Scientists have found the mechanism that causes forgetfulness when smoking marijuana.
Marijuana’s active ingredient, THC, acts on cannabinoid receptor neurons called CB1. While found in several locations within the brain, there are two concentrations of CB1-type cells in the hippocampus.
To explore how each of these neural networks might affect memory loss, the researchers created two groups of genetically modified mice, each missing the CB1 receptors in either of the two regions.
The rodents were then injected with doses of THC equivalent to “heavy use” of marijuana in humans.
One of the groups reacted in the well-known forgetful fashion when required to do memory tests.
The other mouse group — whose CB1 had been removed from the so-called GABAergic neurons — was unaffected by the drug.
OK, folks. I see a smear job coming from the anti-weed faction of the world's population. Fact is, marijuana is much safer than alcohol, and the only thing it does is..... um, it does.... hmmm.
Excuse me, what is the subject of this thread again?
