I am a serious DXM fan and it can be dangerous if you take too much like 2 grams or more, it also can be dangerous when you do it often because it causes brain damage although out of all i've read about the brain damage, it is not permanant unless if you OD which can cause a high fever and possibly fry your brain(depending on how much you do). Also there is no evidence of physical dependence caused by DXM use only psychological.
