My understanding is that that attacker wasn't using bath salts, and that the connection to bath salts was all speculation.

Also, I think bath salts is usually synthetic cathinones, i.e. functional analogues of khat, and not derivatives of meth, cocaine, ecstasy, or pcp.

Could be wrong, I'm just some guy on the internet.
