• The incidence of genital warts declined by more than 90% in adolescent and teenage girls in the first 4 to 5 years after introduction of the human papillomavirus (HPV) vaccine in Australia.
• Note that the reductions in wart incidence among girls and women were accompanied by 50% to 80% decreases in the incidence of genital warts among heterosexual boys and young men although no decline in wart frequency was seen in heterosexual women or men older than 30.

The incidence of genital warts declined by more than 90% in adolescent and teenage girls in the first 4 to 5 years after introduction of the human papillomavirus (HPV) vaccine in Australia, investigators reported.

Genital warts occurred more than 70% less often among women 21 to 30, as compared with the 3 to 4 years before the vaccine became available. The reductions in wart incidence among girls and women were accompanied by 50% to 80% decreases in the incidence of genital warts among heterosexual boys and young men.

No decline in wart frequency was seen in heterosexual women or men older than 30, Basil Donovan, MD, of the University of New South Wales in Sydney, and co-authors reported online in BMJ.

“In 2011 no genital wart diagnoses were made among 235 women under 21 years of age who reported prior human papillomavirus vaccination,” the authors noted. “The significant declines in the proportion of young women found to have genital warts and the absence of genital warts in vaccinated women in 2011 suggests that the human papillomavirus vaccine has high efficacy outside the trial setting. Large declines in diagnoses of genital warts in heterosexual men are probably due to herd immunity.”

The study provided a glimpse of the impact of HPV vaccination in a real-world community setting as opposed to a clinical trial.

“It actually generated data consistent with what we hoped and predicted would happen,” said Greg Poland, MD, of Mayo Clinic in Rochester, Minn. “It showed in a large study that [the vaccine] worked and it worked fabulously.”

Marijuana Use Increases Psychosis Risk

Marijuana Use Increases Psychosis Risk

Well folks, here it is again. Yet more studies that conclusively demonstrate that SMOKING MARIJUANA IS BAD FOR YOU!!

Regular readers of my blog will have already read the other numerous scientific studies about which I have previously written.

Here are two more studies – one involving 20,000 people with psychotic illness, and another involving 1,923 people ages 14-24 over a period of 10 years.

Dutch researchers led by Jim van Os from Maastricht University conducted the decade-long youth study in Germany and ruled out those that presently smoked marijuana and those with pre-existing psychosis. They found that new marijuana use doubled the risk of new psychotic symptoms, even after accounting for age, sex, socio-economic status, other drug use and other psychiatric disorders.

Dr Matthew Large, from Australia’s University of New South Wale’s School of Psychiatry and Prince of Wales Hospital worked in partnership with Melbourne, Australia’s St. Vincent’s Hospital and the U.S.’s George Washington University School of Medicine and Health Sciences, pooled patient data from more than 80 studies which had probed the link between psychotic illness and substance abuse. Previous studies had examined the role of marijuana, alcohol and other psychoactive substances, but this new study examined marijuana alone. They found that most of the schizophrenic patients had been marijuana smokers, and of those who had been, the onset of mental illness occurred 2.7 years earlier.

Addendum: 5/5/14 – The reader should note that the majority of all such research upon the long-term, or delayed effects of marijuana usage has been focused upon the immature (and therefore, not-fully-developed) brain. Most researchers have concluded that the human brain reaches full maturity around age 25. The greatest risks for psychoses in later life is experienced when the immature brain is exposed to cannabis.

Smoking pot may hasten onset of mental illness

NEW YORK (Reuters Health) – Smoking marijuana has been linked with an increased risk of mental illness, and now researchers say that when pot smokers do become mentally ill, the disease starts earlier than it would if they didn’t smoke pot.
