Nicotine Use 

Nicotine contained in cigeretts, smokeless tobacco, vapes (etc.) is highly addictive. All forms of nicotine (including synthetic nicotine) is harmful and there is no safe level of exposure.Nicotine is absorbed into your bloodstream and goes to your adrenal glands just above your kidneys. The glands release adrenaline which increases your blood pressure, breathing, and heart rate. Adrenaline also gives you a lot of good feelings all at once.
