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.
