What are the other risks of using synthetic cathinones ("bath salts")?

Another danger of "bath salts" is that they might contain other ingredients that cause their own harmful effects. There is no way to know what is in a dose of bath salts other than testing it in a lab.

In turn, there have been reports of other drugs containing bath salts. For example, hundreds of ecstasy capsules tested in two South Florida crime labs in 2012 contained methylone, a dangerous synthetic cathinone.
