Not surprised really. Anyone who has at least smoked pot occasionally can relate to this. I've had my moments where I smoked a lot for a couple of days, but i can't go further than that. I don't know how you guys go on smoking days on end, but i can last more than 3 days. That being said, I do find my short term memory a bit shitty after a couple of days, but give it some time, and it comes back to normal. I've had worse experiences with pharma drugs, such as Benzos. I swear, they give you the worst short term memory, than weed can possibly ever do.
