Smoking a cigarette is not the only way to get these types of cancers. There is another way called secondhand smoke “environmental tobacco smoke”. This is when MarijuanaMarijuana refers to the dried leaves, flowers, stems, and seeds from the Cannabis sativa or Cannabis Indica plant. The plant contains the mind-altering chemical THC and other similar compounds. Marijuana is the most commonly used illicit drug in the United States. Its use is widespread among young people. In 2015, more than 11 million young adults ages 18 to 25 used marijuana in the past year.
According to the Monitoring the Future survey, rates of marijuana use among middle and high school students have dropped or leveled off in the past few years after several years of increase. However, the number of young people who believe regular marijuana use is risky is decreasing. People can mix marijuana in food such as brownies, cookies, or candy, or brew it as a tea. Marijuana also affects brain development. A study from new Zealand conducted in part by researchers at duke university showed that people who started smoking marijuana heavily in their teens and had an ongoing marijuana use disorder lost an average of 8 IQ points between ages 13 and 38. The lost mental abilities didn’t fully return in those who quit marijuana as adults.
Those who started smoking marijuana as adults didn’t show notable IQ declines. In another recent study on twins, those who used marijuana showed a significant decline in general knowledge and in verbal ability (equivalent to 4 IQ points) between the preteen years and early adulthood, but no predictable difference were found between twins when one used marijuana and the other didn’t. This suggests that the IQ decline in marijuana users may be caused by something other than marijuana, such as shared familial factors. NIDA’s Adolescent Brain Cognitive Development (ABCD) study, a major longitudinal study, is tracking a large sample of young Americans from late childhood to early adulthood to help clarify how and to what extent marijuana and other substances, alone and in combination, affect adolescent brain development.
