A paper published by the British Journal of Pharmacology suggests that the chemical compounds in marijuana likely prevent the onset of Alzheimer's disease, Parkinson's disease, Huntington's disease, and age-related dementia.
Chronic brain inflammation, oxidative stress, and intra-cellular dysfunction are the primary reasons why people develop these debilitating neurological diseases. The study found that both THC and CBD (the primary chemical compounds found in marijuana) positively affect nerve cell function in consumers, significantly reducing these harmful neurological conditions.
THC and CBD (called cannabinoids) tap into a primal, chemical signaling system in cells called "the endocannabinoid system." The paper shows cannabinoids dampen inflammation, protect cells from oxidative damage, and promote cell health on a number of levels.
This paper echoes claims made in January by Gary Wenk, professor of neuroscience, immunology, and medical genetics at Ohio State University, that “if you do anything, such as smoke a bunch of marijuana in your 20s and 30s, you may wipe out all of the inflammation in your brain and then things start over again. And you simply die of old age before inflammation becomes an issue for you,”
The implications of marijuana’s medicinal effects on our brains are monumental, from not just a health perspective, but a financial one as well, for more than five million Americans with Alzheimer’s. One in three seniors will die with Alzheimer’s or another form of dementia, and Alzheimer’s is the sixth leading cause of death in the nation, costing the country about $203 billion in 2013.
