The consequences of smoking seen through a daphnia

As part of the CED+ programme, students took part in biology experiments to test the changing heart rate of daphnia. The experiment required students to place a variety of addictive substances including nicotine and alcohol in the daphnia’s environment to compare their heart rate before and after the addictive substance.

The results of the daphnia experiement can be seen to the right.

The results show the effects of a stimulant drug (tobacco) and a depressant dug (alcohol) on the daphnia’s heartbeat. It is clear the depressants reduce the heart rate whilst stimulants increase heart rate.

Addiction is the principle of having a compulsive need for an object or a practice. For example smokers are addicted to cigarettes.

Smoking is an addictive habit because the stimuant drug known as nicotine makes the brain release endorphins that provide a feeling of pleasure. This feeling goes away in time, making a smoker crave more nicotine to bring that same feeling back.

Why do you get addicted? Researching in the science lab

Many smokers gets addicted to their cigarettes, but why? This question is being answered underneath and the truth is that it is all combined with the chemical called ‘dopamine’.

What is dopamine
Dopamine is like chemicals in your brain, it’s the feeling people gets when they achieve a goal, it’s the feeling you get when you finally beat the boss in a game, when your dad rubs your shoulder and says “well done”.
Dopamine is like a drug there gets realized in the brain when you do such things, our line here is that there are many ways to get this feeling/dopamine.

Outside the central never system, dopamine functions primarily as a local chemical messenger. In blood vessels, neurotransmitter in the brain release and acts of blood vessels the kidneys, it increases sodium excretion and urine output; in the pancreas, it reduces insulin production, in the digestive system and in the immune system and it reduces the activity of white blood cells. With the exception of the blood vessels, dopamine in each of these peripheral systems is synthesized locally and exerts its effects near the cells that release it.

All drugs of abuse excite the parts of the brain that make you feel good. But, after you take a drug for a while, the feel-good parts of your brain get used to it. Then you need to take more of the drug to get the same good feeling. Soon, your brain and body must have the drug to just feel normal. You feel sick and awful without the drug. You no longer have the good feelings that you had when you first used the drug.

After you take a drug for a while, the feel-good parts of your brain get used to it. Soon, your brain and body must have the drug to just feel normal.

E cigarettes

Electronic cigarettes (also called e-cigarettes or electronic nicotine delivery systems) are battery-operated devices designed to deliver nicotine with flavorings and other chemicals to users in vapor instead of smoke. While e-cigarettes are often promoted as safer alternatives to traditional cigarettes, which deliver nicotine by burning tobacco, little is actually known yet about the health risks of using these devices. Some people believe e-cigarette products may help smokers lower nicotine cravings while they are trying to discontinue their tobacco use. However, at this point it is unclear whether e-cigarettes may be effective as smoking-cessation aids. There is also the possibility that they could perpetuate the nicotine addiction and thus interfere with quitting.
