These days, drugs can be found everywhere, and it may seem like everyone's doing them. Many teens are tempted by the excitement or escape that drugs seem to offer. But learning the facts about drugs can help you see the risks of chasing this excitement or escape. Read on to learn more.

The Deal on Substances

Thanks to medical and drug research, there are thousands of drugs that help people. Antibiotics and vaccines have revolutionized the treatment of infections. There are medicines to lower blood pressure, treat diabetes, and reduce the body's rejection of new organs. Medicines can cure, slow, or prevent disease, helping us to lead healthier and happier lives. But there are also lots of illegal, harmful drugs that people take to help them feel good or have a good time.

How do drugs work? Drugs are chemicals or substances that change the way our bodies work. When you put them into your body (often by swallowing, inhaling, or injecting them), drugs find their way into your bloodstream and are transported to parts of your body, such as your brain. In the brain, drugs may either intensify or dull your senses, alter your sense of alertness, and sometimes decrease physical pain. A drug may be helpful or harmful. The effects of drugs can vary depending upon the kind of drug taken, how much is taken, how often it is used, how quickly it gets to the brain, and what other drugs, food, or substances are taken at the same time. Effects can also vary based on the differences in body size, shape, and chemistry.

Although substances can feel good at first, they can ultimately do a lot of harm to the body and brain. Drinking alcohol, smoking tobacco, taking illegal drugs, and sniffing glue can all cause serious damage to the human body. Some drugs severely impair a person's ability to make healthy choices and decisions. Teens who drink, for example, are more likely to get involved in dangerous situations, such as driving under the influence or having unprotected sex.

And just as there are many kinds of drugs available, there are as many reasons for trying drugs or starting to use drugs regularly. People take drugs just for the pleasure they believe they can bring. Often it's because someone tried to convince them that drugs would make them feel good or that they'd have a better time if they took them.

Some teens believe drugs will help them think better, be more popular, stay more active, or become better athletes. Others are simply curious and figure one try won't hurt. Others want to fit in. A few use drugs to gain attention from their parents. Many teens use drugs because they are depressed or think drugs will help them escape their problems. The truth is, drugs don't solve problems. Drugs simply hide feelings and problems. When a drug wears off, the feelings and problems remain - or become worse. Drugs can ruin every aspect of a person's life.

What are some of the more common drugs?


The oldest and most widely used drug in the world, alcohol is a depressant that alters perceptions, emotions, and senses.

How It's Used: Alcohol is a liquid that is drunk.

Effects & Dangers:

Addictiveness: Teens who use alcohol can become psychologically dependent upon it to feel good, deal with life, or handle stress. In addition, their bodies may demand more and more to achieve the same kind of high experienced in the beginning. Some teens are also at risk of becoming physically addicted to alcohol. Withdrawal from alcohol can be painful and even life threatening. Symptoms range from shaking, sweating, nausea, anxiety, and depression to hallucinations, fever, and convulsions.


Amphetamines are stimulants that accelerate functions in the brain and body. They come in pills or tablets. Prescription diet pills also fall into this category of drugs.

Street Names: speed, uppers, dexies, bennies

How They're Used: Amphetamines are swallowed, inhaled, or injected.

Effects & Dangers:

Addictiveness: Amphetamines are psychologically addictive. Users who stop report that they experience various mood problems such as aggression and anxiety and intense cravings for the drugs.

Cocaine and Crack 

Cocaine is a white crystalline powder made from the dried leaves of the coca plant. Crack, named for its crackle when heated, is made from cocaine. It looks like white or tan pellets.

Street Names for Cocaine: coke, snow, blow, nose candy, white, big C

Street Names for Crack: freebase, rock

How They're Used: Cocaine is inhaled through the nose or injected. Crack is smoked.

Effects & Dangers:

Addictiveness: These drugs are highly addictive, and as a result, the drug, not the user, calls the shots. Even after one use, cocaine and crack can create both physical and psychological cravings that make it very, very difficult for users to stop.

Cough and Cold Medicines (DXM)

Several over-the-counter cough and cold medicines contain the ingredient dextromethorphan (also called DXM). If taken in large quantities, these over-the-counter medicines can cause hallucinations, loss of motor control, and "out-of-body" (or disassociative) sensations.

Street Names: triple C, candy, C-C-C, dex, DM, drex, red devils, robo, rojo, skittles, tussin, velvet, vitamin D

How They're Used: Cough and cold medicines, which come in tablets, capsules, gel caps, and lozenges as well as syrups, are swallowed. DXM is often extracted from cough and cold medicines, put into powder form, and snorted.

Effects & Dangers:

Addictiveness: People who use cough and cold medicines and DXM regularly to get high can become psychologically dependent upon them (meaning they like the feeling so much they can't stop, even though they aren't physically addicted).


Depressants, such as tranquilizers and barbiturates, calm nerves and relax muscles. Many are legally available by prescription (such as Valium and Xanax) and are bright-colored capsules or tablets.

Street Names: downers, goof balls, barbs, ludes

How They're Used: Depressants are swallowed.

Effects & Dangers:

Addictiveness: Depressants can cause both psychological and physical dependence.

Ecstasy (MDMA)

This is a designer drug created by underground chemists. It comes in powder, tablet, or capsule form. Ecstasy is a popular club drug among teens because it is widely available at raves, dance clubs, and concerts.

Street Names: XTC, X, Adam, E, Roll

How It's Used: Ecstasy is swallowed or sometimes snorted.

Effects & Dangers:

Addictiveness: Although the physical addictiveness of Ecstasy is unknown, teens who use it can become psychologically dependent upon it to feel good, deal with life, or handle stress.


GHB, which stands for gamma hydroxybutyrate, is often made in home basement labs, usually in the form of a liquid with no odor or color. It has gained popularity at dance clubs and raves and is a popular alternative to Ecstasy for some teens and young adults. The number of people brought to emergency departments because of GHB side effects is quickly rising in the United States. And according to the U.S. Drug Enforcement Agency (DEA), since 1995 GHB has killed more users than Ecstasy.

Street Names: Liquid Ecstasy, G, Georgia Home Boy

How It's Used: When in liquid or powder form (mixed in water), GHB is drunk; in tablet form it is swallowed.

Effects & Dangers:

Addictiveness: When users come off GHB they may have withdrawal symptoms such as insomnia and anxiety. Teens may also become dependent upon it to feel good, deal with life, or handle stress.


Heroin comes from the dried milk of the opium poppy, which is also used to create the class of painkillers called narcotics - medicines like codeine and morphine. Heroin can range from a white to dark brown powder to a sticky, tar-like substance.

Street Names: horse, smack, Big H, junk

How It's Used: Heroin is injected, smoked, or inhaled (if it is pure).

Effects & Dangers:

Addictiveness: Heroin is extremely addictive and easy to overdose on (which can cause death). Withdrawal is intense and symptoms include insomnia, vomiting, and muscle pain.


Inhalants are substances that are sniffed or "huffed" to give the user an immediate rush or high. They include household products like glues, paint thinners, dry cleaning fluids, gasoline, felt-tip marker fluid, correction fluid, hair spray, aerosol deodorants, and spray paint.

How It's Used: Inhalants are breathed in directly from the original container (sniffing or snorting), from a plastic bag (bagging), or by holding an inhalant-soaked rag in the mouth (huffing).

Effects & Dangers:

Addictiveness: Inhalants can be very addictive. Teens who use inhalants can become psychologically dependent upon them to feel good, deal with life, or handle stress.


Ketamine hydrochloride is a quick-acting anesthetic that is legally used in both humans (as a sedative for minor surgery) and animals (as a tranquilizer). At high doses, it causes intoxication and hallucinations similar to LSD.

Street Names: K, Special K, vitamin K, bump, cat Valium

How It's Used: Ketamine usually comes in powder that users snort. Users often do it along with other drugs such as Ecstasy (called kitty flipping) or cocaine or sprinkle it on marijuana blunts.

Effects & Dangers:

Addictiveness: Teens who use it can become psychologically dependent upon it to feel good, deal with life, or handle stress.


LSD (which stands for lysergic acid diethylamide) is a lab-brewed hallucinogen and mood-changing chemical. LSD is odorless, colorless, and tasteless.

Street Names: acid, blotter, doses, microdots

How It's Used: LSD is licked or sucked off small squares of blotting paper. Capsules and liquid forms are swallowed. Paper squares containing acid may be decorated with cute cartoon characters or colorful designs.

Effects & Dangers:

Addictiveness: Teens who use it can become psychologically dependent upon it to feel good, deal with life, or handle stress.


The most widely used illegal drug in the United States, marijuana resembles green, brown, or gray dried parsley with stems or seeds. A stronger form of marijuana called hashish (hash) looks like brown or black cakes or balls. Marijuana is often called a gateway drug because frequent use often leads to the use of stronger drugs.

Street Names: pot, weed, blunts, chronic, grass, reefer, herb, ganja

How It's Used: Marijuana is typically smoked in cigarette (joints), hollowed-out cigars (blunts), pipes (bowls), or water pipes (bongs). Some people mix it into foods or brew it as a tea.

Effects & Dangers:

Addictiveness: Teens who use marijuana can become psychologically dependent upon it to feel good, deal with life, or handle stress. In addition, their bodies may demand more and more marijuana to achieve the same kind of high experienced in the beginning.


Methamphetamine is a powerful stimulant.

Street Names: crank, meth, speed, crystal, chalk, fire, glass, crypto, ice

How It's Used: It can be swallowed, snorted, injected, or smoked.

Effects & Dangers:

Addictiveness: Methamphetamine is highly addictive.


Nicotine is a highly addictive stimulant found in tobacco. This drug is quickly absorbed into the bloodstream when smoked.

How It's Used: Nicotine is typically smoked in cigarettes or cigars. Some people put a pinch of tobacco (called chewing or smokeless tobacco) into their mouths and absorb nicotine through the lining of their mouths.

Effects & Dangers:

Addictiveness: Nicotine is as addictive as heroin or cocaine, which makes it extremely difficult to quit. Those who start smoking before the age of 21 have the hardest time breaking the habit.


Rohypnol (pronounced: ro-hip-nol) is a low-cost, increasingly popular drug. Because it often comes in presealed bubble packs, many teens think that the drug is safe.

Street Names: roofies, roach, forget-me pill, date rape drug

How It's Used: This drug is swallowed, sometimes with alcohol or other drugs.

Effects & Dangers:

Addictiveness: Users can become physically addicted to rohypnol, so it can cause extreme withdrawal symptoms when users stop.

قيادة السيارة تحت تأثير المخدرات Drugs and Driving





كيف تؤثر الخمور والمخدرات على مهارة القيادة؟ عندما تقود سيارتك, فإن اليدين والقدمين والعينين تتحكم في المركبة والدماغ يكون مسئولا عن التحكم والتنسيق بين هذه الأعضاء. ولقيادة آمنة يجب أن تبقى متيقظا وبكامل حواسك ولديك القدرة على التفاعل السريع مع ظروف الطريق والمركبة. الخمر والمخدرات الأخرى تؤثر سلبا على وظائف المخ والجسم معا وتجعل كل خبرة سابقة مع القيادة تضمحل مهما طالت فترة هذه الخبرة. ومهما كان تأثير المواد المحظورة سواء مخدرا أو منشطا, فإنه يؤدي في النهاية لنفس النتيجة وهي الحوادث.


الخمر والمثبطات الأخرى: الخمر والمثبطات(المركنات) الأخرى تعمل على تقليل درجة اليقظة والوعي والقدرة على التنسيق التي يحتاجها قائد المركبة لقيادة آمنة. فنظر السائق المخمور يكون مشوشا أو حتى مزدوج الرؤية كما يفتقد القدرة على تحديد عمق وأبعاد ما يراه أمامه فلا يستطيع الحكم جيدا هل السيارات أو المارة أمامه بعيدون أم قريبون وهذا ما يؤدي لمشاكل جمة. ومن أكبر المشاكل التي قد تواجه السائق المخمور هو ثقته الزائدة بنفسه وعدم إدراكه أن مهارته في القيادة ليست بالمستوى المطلوب لقيادة آمنه. فتجده يقود بسرعة عالية ويتجاوز السيارات والشاحنات بطريقة خطرة ويقوم بحركات خرقاء بعيدة عن كل أصول السلامة وغالبا ما ينتهي هذا الشيء بمأساة.


تشترك المهدئات وبعض مسكنات الألم وأدوية الاحتقان والحساسية مع الخمر في تثبيط نشاط الدماغ والجسم وتؤدي لنفس المشاكل التي يؤدي إليها القيادة تحت تأثير الخمر. وتزيد المشاكل أكثر إذا تم استعمال هذه الأدوية مع الخمر. لذا ينصح المريض باستشارة طبيبه وسؤاله عن تأثيرات هذه الأدوية ومدى قدرته على القيادة أم لأ.

المنشطات: المواد التي لها مفعول منشط كالقهوة والأمفيتامينات والكوكايين تؤدي لتحسن ملحوظ في الانتباه لكن هذا لا يعني أنها تحسن أو تزيد من مهارة السائق في القيادة والتحكم. من المهم الاشارة هنا إلى أن السائقين الذين يتناولون القهوة مثلا ليبقوا مستيقظين, يجب أن يعرفوا أن المفعول المنشط للقهوة قد ينتهي فجأة مع التعب والقيادة المرهقة وهذا يؤدي لنوم مفاجئ أثناء القيادة والنتيجة الحتمية لذلك كارثية غالبا. الأمفيتامينات لا تؤثر على مهارة القيادة سلبا إذا كانت بالجرعات التي يحددها الطبيب المعالج ولكن إذا أخذت بجرعات كبيرة أو دون إشراف طبي, فتؤدي لمشاكل في القيادة تتمثل في الشعور بالثقة الزائدة والميول العدوانية تجاه السائقين الآخرين أو المارة وهذا ما قد يدفع السائق للارتطام بالسيارة متعمدا. الكوكايين يتميز ببعض التأثيرات على النظر فقد يؤدي بالإضافة لرؤية مشوشة إلى رؤية أضواء وأشياء وهمية تتحرك في المجال الجانبي للرؤية وهذا يؤدي به إلى الانحراف عن هذه الأشياء الوهمية بشكل مفاجئ وقد يعرضه هذا الشيء للحوادث. الكوكايين أيضا يجعل السائق يسمع أصواتا وهمية(هلاوس سمعية) قد تكون مرتبطة بالسيارة كصوت صادر من المحرك أو من خارج السيارة كأبواق السيارات الأخرى وهذا يؤدي به للارتباك وعدم القدرة على التركيز أيضا. الكوكايين أيضا يسبب هلاوس في حاسة الشم كأن يتوهم أنه يشم رائحة بنزين متسرب أو دخان وهذا أيضا يؤدي لإرباكه وانشغاله عن القيادة.

الحشيش وحبوب الهلوسة: يؤثر الحشيش على قدرة السائق على تقدير عمق الصورة التي يراها كما يؤثر أيضا على التركيز ويبطئ من ردة فعل السائق عند حدوث طارئ وهذا ما قد يؤدي إلى كارثة. تأثير المهلسات شبيه بتأثير الحشيش على إدراك السائق لعمق الصورة والتركيز ويضاف إلى ذلك تأثيره السلبي على مزاج السائق مما يؤدي لميول عدوانية لأقل مهيج خارجي.



1) لا ينصح بشرب الخمر أو تعاطي أي نوع من المواد المحظورة (مثبطة أو منشطة) من الأساس إلا بشكل قانوني سواء عن طريق الوصفة الطبية أو أي جهة مصرح لها بذلك.

2) لا تجعل رجل الأمن أو أي سلطة هو الرقيب عليك, الرقيب يجب أن يكون من داخلك

3) كلما زادت الكمية المتناولة من الخمر أو أي مادة أخرى كلما زادت الفترة التي يجب أن ينتظرها السائق قبل قيادة السيارة بشكل آمن.

4) لا يوجد دواء أو أي مواد طبيعية أو صناعية تزيل الخمر من الدم أو تأثيره بشكل سريع وعاجل. لذا يجب الانتظار حتى ينتهي مفعول الخمر ثم قيادة السيارة بشكل آمن. الجرعة الواحدة(الكأس القياسي الواحد) قد يستغرق ساعة ليزول ثلثاه من الدم ولكن تأثير الخمر قد يستمر لفترة أطول.

5) لا تعني سلامتك في المرات السابقة أنك تستطيع السيطرة على الأمور كل مرة. تأثيرات الخمر والمخدرات بعد دخولها للجسم خاضعة لعدة عوامل قد لا تدركها.

6) الكافايين (القهوة) تؤدي لزيادة ولاستمرار اليقظة لكن لا تحسن الانتباه بشكل حقيقي والقيادة تحت تأثير الكافيين يؤدي للإرهاق الذي قد يؤدي للنوم المفاجئ دون سابق إنذار حتى مع كون تركيز الكافيين في الدم عاليا.

7) الحشيش والأمفيتامينات والكوكايين لا تزيد من مهارة القيادة حتى لو كان مفعولها منشطا. النشاط المصاحب لهذا المواد كاذب. وقد يجعل السائق يستمر في المكابرة التي تؤدي به لكارثة.

8) الكابتاغون شأنه شأن أي منشط آخر يعطيك إحساسا بالنشاط والانتباه ولكنه شعورا مزيفا, وذلك يعني أن تصرفاتك ستكون طائشة وليست موجهة توجيها صحيحا.

9) مواد الهلوسة والكوكايين تزيد من الشعور بالعدوانية والرغبة في إيذاء الآخرين, والقيادة وبالذات داخل المدن المزدحمة تؤدي للغضب السريع في الأشخاص الطبيعيين. المخدرات تزيد هذه الرغبة في العدوانية بشكل كبير جدا.

10) حال شعورك بالتعب على الخطوط الطويلة وأردت أن تستمر في هذه الحياة وتصل لهدفك في النهاية فأفضل مخدر أو منشط تتناوله هو.................قسط من النوم. نعم أوقف مركبتك ونم كفايتك وبعد الاستيقاظ, تكمل طريقك بأمان بإذن الله.

11) تذكر......رب العمل الذي ينتظر منك إتمام عملك أو نقلك لبضائعه بأسرع ما يمكن لن يعيل أولادك حال وفاتك نتيجة حادث مروري نتيجة تناولك للكابتاغون أو أي منشط آخر.
