Inetersting note:
Stronger opiates tend to ruin the high from less powerful ones.
Example:
When I was using frequently, I could get a nice high from 80mg oxycodone. So, I figure, 100mg hydrocodone would be an equivalent dosage. I got the buzz but no euphoria. Now before using the oxycodone I could get the same euphoria from hydrocodone but once I moved to the stroger opiate the lesser did not provide the same high any longer. I took time off of all opiates and was able to regain the feeling of euphoria from the hydrocodone at a significantly lower dose.
