It's better to do the Robitussin Maximum Strength cough syrup because coricidin has other active ingerdiants in it that can actually kill CERTAIN people with CERTAIN probles, ( like metal instabilities) Try to find something with just Dextrothrophanhydrophabmide as the active ingrediant Because thats the only thing in there thats going to make you trip balls!! Hope you have fun when you try this!!
