heart rate and respiration. Adrenaline rushes can be healthy responses to actual threats to a person's well-being or symptoms of an underlying mental disorder.
