Does the combination of DXM and CPM create a more psychoactive effect than other DXM products. Cause I noticed that I get more messed up off of CCC's than Musinex or Robo's. One box of CCC"S is only 480 mlg of DXM and a box of Musinex (generic and non generic) contains 600 mlg. But yet CCC's effect me for than Musinex. So im wondering does anybody know if CPM plays a roll in the high other than being toxic in high doses?
