Boomers drink less because they’re geriatric. 

Millenials are getting older. Many are on anti depressant/anxiety medication. Alcohol is a depresaant, and leaves people feeling unwell and tired. So they drink less. 

Gen-Z don’t drink because they can’t afford it. 

And cuz weed is better. Source: me
Weed is definitely better than alcohol, but I noticed many Gen Z that are skipping vices all together, unless its nicotine and tobacco.
I doubt it. This is some “everyone’s quitting social media” nonsense, people don’t stop addictive things they can still afford.
As with any drug it depends on amount ingested. 1 drink a week is probably way better than bonging it all day, every week.

That’s not a helpful comparison, though. Casual weed use is better than casual alcohol use. Alcohol abuse is more widespread than weed abuse.

Of course if you compare the extreme for each substance results can vary, like drinking 10 cans of pop every day is worse than using an opioid once in a lifetime.

Exactly, it is amount. Too much water in one day can kill you. So saying alcohol is worse than weed with no context on amount is worthless sentence.

So saying alcohol is worse than weed with no context on amount is worthless sentence.

Only if you’re a bit obtuse. You can just prepend “alcohol is worse than weed“ with “(for me, considering a very average dose on each) because that’s what people mean

Many don’t realize that though. I have had this argument before, with people telling me smoking a joint daily is fine but a drink a week is not. Sure alcohol is a poison you have to filter, but good luck with lung cancer also
