G. Edward Griffen wrote a vitamin B17 book, "A World Without Cancer", in 1974.

Also, fuck all these goddamn "anti-depressant" POISONS the corporatocracy is pushing on us without adequate disclosure under the blind-faith religion of unverifiable SCIENTISM.

Ketamine has been around for decades. Sure it can be a fun party drug like alcohol and you can do so much until you pass out. But ketamine is FAAAAR safer than alcohol. Furthermore is the only think that actually works for many people with chronic depression. But Big Pharma can't make a profit from it. Nonetheless independent clinics to treat depression are open in the USA, UK, and Australia. Meanwhile Canada FINALLY has a couple now but they're not accessible to everyone, are ridik expensive, and impossible for someone who's life was ruined by 5 years on their "anti-depression" poison with no discernible scientific process nor safety precautions. In Canada you're better off buying illegal ketamine with Bitcoin on Tor authentic free-markets (where the quality is usually superior) than paying $3K plus travel expenses to a clinic.

Do your own research before you do anything rash. I'm not saying you should go and commit any crimes of a corrupt police state, like any above or guillotining your local corrupted government (but I'm not not saying it either).
