The two man substances being abused In our nation are nicotine and alcohol. How does nicotine addiction work? Basically, when you smoke your first cigarettes, when you aren’t addicted yet, you get a head-rush which Is caused bythe nicotine. In your brain there are nicotine receptors which aren’t used to the nicotine In a cigarette. Over time, the nicotine receptors get used to the amount of nicotine so they can cope with the nicotine. So when this nicotine stops being given to the receptors (when you give up smoking) they panic and cause you to feel unhappy and angry.

When you smoke, the nicotine receptors send out messages to other parts of the brain which release a drug called dopamine which makes you feel happy, satisfied, relaxed. When you try to quit, or when you ‘fancy a cigarette’ your dopamine levels are going down and you start to feel unhappy, aggressive, unsatisfied. Most smokers don’t know that they are addicted to nicotine until they try to stop smoking completely they Just think that they Like smoking. The answer to your question Is that you will have a moderate nicotine addiction, and quitting won’t be that hard.

The signs of a severe nicotine addiction are needing to smoke a cigarette every 2 hours, having one as soon as you wake In night). Nicotine increases the levels of the neurotransmitter dopamine in the brain, activating the pleasure pathways in the same way other addictive drugs do. After the effects (calmness, sense of well-being) disappear, the smoker craves more. Why is alcohol addictive? Basically because alcohol, like nicotine and heroin and other substances stimulates the reward response in your brain.

You have a drink, the brain rewards itself with a surge of chemicals and hormones that it really likes, and therefore the more you stimulate it, the more it wants. Some people are more susceptible than others in that their reward responses are stronger which is why some people will get addicted to things more easily than other people will. If you add to that a troubled background of some sort, then when the brain offers its reward response though making that person feels calmer and happier or more in control, hey are more likely than someone who is pretty happy.

Alcohol is made of ethanol, it is a depressant, your body becomes addictive to the depressant effects and you eventually need it to stop the shakes (delirium tremors) and the withdrawals of the depressant effects on the brain and body. For example, caffeine is a stimulant, and people become addicted to that and when having caffeine withdrawals one has headaches and other neurological effects. However, alcohol is a lot more dangerous because if you are a hardcore not only can you die from drinking, if you stop cold turkey you can have convulsions and die from withdrawals.

The “addictive substance” is ethanol. When you are pregnant, it is important that you watch what you put into your body. Consumption of illegal drugs is not safe for the unborn baby or for the mother.
