yes it will work(to my knowledge). they say that, I believe, to try and get people not to use it recreationally. the hbr is part of the DXM. it stands for Dextromethorphan Hybromide. Don't know how long they will take to kick in. When drinking the syrup, it has taken about an hour or so for the initial effects. Dont expect anything before an hour or two. I think gelcaps take longer to work. Could be wrong though, never tried the caps.

DXM help please Ok im going to be doing some dxm with my friend and we bought 2 bottles of 20 robotussin with only dxm in it, the problem is (this might sound dumb) but it says dextromethorphan or whatever then after it it says HBr......and on the front of the bottle it says non narcotic, will these work? if so how many should we take, we both weigh around 145. also i was wondering about how long they will take to kick in. thanks Rating: 5
