Hi Crazy guy, welcome.

I think what you're talking about here is quite obvious. Also, I highly doubt that anyone here is making spice that is only 50% pure. That would imply that something has gone wrong in the extraction. I'd be suspicious as to the what constitutes the other 50%. Furthermore, dosage is dependant on the maker and the user too. One probably has to experiment to find full satisfaction. One man's "too strong" is another man's "too weak", and you're probably better off just sticking to what works
