When addicted individuals stop using cocaine, they often become depressed. This also may lead to further cocaine use to alleviate depression. Prolonged cocaine snorting can result in ulceration of the mucous membrane of the nose and can damage the nasal septum enough to cause it to collapse. Cocaine-related deaths are often a result of cardiac arrest or seizures followed by respiratory arrest.
Some fatal accidents have occurred during states of LSD intoxication. Many LSD users experience flashbacks, recurrence of certain aspects of a person’s experience, without the user having taken the drug again. A flashback occurs suddenly, often without warning, and may occur within a few days or more than a year after LSD use. Flashbacks usually occur in people who use hallucinogens chronically or have an underlying personality problem; however, otherwise healthy people who use LSD occasionally may also have flashbacks. Bad trips and flashbacks are only part of the risks of LSD use.
يستخدم الصوت كوسيلة تواصل بين الكائنات الحية، فمثلاً عند الإنسان، يقوم الشخص بإخراج الهواء من الرئتين بكميات معينة وتصطدم أثناء خروجها بالأحبال الصوتية مؤدية إلى اهتزازها وتكوين موجات مختلفة تخرج عن طريق الفم حتى تكون الأحرف المنطوقة، كما يستخدم عند الحيوانات في عمليات التزاوج والنداء والعراك بينها، فارتفاع الصوت يؤدي إلى إحداث حالة الخوف عند الطرف الآخر.
في هذه اللحظة ظهر لي أمل فبدأت في الخروج من وحدتي وظل يتحدث معي عن الإدمان والتبطيل والتعافي والتغيير. وكان يسمعني جيدًا ويهتم بحديثي. بعد ذلك قام الدكتور بتحويلي من المستشفى إلى بيت إعادة تأهيل للمدمنين. دخلت هذا البيت ووجدت أن كلهم مدمنين مثلي لكن مبطلين فترات مختلفة، ووجدت أنشطة عديدة تقام في هذا البيت كلها أنشطة جماعية نشترك فيها كلنا، وبدأت أعرف نفسي من جديد في هذا البيت من خلال برنامج 12 خطوة، وأخذت مشرف شخصي أتكلم معه وأشاركه أفكاري وأحاسيسي ومشاعري. فبدأت أضع يدي على الخلل في شخصيتي وبدأت أتعامل معه. وفترة تبطيلي تزيد يوم بعد يوم وأزداد الثقة بي وبدأ الجميع يشجعونني بما فيهم زوجتي وأخوتي حتى بدأت أتغير في أشياء كثيرة وسلوكيات كثيرة.

تدخل الموجات الصوتية إلى الأذن بعد أن يقوم الصيوان بتجميعها، ثم تمر عبر القناة السمعية الخارجية (الصورة:gg) إلى الطبلة (الصورة:tf) التي تحولها إلى اهتزازات تنتقل إلى المطرقة (الصورة:h) فالسندان (الصورة:a) فالركاب (الصورة:s) وثم إلى القوقعة التي يؤدي اهتزاز القناتين السمعية (الصورة:tht) والدهليزية (الصورة:vht) فيها إلى توليد سلسلة من الذبذبات تنتقل بواسطة العصب السمعي إلى المخ بصورة سيالات عصبية، حيث تترجم هناك إلى أصوات نسمعها.

Meet Arlo Pear! He's a family man with a loving wife, a rebellious daughter, twin sons, and a half-dead dog, he's also got a nice job with the city in New Jersey. He's a mass transit engineer. But one day Arlo is fired so he must try to get another job. He finds a similar one to his old one, except it's in Boise, Idaho. Sounds good to Arlo, so he can finally get away from his insane neighbor who has a lawn mower the size of Pennsylvania. Only problem, how to break it to the family?

It is no wonder that Duncan, a graduate student at the Massachusetts Institute of Technology, could not quite believe his eyes. To ensure that he had not made a mistake, he quadruple-checked everything within his set-up, ran the experiment again, and took a mental-health break. “I tried to get some sleep, knowing that I wouldn’t be able to tell if the experiment was successful or not for several more hours, but I was finding it pretty difficult to shut down for the night,” he recalls. When Duncan’s alarm went off the next morning, he ran to his computer (still in his pajamas) and crunched the new measurements only to confront the same result: Heat had still moved impossibly fast.
Environmental factors such as the availability of marijuana, expectations about how the drug would affect them, the influence of friends and social contacts, and other factors that differentiate identical twins’ experiences also were found to have an important effect; however, it also was discovered that the twins’ shared or family environment before age 18 had no detectable influence on their response to marijuana.

تتألف الموجة الصوتية أو الأمواج الصوتية في أي وسط من حركة اهتزازية حركة اهتزازية سريعة للجزيئات التي تألف الوسط. فحركة إحدى جزيئات الوسط تؤدي إلى اضطراب الجزيئات المجاورة، وهذه بدورها تقوم بنفس العمل، وهكذا دواليك، بحيث أن موجة من الاضطراب تعبر الوسط ابتداء من نقطة الحركة الأولى. وعندما تهتز الشوكة الرنانة في الهواء، فإن حركة الشعبة المهتزة إلى الأمام تضغط الهواء المجاور. إلا أنه سرعان ماتعود هذه المنطقة المنضغطة من الهواء إلى حالتها الاعتيادية بفضل الخاصة المطاطية للهواء وعلى حساب انضغاط المناطق المجاورة، بحيث أن موجة من الضغط الزائد تنتشر ابتداء من الشعبة المهتزة من الشوكة الرنانة، وبنفس الطريقة فإن حركة الشعبة المهتزة إلى الخلف تولد موجة من الضغط الناقص أو التخلخل.
