These are prescription medications used to treat depression, a disease affecting over 15 million Americans. Some of the original drugs of this group were Nardil, Tofranil and Elavil. Although not technically an antidepressant, lithium, which used to treat manic depression, is often in this group. The side effects of prolonged and excessive use of these drugs are excessive urination or thirst, diarrhoea, vomiting, drowsiness, dizziness or muscle weakness. Some newer antidepressants that show great promise in treating this disease are Wellbutrin, Prozac and Zoloft. The incidence of side effects with these seem to be less than with the previously used medications.
Scientists have found that whether an individual has positive or negative sensations after smoking marijuana can be influenced by heredity. A recent study demonstrated that identical male twins were more likely than non-identical male twins to report similar responses to marijuana use, indicating a genetic basis for their sensations. Identical twins share all of their genes, and fraternal twins share about half.
السمع هي واحدة من الحواس الخمس التقليدية. وهو القدرة على الاحساس بالاهتزازات عن طريق جهاز مثل الأذن. عدم القدرة على السماع هو ما يسمى بالصمم في البشر والفقاريات الأخرى والسمع عملية تبدأ بالصوت المنبعث الذي يُعد المصدر ويمر بالأذن التي تستشعر الصوت وتلتقطه، وتنتهي بمركز السمع بالمخ. تتالف الأذن من ثلاث اجزاء: 1- خارج الأذن 2- وسط الأذن 3- داخل الأذن
And for the most part, it does not. Second sound was first detected in liquid helium 75 years ago and later seen within three solids. “All indications early on were that this was something that would really be confined to very few materials and only at very low temperatures,” Nelson says. As such, scientists thought they had hit the end of the road. “It wasn’t super clear what [second sound] could be apart from a scientific statement,” says Nicola Marzari, a materials scientist at the Swiss Federal Institute of Technology, in Lausanne, who was not involved in this study. “So, the entire field went dormant for many years.”

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.
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.

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.

Nicotine also is absorbed readily when tobacco is chewed. With regular use of tobacco, levels of nicotine accumulate in the body during the day and persist overnight. Thus, daily smokers or chewers are exposed to the effects of nicotine for 24 hours each day. Nicotine taken in by cigarette or cigar smoking takes only seconds to reach the brain but has a direct effect on the body for up to 30 minutes.

Long-term effects of heroin appear after repeated use for some period of time. Chronic users may develop collapsed veins, infection of the heart lining and valves, abscesses, cellulitis, and liver disease. Pulmonary complications, including various types of pneumonia, may result from the poor health condition of the abuser, as well as from heroin’s depressing effects on respiration.
