Really there are no side effects, but if you are particularly sensitive to some of the mixture of the CBD/THC, you can feel lethargic or excitability. For CBD to work properly, you need a very small amount of THC. Good extractors can get this nailed down, but I've had some that clearly did not get it right.
Terpenes are all the rage and they each add the unique flavor and taste, but what has been found is that each has additional health benefits. For instance, Myrcene is a terpene with a strong "earthy" taste and found in most all indicas. It is partially responsible for the lazy, relaxed feel an indica provides. On the other hand Caryophyllene is found in more sativa strains and helps with depression, and helps provide some energy benefits.
I have a few friends with extract kitchens that are really concentrating (no pun) on these areas.
