Cannabis temporarily disrupts your brain's notepad, making you forgetful.

There is a part of your brain shaped like a banana called the hippocampus. Think of it as your brain's sticky-note pad. It holds onto short-term memories before writing them down in your permanent memory book. This area is packed with locks that THC fits into. When THC attaches to them, it pauses the notepad. This is why people on cannabis might forget what they were saying mid-sentence, or find it hard to learn new information while high.
