If you really think about it, how many deaths were caused because of Marijuana? NONE! But with Alcohol and Tobacco: millions of deaths reported. I think it should be legalized. And that we should ban Alcohol and Tobacco. I mean Weed isn't all bad. I have never tried it, but I don't do all three that's for sure. haha But read it up on the internet, that Weed is harmless! Their research suggests that the development of a legal drug that contains certain properties similar to those in marijuana might help prevent or delay the onset of Alzheimer’s disease. Though the exact cause of Alzheimer’s remains unknown, chronic inflammation in the brain is believed to contribute to memory impairment.
Any new drug’s properties would resemble those of tetrahydrocannabinol, or THC, the main psychoactive substance in the cannabis plant, but would not share its high-producing effects. THC joins nicotine, alcohol and caffeine as agents that, in moderation, have shown some protection against inflammation in the brain that might translate to better memory late in life.
“It’s not that everything immoral is good for the brain. It’s just that there are some substances that millions of people for thousands of years have used in billions of doses, and we’re noticing there’s a little signal above all the noise,” said Gary Wenk, professor of psychology at Ohio State and principal investigator on the research.
Wenk’s work has already shown that a THC-like synthetic drug can improve memory in animals. Now his team is trying to find out exactly how it works in the brain.
The most recent research on rats indicates that at least three receptors in the brain are activated by the synthetic drug, which is similar to marijuana. These receptors are proteins within the brain’s endocannabinoid system, which is involved in memory as well as physiological processes associated with appetite, mood and pain response.
This research is also showing that receptors in this system can influence brain inflammation and the production of new neurons, or brain cells.
“When we’re young, we reproduce neurons and our memory works fine. When we age, the process slows down, so we have a decrease in new cell formation in normal aging. You need those cells to come back and help form new memories, and we found that this THC-like agent can influence creation of those cells,” said Yannick Marchalant, a study coauthor and research assistant professor of psychology at Ohio State.
Marchalant described the research in a poster presentation November 19 at the Society for Neuroscience meeting in Washington, D.C.
