Drugs are chemicals that can change the way a persons body works.
Stimulant Speeds up the heart Normal HR Normal HR Racing HR Racing HR Depressant Slows down the heart Slows down brain function Slowed down HR Slowed down HR Hallucinogen can alter all senses illusion of things that aren’t real
Inject---needle Ingest---eat it Inhale---gas form Snort---powder form
There are approximately 4,000 chemicals in a single cigarette There are approximately 10,000 chemicals in a single cigar So, which one is worse?Cigarettes! At least 56 of these chemicals are known to be carcinogenic. Carcinogens – chemicals that are known to cause cancer.
Where did these carcinogens come from? What is second hand smoke? Pesticides – bug spray Second hand smoke has: 2 x the nicotine 5 x the carbon monoxide 98 x the ammonia 3 x the benzopyrene as mainstream smoke. Environmental tobacco smoke kills 53,000 people annually or 124 people each day – remember, these are non-smokers.
What is the addictive ingredient? An injection of one drop (70mg) will kill an average size man within a few minutes. Nicotine – currently the most addictive substance that humans are aware of. Nicotine in plants acts as a natural anti-herbivore chemical that discourages insects from eating the plant. Nicotine is pale yellow in color and is oily in consistency. Upon contact with air nicotine turns brown and is extremely poisonous in high concentrations. Nicotine acts as a stimulant when ingested by mammals and this is the reason why many people have a dependence on it.
98% of smokers will be lifetime users. About 2% will ever be able to quit for good. 12% of people get addicted on first time use. Each marijuana joint equals 4 – 7 cigarettes. =
Alcohol Name the 4 most common gate-way drugs: drugs that lead to other poor choices. Marijuana Inhalants Tobacco
Alcohol Arteriosclerosis: a hardening of the arteries. It is also a major cause of heart attack and stroke. Four main things that lead to arteriosclerosis: Tobacco Lack of exercise Fatty foods, poor nutrition
Stroke: lack of blood flow to the brain, due to a blockage in a blood vessel or the bursting of a blood vessel. Heart Attack: caused when the heart is damaged by a sudden lack of blood flow to the heart muscle.
emphysema: When you breathe, air is drawn in through the bronchial passages and down into the increasingly fine network of tubing in the lungs called the alveoli, which are many thousands of tiny sacs surrounded by capillaries. These absorb the oxygen and transfer it into the blood. When toxins such as smoke are breathed into the lungs, the particles are trapped by the hairs and cannot be exhaled. Instead, they remain in the lungs, clogging up the oxygen exchange mechanism and severely restricting the airflow. This damage causes the symptoms of emphysema.oxygenblood Emphysema is an irreversible degenerative condition. It is treated by supporting the breathing with bronchodilators and steroid medication, and supplemental oxygen is often required.
Your body (immune system) has 3 major lines of defense: 1. SKIN: as long as your skin is intact, your risk of infection is relatively non-existent. 2. MUCUS MEMBRANES: this is why your eyes water, nose runs, etc., when you get sick. It’s your body’s way of trying to keep your system free of germs. 3. FEVER: when something gets past your skin and mucus membranes you run a fever. Cilia is part of the 2 nd line of defense. These tiny, hair-like fibers are constantly sweeping debris up and out of your system.(eyelashes, etc)
Your body (immune system) has 3 major lines of defense: Cilia is part of the 2 nd line of defense. These tiny, hair-like fibers are constantly sweeping debris up and out of your system.
Your body (immune system) has 3 major lines of defense: TAR causes significant problems for cilia. It temporarily paralyzes it.
Your body (immune system) has 3 major lines of defense: Because the cilia can no longer function effectively, mucus that would normally be expelled is now pooling in the lungs.
Someone who smokes a pack-a-day for a year, has generated 4 cups of TAR. 1/3 of that stays in the tobacco filter 1/3 goes into the lungs of the smoker 1/3 goes into the air as second hand smoke Someone who smokes a pack a day for a year, has to clear about 2 cups of mucus out of their lungs every morning.
