Short-term memory loss, long-term memory gain?

WASHINGTON, (Reuters) — Good news for aging hippies: Smoking pot may stave off Alzheimer’s disease.
New research shows that the active ingredient in marijuana may prevent the progression of the disease by preserving levels of an important neurotransmitter that allows the brain to function.
Researchers at the Scripps Research Institute in California found that marijuana’s active ingredient, delta-9-tetrahydrocannabinol, or THC, can prevent the neurotransmitter acetylcholine from breaking down more effectively than commercially marketed drugs.
THC is also more effective at blocking clumps of protein that can inhibit memory and cognition in Alzheimer’s patients, the researchers reported in the journal Molecular Pharmaceutics.

This is potentially huge news, for one very practical political reason: old people vote.
