i smoked every day and now that i havent in a month and a half i forget words like that. ill be in a sentence and then forget the word and it will take me sometimes 5 seconds to rember it. i also used to have trouble remembering things mostly when i was leaving somewhere i would say to myself rember this and then forget it and remember it when i just pulled out and drove down the street and have to come back to my house and get it. but in school i could always recall vocabulary and such very easily after only reading it once.
