Some call it an herb and others a drug, but in reality it's a combination of both and it's entirely legal.

But as salvia divinorum continues to gain popularity, some of Wisconsin's lawmakers want to make it illegal.

The drug can be bought at stores in Northcentral Wisconsin, including one in Wausau that sells it for between $15 and $20 a gram depending on the strength.

When smoked or chewed, salvia can cause short, but extremely intense hallucinations, but that's not the sole reason a bill to ban it has been introduced.

Some say the drug is not only accessible, but appealing to children and teens.

"Initially two years ago there was a lot of information saying that this is the newest hallucinogenic, saying that it's safe because it's an herb," says Sue Nowak, a certified prevention specialist. "They kind of looked at it as a cross between using ecstacy and acid."

If the bill passes, even possession of salvia would be illegal and law enforcement could test people's systems for the substance if need be.

The drug is legal in 45 states; Delaware, Louisiana, Missouri, Tennessee and Oklahoma are the exceptions.

The bill introduced in Wisconsin has been referred to a committee on criminal justice.

If approved, it will move on to the Assembly.
