The science is still, well, hazy—but some research is starting to give us an idea of what exactly weed does to the human body.

Many had abnormal blood levels in areas affected by Alzheimer's disease, such as the hippocampus.

The findings, published in the latest Journal of Alzheimer's Disease, are an ominous warning as the United States rapidly embraces recreational and medical marijuana legalization.

The patients - from California, Washington, Virginia, Georgia and New York - all had complex treatment-resistant issues, and all underwent single photon emission computed tomography (SPECT) - a sophisticated imaging study that evaluates blood flow and activity patterns while undergoing concentration tests. Comparing those patients' brain scans with 100 healthy controls, the researchers saw a stark difference in blood flow levels.

Every marijuana user had significantly lower blood flow in the right hippocampus compared to the controls.'As a physician who routinely sees marijuana users, what struck me was not only the global reduction in blood flow in the marijuana users brains , but that the hippocampus was the most affected region due to its role in memory and Alzheimer's disease,' she said.

Volunteers who were given marijuana with high THC content were not able to come up with as many solutions to a problem as those given a placebo.

All those jokes about stoners killing their brain cells?

"Some people may believe that marijuana is not addictive or that it's 'better' than other drugs that can cause dependence," Heitzeg said.

"But this study provides evidence that it's affecting the brain in a way that may make it more difficult to stop using it.

After rats inhaled secondhand smoke for one minute, their arteries carried blood less efficiently for at least 90 minutes.

When they were exposed to secondhand tobacco smoke, however, their blood vessels recovered after 30 minutes.

"While the effect is temporary for both cigarette and marijuana smoke, these temporary problems can turn into long-term problems if exposures occur often enough and may increase the chances of developing hardened and clogged arteries," said study author Matthew Springer, Ph. Smoking weed may increase your odds of getting testicular cancer, researchers at the University of Southern California found.
