I just bought some medicines for my cold/flu needs at the local CVS Pharmacy.
I got the generic for Robitussin DM and the generic for Mucinex.
Now, I totally understand that Robitussin DM has dextromethorphan in it, and is a drug of abuse.
However, the pharmacy employee said specifically that I was getting carded because of the guaifenesin.
As far as I can tell, guaf has no psychoactive effects, and does nothing that would be of any use to drug abusers… unless they had a cold or flu.
So, was she perhaps lying or mistaken, or is there some reason to worry about guaifenesin abuse?
