I remember reading once about the original C-99 being tested and having 14/14 CBD/THC. I too found it to be very fu ctional cannabis, though definitely producing a clear high.
Personally, I've used/grown sativa hybrids almost exclusively. Since I medicate for pain, siezures, strokes and autism, I've focused on strains which allow me to participate in life. These have been strains which produce a high.
The new CBD rich strains are also mostly inebriating. A lot are heavier indicas. There's a common misconception that THC breaks down into CBD when harvested later. Not only is this incorrect, it leads to very sleepy cannabis from the CBN being produced. I'm sure you'll find heavy CBD strains to be very non-sleepy, when harvested at peak ripeness.
Californee is correct about phenotype and terpene differences. There are other phenos of Canna-Tsu which are inebriating. Look at all of the strains with 14% CBD and 9%THC and you'll find all kinds of inebriation in Indicas, Sativas and Hybrids alike.
I feel safe in saying there are more functional strains of sativa and sativa dominant hybrids than indicas by far. Though the vast majority still have some level of inebriation. It's truly amazing when you begin to experience higher levels of health and functionality, while not having any inebriation to get adjusted to and compensate for. Removes a significant amount of mental overhead.
