Alcohol Wins

I’ve heard the argument too many times to count: alcohol’s worse for your brain than weed. It’s not like anyone’s disputing it. But there’s always this gap between what we know and what actually gets legalized, and that’s where Germany’s been stuck—where most places have been stuck, really. The cops know it. The researchers know it. The law still doesn’t care.

A study from University of Colorado Boulder finally put the data in front of everyone. 853 adult brain scans, 439 from teenagers. They compared what alcohol does to your brain against cannabis. The difference isn’t subtle. Alcohol shrinks your gray matter and your white matter. Gray matter’s where you actually think. White matter’s how your neurons talk to each other. Cannabis doesn’t do that. It doesn’t sit there reducing the volume of your brain the way alcohol does.

Kent Hutchison was one of the researchers. He said something that stuck: We’ve known for decades that alcohol is bad for the brain. The weird part is how the cannabis research keeps contradicting itself—one study says it shrinks the hippocampus, the next one finds changes in the cerebellum, the one after that finds nothing. But alcohol? It’s consistent. Measurable. The studies don’t have to fight with each other because every piece of evidence points the same direction.

The obvious conclusion is sitting right there: if you’re choosing between getting high and getting drunk, you’re choosing the option that doesn’t physically shrink your brain. But there’s always that careful German qualification in the research—long-term cannabis effects still need more study, so don’t think you should smoke all day. Fair point. Moderation’s still the thing nobody wants to hear.

What gets to me is how far the policy lags behind the science. André Schulz, who runs the German criminal police, has said out loud that cannabis prohibition is arbitrary and hasn’t worked. The people whose job it is to deal with the actual fallout think it’s a failed experiment. Alcohol—legal everywhere, normalized completely—does more damage. And somehow the argument keeps going. That’s the absurdity.
