mrdevious is right...your just permafried. If you smoke weed every day, your body never really goes back to "sober" beacuse of the amount of THC thats constiantly being added to your body and mind. The effects of one smoking session can last up to a day afterwards...thats not staying high, just a cloudy or spacy feeling that lasts for hours after your intial high is over. So all you have to do is just stop for a week or so, and you will feel your memory comming back and a true sober feeling again. I have smoked ever day solid for several months at a time before, my memory and everything got really bad, and I just had to stop for a few days to get back to baseline, and my memory became clear again. Also, if you're in college trying to get a degree and everything, mabey you shouldnt be smoking everyday? Try to smoke less often and you will find you mind will stay alot clearer. Sorry that was long, but I hope it helps.
