The other thread's locked, but an interesting paper I read recently investigated the link between memory function in the hippocampus and weed - the green menace of modern society! The investigate used a synthetic cannabinoid called HU210 which is [Dr Evil Voice] 100 times stronger than regular weed, for the ultimate high. [/Dr Evil Off] Contary to popular belief, they found that the HU210 was accelerating neurogenesis in the hippocampus, as opposed to retarding it. :surprised And that the two controls were pretty much stationary. p.s. I also just discovered that my cup is the perfect size to size McVities digestives in. Great!
