I am afraid smoking weed has negatively impaired my cognitive ability, irreversably. I started smoking around 17 or so, but I was never a stoner. Just an ocassional joint with my friend now and then. I continued smoking on and off up until now (21), but somewhere inbetween noticed that I don't get jokes anymore, I have to read certain things multiple times to get the meaning and such things.

I'm afraid this was due to weed and this I noticed a couple of years ago, around 19 or so. I'm not sure what to think of it but I'm pretty sure I fucking hate myself for it.
