^^ the link cites an animal study that has no bearing on humans. Study about three years ago in Archives of General Psychiatry showed daily marijuana use to SHRINK the hippocampus (vital to memory) by about 16%. Other human data are equally discouraging concerning the effects of marijuana on memory, though one recent study suggests some possible benefit in PTSD symptoms.
