Kentucky lawmakers appear ready to crackdown on stimulants called “bath salts,” that are being sold in many gas stations and convenience stores across the commonwealth.Dr. Henry Spiller of the Kentucky Regional Poison Center in Louisville says the salts contain stimulants that users snort, inject and smoke.“They appear to use it because there’s a short duration of the drug, we think of about four hours," he says. "And at the end of the drug use, there’s a period of down. And they use it again and after 12, 16, 18 hours of this is when they sort of get to this delusional state.”Legislation banning the possession, trafficking or manufacture of the products, which have the street name dove, easily cleared the House Judiciary Committee and awaits a House floor vote.
