During the same time period that cigarette smoking around children came down more than 7%, marijuana smoking around children went up nearly 5%. With more and more states legalizing marijuana for recreational use, that number is likely to continue going up.
This is not good. Besides the fact that we don’t want children getting high, or exposed to the dangers of inhaled secondhand marijuana smoke, there is the additional concern about long-term effects on the brain. While research is still ongoing, there is evidence to suggest that when youth and young adults (whose brains are still developing) are exposed to marijuana, it may have permanent effects on executive function [3], memory, and even IQ.
