Re: altered state of consciousness

I've used animal dewormers (Pyrantel Pamoate paste, Exodus, Safeguard (fenbendazole), Valbazen, Equimax, etc.) with good success and have no issue with them.  They're basically the same product/drug in a paste or suspension.  I was initially reluctant for the same reasons you are, most likely, but eventually accepted that the drugs were the same and that the risk was low, in any case. 

I found that asking this question helped:  would they give extremely expensive race horses (or any farm animal, or pet) a product that's likely to harm them?  The answer, for me, was 'probably not'; there's nothing to gain by doing that.
