The best known effect of marijuana is of course that it gives users a high.  This effect derives from what is the most known compound in the plant, tetrahydrocannabinol (THC).  
Cannabis (cannabis sativa), as we discussed yesterday here, is a variety of hemp, an herb that contains dozens of active compounds.
One of these active compounds is cannabidiol (CBD), which has now been shown to have powerful medicinal effects for many conditions including chronic pain, anxiety, severe epilepsy, and post traumatic stress disorder (PTSD), which we talked about here.

Since most users have traditionally been seeking the mind-altering euphoria THC provides, many plant breeders have in the past developed varieties with less of the non-psychoactive CBD and higher levels of THC.

Little known fact:  Did you know that famed strain Charlotte’s Web was originally called hippie’s disappointment?  That’s because it accidentally was cultivated with incredibly low THC levels.  It’s low THC levels, however, coupled with favorable CBD levels has made it a go-to for parents looking to treat children with cannabis.

As the medicinal properties of cannabis are becoming more well known the leaning towards THC is starting to change because of a growing market for plants with a high CBD content. Laboratories in Israel, for example, have recently introduced a new marijuana strain that contains almost no THC and is intended purely for medicinal use.

How do you grow?  How important are THC levels to you when finding and trying new strains?  Please share with us.  We’d love to hear from you!
