In 2016 the National Study on Drug Use and Health reported that an estimated 28.6 million Americans age 12 and over used illicit drugs during the month prior to the study. That means roughly 1 in 10 people struggle with some level of illegal substance use, including addiction to prescription drugs.
When you look at the vast numbers using drugs, the 70 - 80,000 that die each year from drugs doesn't sound so high. Thus, many using drugs feel the risk is worth it.
Nearly 1.25 million people die in road crashes each year, on average 3,287 deaths a day, yet no where in the world is there any indication people are avoiding auto travel. Thus, many travelers feel the risk is worth it.
In the U.S. over a million people die each year from smoking and obesity related diseases. Many Americans feel the risk is worth it. If you feel the risks are worth it, don't feel obligated to stop. Sure, your friends and family may wish you to live a healthier lifestyle, but if you just are not into it, don't do it.
