A drug, thought by many to be long gone, appears to be making a massive comeback in Georgia.

Statistics from the Georgia Bureau of Investigations show the number of LSD submissions to the GBI crime lab have increased by more than 500 percent since 2014 -- from 21 in 2014 to a whopping 137 in the fiscal year 2017.

"We don't know why (the numbers are) growing, but we are monitoring the trend," said GBI spokeswoman, Nelly Miles

Miles told 11Alive's Ryan Kruger she was inspired to look into the number of LSD cases after a recent case in Jones County, about 90 miles southeast of Atlanta.

Last week, 11Alive's sister station 13 WMAZ in Macon reported two students were hospitalized within 24 hours, after possibly taking LSD. The Jones County Sheriff's Office posted a photo on Facebook of the paper the students ingested with a warning to parents.

Five people were soon arrested, two of the five were under the age of 18. Authorities believe they were selling the drugs to high school and college-age students.

"It's extremely dangerous, it puts people in an extremely altered sense of reality," said Lt. Michael Kenirey with the Bibb County Sheriff's Office.

In some instances, authorities say the drug user can become incredibly violent.

In April, Athens-Clarke County Police arrested 21-year-old Adam Presley. Authorities say Presley stabbed multiple people while high on LSD. He was found naked inside of a Walmart with blood on him.

While the GBI's Miles says the state hasn't seen an increase in deaths related to LSD, the number of cases in the state has the attention of many in law enforcement.
