A synthetic form of speed that's sold as a bath salt is causing disturbing side effects. Users experience hallucinations, agitation, chest pain and paranoia. Tom Parker, with the Oregon Partnership, says it couldn't be used as a bath salt.  It's also sold as stain cleaner, plant food fertilizer, and insect repellant. Louisiana is the first state to ban it. The Oregon Pharmacy Board plans to take action in April. Washington currently does not have plans to ban the substance.
