Dua Lipa's husband, the guy most likely to be the next James Bond, smoked weed every single day from 18 to 26. He was working as an actor that entire time, booking real roles, and he still says he missed four years of his life. That sounds impossible until you learn how your brain keeps track of time. It figures out how long a year lasted by counting how many new memories you made in it. And THC goes straight for the part of your brain that makes them. That part is the hippocampus, which is basically where your day gets saved. It's packed with CB1 receptors, the exact thing THC latches onto. In rat studies, when researchers switched those receptors on, short-term memory fell apart in a way that looked a lot like what happens when the hippocampus gets removed. It gets worse at night. Your brain does a lot of its memory filing during REM sleep, and THC suppresses REM. That's why so many daily smokers say they stopped dreaming. When they quit, REM comes flooding back so hard that "disturbing dreams" are literally listed in the official medical definition of cannabis withdrawal. Then there's motivation. A 2014 brain imaging study out of London found regular users had a lower capacity to make dopamine, and the more they smoked, the lower it went. The people with less dopamine also scored higher on apathy. So you skip the new place, you don't call anybody back, you stay in, and tonight looks exactly like last night. Psychologist Claudia Hammond has a name for the other side of this. She calls it the holiday paradox. A week on vacation somewhere new feels huge when you look back, because it left you with a pile of fresh memories. A month of the same night on the same couch shrinks down to almost nothing. Researchers are still arguing over exactly how much memory drives it, but it's the best explanation anyone has for why some years feel like they never happened. Now listen to how Callum Turner put it. He said he never smoked on set, but as soon as he got home he was "a real addict." So the hours he spent working were the hours he was fully there for. Everything after he got home turned into the same evening, over and over, for years. When he finally looked back at that stretch of his twenties, there just wasn't much to look back on. The good news is your brain bounces back faster than you'd think. A 2012 NIH study found daily smokers had about 20% fewer of those CB1 receptors, and after roughly four weeks without weed, their levels were back to normal. Turner did quit. He married Dua Lipa this year, and last week he was reportedly in the final round of Bond screen tests. He told the Independent it took him about nine years to accept the four he lost.
