What is THC, CBD and CBN?
Marijuana Chemistry, Excerpted from Section One, Indoor Marijuana Horticulture, The Indoor Bible
Cannabis is the only plant that produces chemicals called cannabinoids,
however, with gene splicing and genetic engineering, it is only a matter
of time until cannabinoids are added to other plants. Cannabinoids are
ingredients unique to cannabis; the psychoactive cannabinoids are
responsible for the mind-bending effects of marijuana. Some cannabinoids
get you high. Around 40 cannabinoids have been confirmed to exist, but
most are not psychoactive. Here is a short rundown on the six most
prominent cannabinoids.
D9 THC, the main ingredient that gets you high, is called:
D9-trans-tetrahydrocannabinol. All cannabis, whether industrial hemp or
drug marijuana, contains some D9 THC. Industrial hemp cannabis contains
infinitesimal amounts while dried flower tops (buds) of potent marijuana
can contain up to 25 percent D9 THC. In potent varieties of marijuana,
perhaps all of the mind-bending effects are derived from D9 THC.
D8 THC is found in very low concentrations in cannabis. It also gets you
high, but there is so little D8 THC in most cannabis that researchers,
breeders and growers concentrate on the more abundant and potent D9 THC.
To simplify matters we will refer to both D9 THC and D8 THC as THC.
Cannabidiol, known as CBD, also appears in virtually all varieties of
cannabis. The amount of CBD varies enormously, from a trace to more than
95 percent of all cannabinoids present in a plant. CBD generally has a
sedative effect regarding the high you experience. CBD, when combined
with THC, tends to postpone the beginning of the high, but, the good
part is that CBD can make it last twice as long. Whether CBD increases
or decreases the force of the high is subjective and must be discerned
by each smoker.
Cannabinol, or CBN, is produced as THC oxidizes or degrades. Only a
trace of CBN exists in fresh bud. Stored and cured tops or hashish have
higher levels of CBN, that has converted from THC. Marijuana with high
levels of CBN generally make the toker feel disoriented and often sleepy
or groggy, often referred to as a stupefying high. At best CBN contains
only 10 percent of the psychoactive potency of the original THC.
Tetrahydrocnnabivarin, called THCV, is the shorter three-carbon propyl
that replaces the five-carbon pentyl chain. This compound is associated
with the fragrance of the plant. In other words, very pungent smelling
marijuana normally contains THCV. Warmer temperatures bring out more
smell. THCV is found in very potent marijuana that originated in
Southeast and Central Asia as well as regions in Africa. Concentrations
of THCV usually make the high come on quicker and disappear sooner.
There is still much research to do on this cannabinoid.
Cannabichromene, or CBC, may make up to 20 percent of the cannabinoid
profile in a plant. Little study has been done on this cannabinoid. So
far, researchers believe that it may interact with THC to make the high
more intense.
