Researchers analyzed 30 people who consumed marijuana daily with individuals who did not smoke it, for 4 weeks. Through a molecular scanner, the researchers managed to see changes in the brain of the volunteers. They found that certain brain receptors of smokers had decreased by 20%, compared to the brains of non-smoking participants, or who had had some type of minor exposure throughout their lives.

"With this study, we are able to demonstrate for the first time that people who abuse the cannabis has abnormalities in some receptors of the brain "mentioned the author of the study, Dr. Jussi Hirvonen , in the newsletter of the Society of Nuclear Medicine.

In another experiment, it was re-analyzed at 14 chronic marijuana smokers after a month of abstinence of the drug, and he found a remarkable increase in the activity of the receivers in the areas that had been deficient in the previous study.
