6 things I didn't know about weed and my brain
Last updated: November 2, 2026
Summary: I assumed the research on cannabis and the brain was simple. It isn't. Here's what I found when I actually read it, and what I changed.
Here are all 6 👇
PART 1
What the research actually says
1. It depends on when you started
For years I assumed the story was simple. The newer studies say otherwise. People who started before 16 have been linked to more errors on attention tasks than people who started later.1 How much and how long matter too: in a group followed from birth to 45, long-term heavy use was associated with poorer memory and processing speed by midlife.2
2. Working memory is the one to watch
63%
of heavy lifetime users showed lower brain activity during working-memory tasks, in the largest brain-imaging study of its kind (1,003 adults aged 22 to 36).3
Working memory is holding something in mind while you use it: following a meeting, juggling tabs, remembering what you walked into the room for.
3. The picture is more mixed than I expected
Large studies of middle-aged and older adults haven't found the long-term picture most people assume.4 That isn't a free pass, and it isn't a reason to panic. It's a reason to treat brain health as a long game.

PART 2
Brain health is a long game
4. Focus you can feel on day one
Neuroprotection pairs 100 mg of caffeine with 100 mg of L-theanine, a combination studied for focused attention and accuracy.5* Prefer to skip caffeine? There's a caffeine-free version.
5. Memory is the slower build
Bacopa (300 mg, 20% bacosides) is studied for memory and speed of attention, including a meta-analysis of 9 trials and 437 people.6 PQQ (20 mg) is studied for memory and mitochondrial energy, including a 12-week trial at the same dose in adults aged 41 to 65.7* This part takes weeks of daily use, not days.
6. Check the dose, not just the ingredient
Plenty of brain supplements list ingredients without amounts. Neuroprotection prints every one:

300 mg
Turmeric, 60% curcuminoids
