Δ9-Tetrahydrocannabinol (THC)
is the main psychoactive compound present in marijuana. THC can
also be found, as a contaminant, in some commercially available
hemp products marketed in health food stores and on the internet
as a good source of essential fatty acids. The products range
from oil to alcoholic beverages to nutritional bars to candies,
with oil being the most popular and commonly available. The analytical
results are separated into two groups, products tested prior
to and after publication of 21 CFR Part 1308, “clarification
of listing of tetrahydrocannabinols.” The data presented
are a summary of 79 different hemp products tested for THC. THC
was separated by a liquid–liquid or solid–liquid
extraction, depending upon the product matrix. THC concentrations
range from none detected to 117.5 µg THC/g material. Typical
limits of detection for the assay (depending on matrix) are 1.0–2.5 µg
THC/g material. Products that were of aqueous base (beer, tea)
had much lower limits of detection (2.5 ng/mL). No THC was detected
in 58% of the products from group 1 and 86% of the products from
group 2. The amounts indicate that THC levels in currently marketed
hemp products are significantly lower than in those products
available before 2003 and reported in previous studies. The results
reported here may be used as a general guideline for the THC
content of hemp products recently found in the marketplace today.
