Louisiana State Act 159

Signed into law June 28, 2005, and effective August 8, 2005, Louisiana State Act No 159 found in, Louisiana RS 40:989.1, outlawed the cultivation, possession or sale of 40 named plants defined as hallucinogenic in the state of Louisiana, US. House Bill 173 of 2010 further restricted the sale and possession of herbs in the state. However, use of the plants "strictly for aesthetic, landscaping, or decorative purposes" was allowed. The list contained as many as thirty legitimate herbs of commerce which had no hallucinogenic properties. The law was amended in 2015 to allow certain herbs that had been banned by the state to again be sold in dietary supplement products.
