Cigarettes
They are the number 1 cause of preventable disease and death worldwide. Smoking related diseases claim more 480,000 lives in America alone. Each year smoking costs the U.S. at $289,000,000,000 each year. In addition at least $150,000,000,000 in lost productivity and $130,000,000,000 in direct healthcare expenditures. That averages around $7,000 per adult smoker. Cigarettes contain more than 7,000 chemicals at least 69 of them are known to cause cancer. Among adults who have smoked daily 87% had their first by 18. 95% had their first by age 21. In 2015 an estimated 15.1% (36,500,000) of adults 18 or older were current smokers. Men are more likely to smoke than women. 16.7% men currently smoked compared to 13.6% of women. 21.9% of American Indians/Alaska Natives smoked. 16.6% of Non-Hispanic whites smoked. 16.8% of non-Hispanic blacks smoked. Lowest was among Hispanics at 10.1% and Asian-Americans at 7%. 9.3% of high school students were current cigarette users. 2.3% of middle school students were current cigarette users. Some chemicals or substances in cigarettes known to cause cancer: Nicotine-derived nitrosamine ketone, Nitrosonornicotine, Formaldehyde, Acetaldehyde, Benzo(a)pyrene, Benzene, Polycyclic aromatic hydrocarbon, Aminobiphenyl, Naphthylamine, Butadine.

Marijuana
Marijuana 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.
