To get specific professional medical evidence, run those searches in magazine databases and in the online PubMed database of medical articles. That is free, as are many of the articles. A free local library card or public local librarian or a college or university librarian can get you free copies of almost any newspaper, magazine, and medical journal articles that are behind a paywall.
If you are worried about bias, check the funding disclosures in the medical journal articles and the background of the researchers. Many studies, especially in Europe, are funded by government agencies and private foundations. Ultimately, the best corrective for bias and error is free minds and open debate.
On the net, if you are honest with yourself, I believe that you will find substantial evidence for marijuana as a cause or major factor in violence, mental illness, and other harms. In fairness, there are contrary arguments and studies, but they seem to be diminishing in number and qualified by acknowledgement of the harms of marijuana for a substantial segment of the population. I believe that a credible case can be made though for regulated medical marijuana, or at least that is what it seemed to me.
"More freedom is always better than less." Where then do you draw the line? Against heroin and fentanyl, I hope? Against the trafficking of children and pedophilia? Against rape? Ringing abstract propositions often fail when put to the tests of experience and reason.
You talk a lot without saying anything of value while making ASSumptions about what information someone you have never met or knows has researched or not.
Then you are arrogant suggesting how and what I should use in a search lololololololol. Pitiful is you.
