Cocaine

Cocaine (benzoylmethylecgonine) (INN) is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant.[5] The name comes from "coca" in addition to the alkaloid suffix -ine, forming cocaine. It is a stimulant of the central nervous system, an appetite suppressant, and a topical anesthetic. Specifically, it is a serotonin–norepinephrine–dopamine reuptake inhibitor, which mediates functionality of these neurotransmitters as an exogenous catecholamine transporter ligand. Because of the way it affects the mesolimbic reward pathway, cocaine is addictive.[6]
Unlike most molecules, cocaine possesses pockets with both high hydrophilic and lipophilic efficiency, violating the rule of hydrophilic-lipophilic balance. This causes it to cross the blood-brain barrier with vastly superior reinforcement than to other psychoactive chemicals.
Its possession, cultivation, and distribution are illegal for non-medicinal and non-government sanctioned purposes in virtually all parts of the world. Although its free commercialization is illegal and has been severely penalized in virtually all countries, its use worldwide remains widespread in many social, cultural, and personal settings.

In July 1985, Hudson joined his old friend Doris Day for the launch of her new TV cable show, Doris Day's Best Friends. His gaunt appearance and nearly incoherent speech were so shocking it was broadcast again all over the national news shows that night and for weeks to come.
Hudson had been diagnosed with HIV on June 5, 1984, but when the signs of illness became apparent a few months later his publicity staff and doctors told the public he had inoperable liver cancer. During most of 1984 and 1985, Hudson kept his illness a secret while continuing to work and at the same time travel to France and other countries seeking a cure, or at least treatment to slow the progress of the disease. It was not until July 25, 1985, while in Paris for treatment, that Hudson issued a press release announcing that he was dying of AIDS. In another press release a month later, Hudson speculated he might have contracted HIV through transfused blood from an infected donor during the multiple blood transfusions he received during his heart bypass procedure in November 1981. He flew back to Los Angeles on July 31, where he was so physically weak he was taken off by stretcher from the Air boning747 he had chartered and upon which he and his medical attendants were the only passengers.[15] He was flown by helicopter to Cedars Sinai Hospital, where he spent nearly a month undergoing further treatment. When the doctors told him there was no hope of saving his life, since the disease had progressed into the advanced stages, Hudson returned to his house, "The Castle", in Beverly Hills, where he remained in seclusion until his death on October 2, 1985 at 8:37 a.m. PDT. He was a month and a half away from his 60th birthday.
The disclosure of Hudson's HIV status provoked widespread public discussion of his homosexuality. In its August 15, 1985 issue, People published a story that discussed his disease in the context of his sexuality. The largely sympathetic article featured comments from famous show business colleagues such as Angie Dickinson, Robert Stack and Mamie Van Doren, who acknowledged knowing about Hudson's homosexuality and expressed their support for him.[9] At that time People had a circulation of more than 2.8 million[16], and as a result of this and other stories Hudson's homosexuality became fully public.
Among activists who were seeking to de-stigmatize AIDS and its victims, Hudson's revelation of his own infection with the disease was viewed as an event that could transform the public's perception of AIDS. Shortly after Hudson's press release disclosing his infection, William M. Hoffman, the author of As Is, a play about AIDS that appeared on Broadway in 1985, stated: "If Rock Hudson can have it, nice people can have it. It's just a disease, not a moral affliction."[9] At the same time, Joan Rivers was quoted as saying: "Two years ago, when I hosted a benefit for AIDS, I couldn't get one major star to turn out. ... Rock's admission is a horrendous way to bring AIDS to the attention of the American public, but by doing so, Rock, in his life, has helped millions in the process. What Rock has done takes true courage."[9] Morgan Fairchild said that "Rock Hudson's death gave AIDS a face".[17] In a telegram Hudson sent to a September 1985 Hollywood AIDS benefit, Commitment to Life, which he was too ill to attend in person, Hudson said: "I am not happy that I am sick. I am not happy that I have AIDS. But if that is helping others, I can at least know that my own misfortune has had some positive worth."[3]
Hudson's revelation had an immediate impact on visibility of AIDS, and on funding of medical research related to the disease. Shortly after his death, People reported: "Since Hudson made his announcement, more than $1.8 million in private contributions (more than double the amount collected in 1984) has been raised to support AIDS research and to care for AIDS victims (5,523 reported in 1985 alone). A few days after Hudson died, at 59, on Oct. 2, 1985, Congress set aside $221 million to develop a cure for AIDS."[18] Organizers of the Hollywood AIDS benefit, Commitment to Life, reported that after Hudson's announcement that he was suffering from the disease, it was necessary to move the event to a larger venue to accommodate the increased attendance.[19]
However, Hudson's revelation did not immediately dispel the stigma of AIDS. Although then-president Ronald Reagan and his wife Nancy Reagan were friends of Hudson, Reagan, who was viewed by some as indifferent to the disease and its sufferers, made no public statement concerning Hudson's condition.[20] At the same time, privately, Reagan called Hudson in his Paris hospital room where he was being treated in July 1985, and Nancy Reagan telephoned French President Francois Mitterrand to ensure that Hudson would receive the best possible care.[9] Reagan's first public mention of the disease came in response to questions at a September 15, 1985 press conference, nearly two months after Hudson's announcement. In those remarks, Reagan called medical research on AIDS a "top priority". However, when asked, "If you had younger children, would you send them to a school with a child who had AIDS?," Reagan responded equivocally: "[G]lad I'm not faced with that problem today. ... I can understand both sides of it."[20] Several days later, Reagan sent a telegram to the Commitment to Life AIDS benefit, in which he reiterated his position that his administration would make stopping the spread of AIDS a top priority.[19] Nevertheless, Reagan did not publicly address AIDS at length for another two years.[21]
In addition, a controversy arose concerning Hudson's participation in a scene in the television drama Dynasty in which he shared a kiss with actress Linda Evans. When filming the scene Hudson was aware that he had AIDS, but did not inform her. Some felt that he should have disclosed his condition to her beforehand.[22] At the time, it was known that the virus was present in low quantities in saliva and tears, but there had been no reported cases of transmission by kissing.[23] Nevertheless, the Centers for Disease Control and Prevention had warned against exchanging saliva with members of groups perceived to be at high risk for AIDS.[18] According to comments given in August 1985 by Ed Asner, then president of the Screen Actors Guild, Hudson's revelation caused incipient "panic" within the film and television industry. Asner said that he was aware of scripts being rewritten to eliminate kissing scenes.[24] Later in the same year, the Guild issued rules requiring that actors be notified in advance of any "open-mouth" kissing scenes, and providing that they could refuse to participate in such scenes without penalty.[25] Linda Evans herself appears not to have been angry at Hudson: she asked to introduce the segment of the 1985 Commitment to Life benefit that was dedicated to Hudson.[19]
Hudson was cremated and his ashes scattered at sea.

Freddie Mercury and AIDS

According to his partner Jim Hutton, Mercury was diagnosed with AIDS shortly after Easter of 1987.[74] Around that time, Mercury claimed in an interview to have tested negative for HIV.[26] Despite the denials, the British press pursued the rampant rumours over the next few years, fuelled by Mercury's increasingly gaunt appearance, Queen's absence from touring, and reports from former lovers to various tabloid journals - by 1990 the rumours about Mercury's health were rife.[75] Towards the end of his life, he was routinely stalked by photographers, while the daily tabloid newspaper The Sun featured a series of articles claiming that he was seriously ill; notably in an article from November 1990 which featured an image of a haggard looking Mercury on the front page accompanied by the headline "It's official - Freddie is seriously ill".[76]
However, Mercury and his inner circle of colleagues and friends, whom he felt he could trust, continually denied the stories, even after one front page article published on 29 April 1991, which showed Mercury appearing very haggard in what was now a rare public appearance.[77] Brian May confirmed in a 1993 interview that Mercury had informed the band of his illness much earlier.[78] Filmed in May 1991, the music video for "These Are the Days of Our Lives" features a painfully thin Mercury, which are his final scenes in front of the camera.[79]
After the conclusion of his work with Queen in June 1991, Mercury retired to his home in Kensington. His former partner, Mary Austin, had been a particular comfort in his final years, and in the last few weeks of his life made regular visits to his home to look after him.[80] Near the end of his life, Mercury was starting to lose his sight, and his deterioration was so overpowering he couldn't get out of bed.[80] Due to his worsening condition, Mercury decided to hasten his death by refusing to take his medication.[80]
On 22 November 1991, Mercury called Queen's manager Jim Beach over to his Kensington home, to discuss a public statement. The next day, 23 November, the following announcement was made to the press on behalf of Mercury:[81]
Following the enormous conjecture in the press over the last two weeks, I wish to confirm that I have been tested HIV positive and have AIDS. I felt it correct to keep this information private to date to protect the privacy of those around me. However, the time has come now for my friends and fans around the world to know the truth and I hope that everyone will join with me, my doctors, and all those worldwide in the fight against this terrible disease. My privacy has always been very special to me and I am famous for my lack of interviews. Please understand this policy will continue.
A little over 24 hours after issuing that statement, Mercury died on the evening of 24 November 1991 at the age of 45, at his home in Kensington.[63] The official cause of death was bronchial pneumonia resulting from AIDS.[82] The news of his death had reached newspaper and television crews by the early hours of 25 November.[83]
On 27 November, Mercury's funeral service was conducted by a Zoroastrian priest. An intensely private man, Mercury's service was for 35 of his close friends and family, with Elton John and the remaining members of Queen among those in attendance.[84][85] Mercury was cremated at Kensal Green Cemetery, West London, with the whereabouts of his ashes believed to be known only to Mary Austin.[86]
In his will, Mercury left the vast majority of his wealth, including his home and recording royalties, to Mary Austin, and the remainder to his parents and sister. He further left £500,000 to his chef Joe Fanelli, £500,000 to his personal assistant Peter Freestone, £100,000 to his driver Terry Giddings, and £500,000 to Jim Hutton.[87] Mary Austin continues to live at Mercury's home, Garden Lodge, Kensington, with her family.[87] Hutton was involved in a 2000 biography of Mercury, Freddie Mercury, the Untold Story, and also gave an interview for The Times for what would have been Mercury's 60th birthday

aids

Human Immunodeficiency Virus is a lot like other viruses, including those that cause the "flu" or the common cold. But there is an important difference – over time, your immune system can clear most viruses out of your body. That isn't the case with HIV – the human immune system can't seem to get rid of it. Scientists are still trying to figure out why.
We know that HIV can hide for long periods of time in the cells of your body and that it attacks a key part of your immune system – your T-cells or CD4 cells. Your body has to have these cells to fight infections and disease, but HIV invades them, uses them to make more copies of itself, and then destroys them.
Over time, HIV can destroy so many of your CD4 cells that your body can't fight infections and diseases anymore. When that happens, HIV infection can lead to AIDS.

que le pasaria a tu bebe si estas embarazada y fumas

Why is it so dangerous to smoke during pregnancy?

Cigarette smoke contains more than 4,000 chemicals, including truly nasty things like cyanide, lead, and at least 60 cancer-causing compounds. When you smoke during pregnancy, that toxic brew gets into your bloodstream, your baby's only source of oxygen and nutrients.

While none of those 4,000-plus chemicals is good for your baby (you would never add a dollop of lead and cyanide to his strained peaches), two compounds are especially harmful: nicotine and carbon monoxide. These two toxins account for almost every smoking-related complication in pregnancy, says ob-gyn James Christmas, director of Maternal Fetal Medicine for Commonwealth Perinatal Associates at Henrico Doctors' Hospital in Richmond, Virginia.

The most serious complications — including stillbirth, premature delivery, and low birth weight — can be chalked up to the fact that nicotine and carbon monoxide work together to reduce your baby's supply of oxygen. Nicotine chokes off oxygen by narrowing blood vessels throughout your body, including the ones in the umbilical cord. It's a little like forcing your baby to breathe through a narrow straw. To make matters worse, the red blood cells that carry oxygen start to pick up molecules of carbon monoxide instead. Suddenly, that narrow straw doesn't even hold as much oxygen as it should.

How will smoking affect my baby?

A shortage of oxygen can have devastating effects on your baby's growth and development. On average, smoking during pregnancy doubles the chances that a baby will be born too early or weigh less than 5 1/2 pounds at birth. Smoking also more than doubles the risk of stillbirth.

Every cigarette you smoke increases the risks to your pregnancy. A few cigarettes a day are safer than a whole pack, but the difference isn't as great as you might think. A smoker's body is especially sensitive to the first doses of nicotine each day, and even just one or two cigarettes will significantly tighten blood vessels. That's why even a "light" habit can have an outsize effect on your baby's health.

How smoking affects your baby:

Weight and size
On average, a pack-a-day habit during pregnancy will shave about a half-pound from a baby's birth weight. Smoking two packs a day throughout your pregnancy could make your baby a full pound or more lighter. While some women may welcome the prospect of delivering a smaller baby, stunting a baby's growth in the womb can have negative consequences that last a lifetime.

Body and lungs
Undersize babies tend to have underdeveloped bodies. Their lungs may not be ready to work on their own, which means they may spend their first days or weeks attached to a respirator. After they're breathing on their own (or even if they did from the start), these babies may have continuing breathing problems — because of delayed lung development or other adverse effects of nicotine. Children whose mothers smoked during pregnancy are especially vulnerable to asthma, and have double or even triple the risk of sudden infant death syndrome (SIDS).
Heart
Babies whose mother smoked in the first trimester of pregnancy are more likely to have a heart defect at birth.
In a U.S. Centers for Disease Control and Prevention (CDC) study published in February 2011, these babies' risk of having certain types of congenital heart defects was 20 to 70 percent higher than it was for babies whose moms didn't smoke. The defects included those that obstruct the flow of blood from the right side of the heart into the lungs (right ventricular outflow tract obstructions) and openings between the upper chambers of the heart (atrial septal defects).
Researchers analyzed data on 2,525 babies who had heart defects at birth and 3,435 healthy babies born in Baltimore and Washington, D.C., between 1981 and 1989.
Brain function
Smoking during pregnancy can have lifelong effects on your baby's brain. Children of pregnant smokers are especially likely to have learning disorders, behavioral problems, and relatively low IQs. 

drugs and alcohol

  http://youtu.be/KLJQFwQVWbU
Experimentation with alcohol and drugs during adolescence is common.  Unfortunately, teenagers often don't see the link between their actions today and the consequences tomorrow.  They also have a tendency to feel indestructible and immune to the problems that others experience. 
Using alcohol and tobacco at a young age has negative health effects. While some teens will experiment and stop, or continue to use occasionally, without significant problems.  Others will develop a dependency, moving on to more dangerous drugs and causing significant harm to themselves and possibly others. It is difficult to know which teens will experiment and stop and which will develop serious problems.  Teenagers at risk for developing serious alcohol and drug problems include those:
  • with a family history of substance abuse
  • who are depressed
  • who have low self-esteem, and
  • who feel like they don't fit in or are out of the mainstream
Teenagers abuse a variety of drugs, both legal and illegal.  Legally available drugs include alcohol, prescribed medications, inhalants (fumes from glues, aerosols, and solvents) and over-the-counter cough, cold, sleep, and diet medications.  The most commonly used illegal drugs are marijuana (pot), stimulants (cocaine, crack, and speed), LSD, PCP, opiates, heroin, and designer drugs (Ecstasy).  The use of illegal drugs is increasing, especially among young teens.  The average age of first marijuana use is 14, and alcohol use can start before age 12.  The use of marijuana and alcohol in high school has become common.
Drug use is associated with a variety of negative consequences, including increased risk of serious drug use later in life, school failure, and poor judgment which may put teens at risk for accidents, violence, unplanned and unsafe sex, and suicide.
Parents can prevent their children from using drugs by talking to them about drugs, open communication, role modeling, responsible behavior, and recognizing if problems are developing.
Warning signs of teenage alcohol and drug abuse may include:
Physical: Fatigue, repeated health complaints, red and glazed eyes, and a lasting cough.
Emotional: personality change, sudden mood changes, irritability, irresponsible behavior, low self-esteem, poor judgment, depression, and a general lack of interest.
Family: starting arguments, breaking rules, or withdrawing from the family.
School: decreased interest, negative attitude, drop in grades, many absences, truancy, and discipline problems.
Social problems: new friends who are less interested in standard home and school activities, problems with the law, and changes to less conventional styles in dress and music.
Some of the warning signs listed above can also be signs of other problems.  Parents may recognize signs of trouble and possible abuse of alcohol and other drugs with their teenager. If you have concerns you may want to consult a physician to rule out physical causes of the warning signs. This should often be followed or accompanied by a comprehensive evaluation by a child and adolescent psychiatrist or mental health professional.
