If anyone ever decided to experiment with Robitussin (dextromethorphan - DXM) I would really do some detailed research, as this is a substance with a low OD (LD50) level. It's also a substance which in some forms (coricidin etc) can and has killed due to other active ingredients added to stop abuse.
There is also a lot of circumstantial evidence (nothing concrete yet as these substances have only really been taken recreationally quite recently) that DXM (and it's family of drugs) can cause lesions in the brain (http://en.wikipedia.org/wiki/Olney's_lesions). These have only been found in animal studies so far, but it at least should make one cautious.
For those not familiar with this drug, it's in the family of drugs known as dissociative anaesthetics (i.e. ketamine, PCP etc), and shuts out external sensory perception. So if you take enough not to knock you out, you might have interesting experiences. But if you take too much, then...
Yes, this might sound negative and serious, but this is a family of drugs which should really be treated carefully. Also, there is a large percentage of the worlds population who are CYP2D6 enzyme deficient. Such people would have very severe effects to even minute amounts of this substance.
