Hey, it happens in younger users.
I learned this fact:

Teenage users take two months until they stop showing signs of marijuana use.
beachguy in thongs Reviewed by beachguy in thongs on . Brain Chemicals:: Hey whats up smokers I gotta question. I went to a doctor to get an allergy shot (Real bad with grass and trees and I know it has nothing to do with cannabis lol) Anyways me and the doctor was talking for a bit before he on to the next patient. He told me that after you stop smoking cannabis it take a good couple of months to almost a year for the chemicals in the brain to settle back to normal.. Is this true? I was actually told that by two doctors, one phsychraist in a walking clinic. Rating: 5
