Demi Moore’s frantic 9-1-1 phone call has shed more light on the night she had a seizure and was rushed to the hospital, and it may have also revealed the substance that she was smoking.
As RadarOnline.com previously reported, a friend of Moore’s can be heard on the call explaining to the operator: “She smoked something, it’s not marijuana, it’s similar to incense. She seems to be having convulsions.”
A likely possibility is that Demi was smoking
K2 Spice, a “currently legal herbal incense product spiked with powerful designer drugs” that don't show up in tests, according to WebMD.
RadarOnline.com spoke with addictions specialist Dr. Phil Dembo, who said judging by the description on the 911 call, he believes Moore was smoking K2 Spice, which is currently legal in the U.S. but under investigation by the Drug Enforcement Agency.
Dr. Dembo said Demi’s convulsions could have been a result of smoking the substance.
