^^^^ O Relli? How long did you smoke for before?
I suppose there could be long lasting affects. For myself the appreciation came back quickly.
You really feel altered after 3.5 years? Did you use other drugs besides marijuana?
i did not use other drugs except occasionally. but i did smoke marijuana from virtually the moment i woke up to the moment i went to bed for a couple of years and i have used other drugs since quitting (although i was clean an entire year and the affects did not reverse). after being stoned for two years straight, my mind just never really returned to baseline. i had other problems from it too, like anxiety and panic attacks and those have improved with time but the perceptual changes have not gone away.
