Smoking cigarettes is absolutely terrible for you. Countless studies show that it causes cancer, lung disorders, and heart disease. In fact, the World Health Organization (WHO) states that 1 in 10 adults, over five million, die from smoking annually. Furthermore, cigarettes have over 7,000 chemicals in them as well as up to 20 milligrams of tar per cigarette. Despite these grim figures, only about 7% of smokers quit smoking for good. Vaping cannabidiol (CBD), however, has shown promise in helping smokers overcome this terrible addiction.
Why Do People Smoke Cigarettes?
There is one fundamental reason why people smoke. They are addicted to nicotine. This is the primary active compound in tobacco and can result in both psychological and physical addiction. If you inhale a tobacco product, the smoke will absorb into your bloodstream and cross the blood-brain barrier within 7 to 10 seconds.
Once absorbed, nicotine has profound effects on the physiology of your body and brain chemistry, including:
- Releasing the hormone adrenaline, resulting in increased heart rate, high blood pressure, and vasoconstriction (decreased blood flow).
- Inhibiting the pancreas from releasing insulin, meaning that blood sugar levels stay elevated and appetite decreases.
- Activating nicotinic acetylcholine receptors (nAchRs) throughout the brain that govern respiration, memory, alertness, heart rate, and muscle control.
- Massively increasing dopamine l
