NASHVILLE (AP) - Proposals that increase penalties for making or selling imitation drugs are headed to the governor for his signature.

Both proposals, which are similar, unanimously passed the Senate on Wednesday. The measures, which are part of Gov. Bill Haslam's crime package, were also unanimously approved in the House.

One imitation drug authorities are trying to crack down on is called bath salts.

Sponsors say the drug is not marketed for ingestion and can be purchased in convenience and tobacco stores.

The bills would allow authorities to declare the stores where the drugs are sold as public nuisances.
