Quick thoughts, have to run cuz have a doc appt. but, in no particular order:
My XWH is an alcoholic. He hasn't had a drink in 38 yrs. but he's still an alcoholic and if he had a drink today, his body would respond as though he's still been drinking for the last 38 yrs. and he'd be down for the count in no time because he was very bad at the end of his drinking days. He went through a treatment facility for 30 days, I went into intensive AlAnon and an unaffiliated study group. How I wish I'd kept that up but I digress.....
My father was an alcoholic as well. And my son is but sporadically, more what we call a binge drinker. My DD might be or it might just be that she likes alcoholic men and drinks with them. I am not. Not even close. I don't like to drink and I don't like to feel buzzed.
There's a reason I say that. I wouldn't be any good at my need to control if I wasn't 100% completely sober. That's MY lifelong addiction and I do whatever I have to do to keep that part of me sharp and hypervigilant.
Anyway, all 3 of them are completely different types of drunks. But they didn't become alcoholics because they drank too much, they drank too much because they're alcoholics. The person having 2 drinks a day no matter what is definitely an alcoholic (addicted).
Just like people smoke because it makes them feel better, more human, more alive, sharper in their mind, whatever, that's what they're looking for when they have those 2 drinks. People don't drink to get drunk on a regular basis until they are way far down into addiction and it's not that they want to feel drunk, they want to feel normal but once they're that far along (with the way their bodies process it), they need more and more alcohol to get that good feeling and so they end up drunker than drunk.
(Alcohol has a half life. Will explain further if you like or you can google it).
It is not a moral failing and talking to one about it that way is insulting to them. It's like a diabetic - something inside them doesn't process alcohol like a normal person's system does. Shaming fat people has never worked and has been shown to make it worse; the fact is, their bodies process the food differently than a naturally thin person's does. I'm not saying they have an excuse but they have a reason and when a person has a reason, it is their duty to find out what to do about their situation to make themselves the best that they can be.
AlAnon is for the friends and family of alcoholics.
I don't think weed is addictive? I went to college in the 60's and all of my friends smoked it and none of them are addicted. They also drank like fish in college but just my XWH and one other guy became alcoholics. XWH and the other guy (who I'm still dear friends with) both came from alcoholic backgrounds. It's genetic.
My uncle drank 2 martinis every single day of his adult life. No more, no less. 2 of his brothers died of alcoholism; my Dad went into treatment at age 66 and lived to age 88 but he did suffer from dementia those last 20 years, probably because of the alcohol abuse. The other brother didn't drink at all because he'd watched his father and all his brothers suffer so much from it. Funny story: he did drink some wine at a retiree Christmas dinner when he was 89 and passed out right there at the table (he thought it was grape juice; his bod knew otherwise!). All 6 of those men were alcoholics because their father was. They all responded to the circumstances differently. But they all had to deal with it.
My hobby is genealogy and I've gotten very interested in the dna testing. I read the other day that after studying the dna tests of thousands of self-admitted alcoholics, the scientists believe maybe there was a virus back thousands of years ago that caused a mutation that leads to addiction. But there was something they could see that the alcoholics had different than non-alcoholics.
I hope this helps. Tell you friend to go to AlAnon or read it online or attend an online meeting or listen to the podcasts. Helpful philosophy no matter what's going on in your life. Basically tells you to take care of you and quit trying to control other people.
Gotta run - sorry it's jumpy and poor grammar. Maybe will fix later.
