A newlywed couple who took LSD during a honeymoon hike had to be rescued after the bride reacted badly to the drug.

Police said the 20-year-old bride from Crestwood was airlifted Tuesday to a suburban St. Louis hospital where she was listed in serious condition.

The rescue happened in a conservation area near Fenton.

Investigators say the husband called Tuesday saying his wife of just three days had fallen and hit her head. He later admitted that the two of them had used LSD and she got very sick from it.

Two horseback riders familiar with the area found the couple. One of them said the woman was having seizures.

The husband was taken into custody for alleged drug possession.
