I will have to agree with poplar that it does more good
than bad.
I don't think most animals would have cannabinoid receptors
if weed was really that bad for you.
And yes, most animals do have cannabinoid receptors for those
that did not know.
But, to answer the question, for me, it really depends.
Most of the time (80%) I don't remember anything when
I'm baked. Its incredible how many times I can lose a lighter
when I'm takin hits from the bong. lmao.
Or how many times
I get up to do something, and half way down the hall way
I'm asking myself where the hell I am going and what was getting
ready to do.
But I have noticed when I'm studying high, if I really focus I
can remember everything even after I'm not high.
Thats only when I really concentrate though.
