The owners of Super Gas have been indicted for selling synthetic drugs to an undercover agent, something their attorney says they did not realize was illegal to sell.The defendants, Paresh J. Patel and Bhavana P. Patel, both entered not guilty pleas before Circuit Court Judge Bart Stanley to charges of distributing and possessing a synthetic cannabinoid and possession and delivery of drug paraphernalia.Their charges come after lawmen sent an undercover agent into numerous stores around Warren County attempting to purchase items which had been made illegal this summer. The items they were looking to buy were certain types of plant food and incense which have been widely used as intoxicants. The wide abuse of the items prompted the state legislature to declare the items illegal for sale or possession in Tennessee.
