A lot of these studies gave their test subjects CBD in dosages of several hundred miligrams at once. In oil form that's often entire bottles ($30-50 per legal product in my jurisdiction). So it's basically financially infeasible for anyone to self-medicate with CBD unless they get it from prescriptions for an actual medically diagnosed condition.
I've tried taking a bottle of CBD oil, which is only a few euros here from the drug store. The main issue is it makes you high in some way, so definitely not without side effects. No idea how they work around that.
