The main point is very little is known about these drugs regarding potential for abuse or potential to cause psychosis or mania. Most of the media reports have proven to be inaccurate or anecdotal from small sample sizes.

Secondly, McAfee has denied any long term use of the drug on Joe Rogans podcast and said his reports were one-off experimentations.

So both of those combined means that saying his use of bath salts is a good indicator that he may have committed the crime is wildly speculative.
