A new study published in the Journal of Neuroscience explored why smoking marijuana creates a sense of paranoia. As opposed to going the “it’s just those silly chemicals” route, it was suggested that paranoia results from fear-based learning.
Think of it like this: say you got very sick the last time you drank tequila; the next time it’s offered to you, you experience nausea even if you don’t partake. You then avoid tequila for fear of becoming very sick again.
Apparently the paranoia response while using marijuana works in the same way. You’re paranoid of a certain place, a certain action, a certain object – not simply because you’ve toked up. So, if you’re afraid of your couch when you’re high, you most likely won’t remain so once you’re sober.
