Nicotine is highly addictive. It is both a stimulant and a sedative to the central nervous system. The ingestion of nicotine results in an almost immediate kick because it causes a discharge of epinephrine from the adrenal cortex. This stimulates the central nervous system, and other endocrine glands, which causes a sudden release of glucose. Stimulation is then followed by depression and fatigue, leading the abuser to seek more nicotine. Nicotine is absorbed readily from tobacco smoke in the lungs, and it does not matter whether the tobacco smoke is from cigarettes, cigars, or pipes.

ويحمل التعاطي معه في أحيان كثيرة خطر الوفاة نتيجة للجرعة الزائدة، أو المغامرة غير المحسوبة، وهذا بدوره يمكن أن يؤدي إلى زيادة في عدد الأرامل الشباب، والأطفال الأيتام في عمر صغيرة، وحتى في حالات التعاطي الأقل خطورة، فإن المخدر يمكن أن يؤثر في إنتاجية الفرد، وقدراته في مجال عمله تأثيراً كبيراً، ويمكن أن يتسبب التعاطي المكثف للمخدرات، مثل الماريجوانا في إعاقة الأداء الوظيفي المعرفي للفرد، ويقلل من مستوياته الدافعية، وقد تؤدي هذه العقاقير بالإضافة إلى الإصابة بالبارانويا، والأوهام، والاضطرابات الذهنية، والعديد من الآثار الأخرى التي قد تؤثر تأثيراً سلبياً على التنسيق في مجال العمل.
Today, athletes and others abuse anabolic steroids to enhance performance and also to improve physical appearance. Anabolic steroids are taken orally or injected, typically in cycles of weeks or months (referred to as cycling), rather than continuously. Cycling involves taking multiple doses of steroids over a specific period of time, stopping for a period, and starting again. In addition, users often combine several different types of steroids to maximize their effectiveness while minimizing negative effects (referred to as stacking).
Death from inhalants usually is caused by a very high concentration of fumes. Deliberately inhaling from an attached paper or plastic bag or in a closed area greatly increases the chances of suffocation. Even when using aerosols or volatile products for their legitimate purposes (i.e., painting, cleaning), it is wise to do so in a well-ventilated room or outdoors.

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.
These are stimulants used primarily to delay the onset of mental and physical fatigue. Students studying long hours for exams, athletes who feel the drugs will improve their performance, and workers who want to stay awake on the job often use stimulants. These drug compounds are often found in diet pills which, if misused, can lead to anorexia nervosa. Anorexia nervosa is a pathological loss of appetite thought to be psychological in origin that is manifested in extreme dieting and excessive thinness. Caffeine is also found in many beverages, pain medications, and allergy and cold remedies.

من التحديات الفنية التي تواجه علاج الادمان ،حيث أن البعض يظن أن الانتكاسة تأتي فجأة بلا مقدمات ، ولكن هذا غير صحيح ... بالانتكاسة تسبقها أفكار تعاطي ، حيث تتوارد على ذهن المدمن افكار التعاطي وآثاره من نشوة ووهم أنه ينسى بذلك همومه وآلامه ، وقد يؤدي تراكم هذه الأفكار على ذهن  المدمن دون التزامه بأحد البرامج العلاجية  لوقوعه في التعاطي مرة أخرى وانتكاسته التي تجعله يفقد السيطرة على مرضه وسلوكياته ، ويعود مرة أخرى لما كان فيه من تعاطي وفقدان سيطرة ..


Research also indicates that some users might turn to other drugs to alleviate some of the negative effects of anabolic steroids. For example, a study of 227 men admitted in 1999 to a private US treatment centre for dependence on heroin or other opioids found that 9.3 percent had abused anabolic steroids before trying any other illicit drug. Of these 9.3 percent, 86 percent first used opioids to counteract insomnia and irritability resulting from the anabolic steroids. [2]
MDMA also is related in its structure and effects to methamphetamine, which has been shown to cause degeneration of neurons containing the neurotransmitter dopamine. Damage to these neurons is the underlying cause of the motor disturbances seen in Parkinson’s disease. Symptoms of this disease begin with lack of coordination and tremors and can eventually result in a form of paralysis.
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.

The effects of taking magic mushrooms are similar to that of taking LSD, but the trip will normally be shorter and milder. It takes 30 minutes to two hours to be noticeable. A taker might feel euphoric, confident, excited or relaxed. One may feel more emotionally sensitive, creative or enlightened. Magic mushrooms are hallucinogens, as such hallucinations can occur, especially with larger doses. Colours, sounds and objects can be distorted and senses might be confused, such as thinking you can see sounds. One?s senses can also be slowed down and the experience can feel like dreaming. Whilst not being addictive, one becomes tolerant of magic mushrooms quickly, requiring a greater dose to achieve the same high.

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.

Magic mushrooms can make you feel nauseated, tired and disorientated. One can also have ?bad trip? which is a frightening experience during which the user will experience severe anxiety or paranoia. There?s no way to tell if a particular use of magic mushrooms will be a bad or good trip and there?s no way of going back other than waiting for the effects to wear off. As a hallucinogen, you?re not always aware and in complete control of what you do, which could cause you to do or get involved in dangerous situations.
These products, obtainable over the internet and sometimes still sold in health food stores, are also available at some gyms, raves, nightclubs, gay male parties, college campuses, and the street. They are commonly mixed with alcohol (which may cause unconsciousness), have a short duration of action, and are not easily detectable on routine hospital toxicology screens. [1]
أظهر "تقرير المخدرات العالمي لعام 2016"أظهر تقرير، الذي أصدره "البرنامج العالمي لمكافحة المخدرات والجريمة" (UNODC)، التابع للأمم المتحدة، أن نحو 250 مليون شخصاً في العالم، أي نحو 5% تعاطوا المخدرات غير المشروعة، بمختلف أنواعها. ولفت إلى أن 144 مليوناً يتعاطون البانجو، و29 مليوناً يتعاطون منشطات وحبوب "أكتستاسي"، و14 مليوناً يتعاطون الكوكايين، و13.5 مليوناً يتعاطون الأفيون، و9 ملايين يتعاطون الهيروين.
Physical effects of cocaine use include constricted peripheral blood vessels, dilated pupils, and increased temperature, heart rate, and blood pressure. The duration of cocaine’s immediate euphoric effects, which include hyper-stimulation, reduced fatigue, and mental clarity, depends on the route of administration. The faster the absorption, the more intense the high.
But dramatic improvements in numerical simulations helped to revive the field roughly five years ago—allowing scientists to recognize that the phenomenon might be more widespread. Gang Chen, an engineer at MIT, for example, was able to predict that second sound might be visible within graphite at rather balmy temperatures. That prediction electrified Duncan, who tested it just as soon as he could—eventually putting the rest of his pursuits on the back burner, once the results proved to be so counterintuitive.   
Addiction to nicotine results in withdrawal symptoms when a person tries to stop smoking. For example, a study found that when chronic smokers were deprived of cigarettes for 24 hours, they had increased anger, hostility, and aggression, and loss of social cooperation. Persons suffering from withdrawal also take longer to regain emotional equilibrium following stress. During periods of abstinence and/or craving, smokers have shown impairment across a wide range of psychomotor and cognitive functions, such as language comprehension. 									

valid, sound, cogent, convincing, telling mean having such force as to compel serious attention and usually acceptance. valid implies being supported by objective truth or generally accepted authority. a valid reason for being absent a valid marriage sound implies a basis of flawless reasoning or of solid grounds. a sound proposal for reviving the economy cogent may stress either weight of sound argument and evidence or lucidity of presentation. the prosecutor's cogent summation won over the jury convincing suggests a power to overcome doubt, opposition, or reluctance to accept. a convincing argument for welfare reform telling stresses an immediate and crucial effect striking at the heart of a matter. a telling example of bureaucratic waste
ثم قررت السفر للخليج فأكيد في الخليج سأتوقف عن الهيروين لأنه لا يوجد هيروين هناك. ولكنني سافرت إلى الخليج وبحثت عن الهيروين حتى استطعت الوصول إليه وكنت أتعاطى بصفة مستمرة هناك حتى بدأت المشاكل تحاصرني مرة أخرى لأني كنت أسرق من العمل ولا أذهب بانتظام حتى اكتشفوا سرقتي وتم التحقيق معي وتم ترحيلي من هذه البلد مع مراعاة عدم دخولي لهذه البلد لمدة ليست قصيرة. وعدت إلى مصر واستمريت في تعاطي الهيروين.

For recreational use, laughing gas is normally inhaled from a balloon which has been filled from a canister. Once inhaled the effects of the drug are felt within five to ten seconds and, depending how much has been inhaled, can last for anywhere between thirty seconds and four minutes. Ten to fifteen minutes after inhalation the high subsides, around an hour later laughing gas will have been completely eliminated from the body, long term effects remain.
