An article about marijuana published on CNN.com today contradicts itself several times, and in the end admits the researchers were paid by anti marijuana organizations and Big Pharma. Articles like this do not provide any useful information, and are used to instill fear and propaganda. The following quotes are from the same article!
" Using marijuana seems to increase the chance of becoming psychotic..."
" The researchers said they couldn't prove that marijuana use itself increases the risk of psychosis..."
"We've reached the end of the road with these kinds of studies," said Dr. Robin Murray of King's College, who had no role in the Lancet study. "Experts are now agreed on the connection between cannabis and psychoses. What we need now is for 14-year-olds to know it."
" Two of the authors of the study were invited experts on the Advisory Council on the Misuse of Drugs Cannabis Review in 2005. Several authors reported being paid to attend drug company-sponsored meetings related to marijuana, and one received consulting fees from companies that make antipsychotic medications."
