Bath salts were literally all the rage last summer, leading to several violent incidents that gained national attention. A recent study claims that the drug could be more addictive than meth, thus making it more dangerous. Tests were conducted on rats, and they worked harder to get to doses of methylenedioxypyrovalerone than they did to methamphetamine—much harder, in fact. The rats pressed a lever 600 times for bath salts, as opposed to just 60 times for meth.
The rats also exhibited some of the same high behavior that humans did, though not as violent. They went towards repeated actions, like one rat who took to "licking the clear plastic walls of its operant chamber" without interruption for extended periods of time.
If you want to compare meth to bath salts, do it from a distance. Stay away from both.
