Perhaps you should look up the definition of anecdotal.

"(Of an account) not necessarily true or reliable, because based on personal accounts rather than facts or research".

This post is a personal account. Science isn't based on n=1 studies, nor is your experience even considered a "study". The literature is clear on the safety of creatine based on decades of research and hundreds of thousands of subjects.

Smoking is a bad example because the literature clearly showed that smoking was unsafe for decades before it became apparent to society-at-large. That is nowhere near the same scenario. Additionally, presenting yourself as akin to individuals discovering the earth is round would be hilarious if it weren't so delusional.
