It is an oval pill, sort of brownish tan color and there is an imprint of a capital mr, then a score, then either 30 or 80, its tough to tell, but I am pretty sure it is a 30, and on the other side there is a capital g on its own. I was told this was a morhine sulphate of some kind but I cannot even find a single pill with an mr on it at all, and I am looking right at it! I have checked almost every site out there and I have had no luck at all finding anything close to this pill!.Somebod please help me, I found this pill on my son and I need to know what it is. Thanks in advance if someone can help. Ilive in canada nd specifically ontario
