ABSTRACT

A hemp oil product (Hemp Liquid Gold) was purchased from a specialty food store. Fifteen milliliters was consumed by seven adult volunteers. Urine samples were taken from the subjects before ingestion and at 8, 24, and 48 h after the dose was taken. All specimens were screened by enzyme immunoassay with SYVA EMIT II THC 20, THC 50, and THC 100 kits. The tetrahydrocannabinol carboxylic acid (THCA) concentration was determined on all samples by gas chromatography-mass spectrometry (GC-MS) (5). A total of 18 postingestion samples were submitted. Fourteen of the samples screened above the 20-ng cutoff, seven were above the 50-ng cutoff, and two screened greater than the 100-ng cutoff. All of the postingestion samples showed the presence of THCA by GC-MS.
