Alcohol 101

Before you decide to drink it’s important to make sure you know the basics.

Factors that affect absorption

[spoiler title=”Food” style=”fancy” icon=”chevron-circle”]Contrary to popular belief, food does not “soak up” or “absorb” alcohol but instead, slows it down by coating the lining of your stomach. Essentially it’s a pay me now or pay me later situation where alcohol is absorbed eventually. Foods that are high in protein such as meats and nuts are more effective in slowing the process. [/spoiler] [spoiler title=”Gender” style=”fancy” icon=”chevron-circle”]Unfortunately ladies, there are some disadvantages to being a woman when it comes to drinking alcohol. Foremost, women have less of the fancy enzyme called alcohol dehydrogenase which breaks down alcohol. In this case, less is definitely more – intoxicated that is. Below are some helpful Blood Alcohol Concentration Charts for both men and women^*. This isn’t an exact science so please don’t present this to a police officer to argue your case…

[/spoiler] [spoiler title=”Alcohol content” style=”fancy” icon=”chevron-circle”]Seems to be common sense but you’d be surprised at how complicated it is. More alcohol in your drink = higher BAC. But, many drinks often exceed the “standard” amount of alcohol so long story short – 1 glass ≠ 1 drink. To get a periodic table version of alcohol content of most drinks click here. [/spoiler][spoiler title=”Drinking Rate” style=”fancy” icon=”chevron-circle”]The quicker you put it in the faster the effects right? Well, it’s more complicated than that. Chugging beer, shots etc., does not get you drunk immediately because your body still needs time to absorb the alcohol but when it does hit you it hits you ALL at once = intoxicated faster. By putting large amounts of alcohol into your body at once you don’t allow your body a chance to get rid of anything so it’s all happening at once. But you knew that already didn’t you? Water pong anyone? [/spoiler] [spoiler title=”Time spent drinking” style=”fancy” icon=”chevron-circle”]The longer you spend drinking the more intoxicated you’ll be IF you don’t allow your body to eliminate the alcohol. Translation: If you pace yourself to about 1 drink per hour, theoretically speaking you should be able to keep your BAC relatively low – granted, if you drink for 10 hours, not so much. Point: What’s the rush? [/spoiler]

 

Common Alcohol Myths

[spoiler title=”Drinking lots of coffee/water will sober you up” style=”fancy” icon=”chevron-circle”]Truth of the matter is nothing sobers you up other than time. Your body eliminates 90% of alcohol through your liver, the remaining 10% through sweat and urine at .015% an hour. To give you an idea:

If a 160 lb. man drinks around 5 drinks in 1 hour his BAC ≈ .14. At an average elimination rate of .015, it would take him roughly 4 hours just to be at .08! It would take an additional 5 1/2 hours to get rid of all the rest of the alcohol in his system!

Does this mean you should go run laps? No. Well yes from a health stand point but if you’re intoxicated I’d still say no. Water does help keep you hydrated so switching out alcoholic drinks with water is a great idea but water does not cancel out alcohol thus does not act as sobering agent. [/spoiler] [spoiler title=”High tolerance = safe to drive” style=”fancy” icon=”chevron-circle”]The idea behind this is that a person with high tolerance looks less intoxicated thus is safer to drive. WRONG! First: Tolerance = Need for more to achieve original effect^*. Translation: Drink more to feel the same effects as before. Problem: Just because you have learned how to manage the physical symptoms of intoxication (speech, walking, etc.) does not mean you are immune to how alcohol affects your higher level thinking – i.e. your judgement.

Also, toleranceDOES NOT impact your BAC. Quite the contrary – if two men of equal height/weight drank 7 drinks in 1 hour – both would have a BAC of ≈ .20 BUT one may look less intoxicated because he has a higher tolerance. [/spoiler] [spoiler title=”One drink can’t impair my driving ability” style=”fancy” icon=”chevron-circle”]Think again – Research shows that driving ability can be impacted at BAC’s as low as .02 in which judgement is already being affected^*. Men weighing around 140-150 lbs can easily reach .02 from 1 drink. For women weighing 100-120 pounds, 1 standard drink can result in a BAC of .04-.05! Research has shown that BAC’s of .05 can impact a person’s eye muscle control and vision thus, their ability to drive. Don’t take a chance – always designated a DUDE. [/spoiler] [spoiler title=”Someone isn’t drunk until they look drunk” style=”fancy” icon=”chevron-circle”]One of the big problems with telling if a person is intoxicated or not is that we always wait for visual cues like stumbling, slurring, dropping things etc., to decide if a person’s had too much. The problem is that research shows many people don’t start to show these visual cues until BAC’s past the legal limit of .08^*! The safest way to tell is someone is past their limit is to count their drinks! Regardless of what a person may say, the number of drinks speaks for itself and you should never allow them to drive![/spoiler]
