Science is science. The studies you cite prove nothing. Play your immature word games all you want.
Study exposes mental effects of pot
According to the New Scientist, there was hardly enough reliable evidence to support the idea that cannabis use could cause such mental illnesses until now. The lack of good evidence has delayed studies in finding harmful effects of a seemingly harmless drug.
One of the main conclusions of the research was that people who start smoking cannabis as young adults were at the greatest risk of later developing mental health problems. Another study done by an associated team concluded that depression and schizophrenia in the United Kingdom's population could be reduced by 13 percent if marijuana use was eradicated.
They concluded that regular marijuana use led to educational failure and unemployment, which could increase the risk of depression.
Researchers at King's College London, UK, analyzed continuous data taken on over 1000 people born in Dunedin, New Zealand in 1972 and 1973, and found that people who used cannabis by age 16 were four times as likely to have a diagnosis of schizophreniform disorder (a milder version of schizophrenia) at age 27 than those who didn't use the drug.
Another study done to see the drug's effects on the lungs was coupled with research done on the long-term mental effects of cannabis usage. According to the New Scientist, The British Lung Council concluded in a recent study that smoking marijuana was as bad if not worse than smoking cigarettes.
Furthermore, the cannabis produced and harvested now had been proven to be 10 to 12 times stronger than the trees smoked in the "flower-power' generation
By further examining marijuana joints, the scientists found that the tar from a joint contains concentrations of carcinogens benzathracenes and benzpyrenes up to 50 percent higher than tobacco smoke, and that THC, which is the most concentrated psychoactive ingredient of cannabis, destroys the immune system cells that help protect the lungs from infection.
