Understanding How Alcohol Addiction Works

We’ve all heard the addictive properties of cigarettes. We’re told not to have a single one – they’re as addictive as heroine! Well, what about alcohol? What causes us to become addicted, and will simply drinking more lead us toward addiction?

Let’s start with alcohol tolerance. It’s true that the more we drink, the more we can drink, and then the more we have to drink in order to feel the euphoric effects of alcohol. This is due to an enzyme known as dehydrogenase, the MVP in our bodies’ fight to become more tolerant of alcohol. Dehydrogenase hastens the filtration of alcohol from the body and increases in response to more constant heavy drinking, enabling more regular drinkers to power through that first six-pack without batting a lash.

Alcohol also causes the secretion of dopamine, which affects the brain’s ability to experience pleasure and pain. When moderate drinkers consume alcohol they typically feel a slight increase of dopamine in their systems, and a complementary increase in emotional intensity that only subsides once they start to sober up.

The problem for chronic drinkers (and those on their way) is that as dopamine levels continue to increase with consumption, their bodies also develop more “transporters” that facilitate quicker absorption of dopamine. The increased amount of transporters remains constant after binging so that when the heavy boozer’s binge is over and his body begins producing normal levels of dopamine, less dopamine remains in the system due to its faster absorption. This leads to depression and a craving to drink more in order to bring dopamine up to “natural” levels. Thus, addiction to alcohol has occurred.

Compulsion to keep drinking doesn’t stop at dopamine. Withdrawal from alcohol is rated at the severest level among popular legal and illegal drugs. Once addiction sets in, it not only becomes biologically harder to stop, but more physically painful as well, coaxing the addict to continue drinking.

It should be noted there are a variety of other factors that affect one’s likelihood of alcohol addiction including genetic predispositions, gender and ethnicity; however, due to the fact that 28% of all Americans drink at levels that put them at risk for addiction, no one should feel exempt from taking a closer look at their consumption habits.

Because everyone is different, you should work with your medical professional to determine what’s best for you. If you’re going to drink, do it legally and responsibly; don’t be stupid =).

    Great play list. I need to make myself one so I can use it to work out. The faster and the more dance partyish, the longer I can work out!

    – I have yet to visit! Hope the family is doing well. By the way, your audio on this page sounds weird. It sounds like it’s being played twice or something well, congrats!

    BAH! What bothers me most is that no one even noticed this. It's OK to make a mistake, but not OK for those who are in charge of your baby all day to not be paying attention to her. I thought you were going to say you went into the school and let it fly! Did you??

    Hi DimitriNo offence intended towards you, but definitely towards the author of "Sexy Combo".This is a rip off of the Ext.ComboBox.Some of the property names, and even the image used is a direct copy.The author managed to mess up some of the CSS, and hasn't managed to hook up the image to handle the mouse-over, when-button-pressed functionality.The author hasn't even had the decency to acknowledge Ext JS on his web-site.

    Hm. I think what’s being described here is what’s going on with this woman, Martha, who blogged about an addictive cycle she gets into after drinking alcohol:
