Most drugs of abuse are addictive. Addiction is a chronic, relapsing disease characterized by compulsive drug seeking and use despite negative consequences and by long-lasting changes in the brain. People who are addicted have strong cravings for the drug, making it difficult to stop using. Most drugs alter a person’s thinking and judgment, which can increase the risk of injury or death from drugged driving or infectious diseases (., HIV/AIDS, hepatitis) from unsafe sexual practices or needle sharing. Drug use during pregnancy can lead to neonatal abstinence syndrome, a condition in which a baby can suffer from dependence and withdrawal symptoms after birth. Pregnancy-related issues are listed in the chart below for drugs where there is enough scientific evidence to connect the drug use to negative effects. However, most drugs could potentially harm an unborn baby.
The dangers of sleep deprivation are apparent on the road; the American Academy of Sleep Medicine (AASM) reports that one in every five serious motor vehicle injuries is related to driver fatigue, with 80,000 drivers falling asleep behind the wheel every day and 250,000 accidents every year related to sleep,  though the National Highway Traffic Safety Administration suggests the figure for traffic accidents may be closer to 100,000.  The AASM recommends pulling off the road and taking a 15- or 20-minute nap to alleviate drowsiness. 
Others purchase HGH products -- or products that claim to increase your body's own production of HGH -- in the form of pills and sprays. Companies that market these products on TV infomercials or online claim they turn back your body's biological clock, reducing fat, building muscle, restoring hair growth and color, strengthening the immune system, normalizing blood sugar , increasing energy and improving sex life, sleep quality, vision , and memory. However, the Federal Trade Commission has seen no reliable evidence to support the claim that these products have the same effects as prescription HGH, which is always given by injection. Taken orally, HGH is digested by the stomach before it can be absorbed into the body.
