English contains several sound homographs, all with distinct histories. For example, the sound that means "something heard" descends from Latin sonus ("sound"), whereas the sound that means "to measure the depth of water" traces to Old French sonde ("sounding line"). Another sound, however, is the contemporary form of Old English's gesund. Gesund is related to several words in other languages, such as Old Saxon gisund ("sound"), Old Frisian sund ("fresh, unharmed, healthy"), and Gothic swinths ("sound" or "healthy"). Another relative is Old High German's gisunt ("healthy"), which led to modern German's gesund, the root of gesundheit.

In 1998, the Substance Abuse and Mental Health Services Administration’s (SAMHSA) National Household Survey on Drug Abuse showed that over 20 million people over the age of 12 reported having used one or more psychotherapeutic drugs (stimulants, sedatives, tranquilizers, and analgesics available through prescription) for non-medical purposes at some time in their lives. Stimulants, analgesics, and tranquilizers were the most widely used drugs of abuse that fit this category.
Benzodiazepines are the most widely prescribed tranquilizers and sleep-inducing medications. Drugs used to treat anxiety and tension are Valium, Xanax, Ativan, and Tranxene. Drugs used for sleeping are Dalamine, Restotril and Halcion. Possible side effects include drowsiness, poor coordination or light-headedness. Overuse of these drugs can lead to respiratory difficulties, sleeplessness, coma and even death.
Magic mushrooms are normally consumed orally (ie. eaten) either raw or dried out. Raw magic mushrooms are about 90% water. Amanita muscaria is not often eaten raw as the user can experience severe nausea. Magic mushrooms may also be cooked or combined in food dishes though heating generally breaks down the psychoactive substance. 1 to 5 grams are normally consumed.
