Resolved Question: Drugs: Pot, is it really OK? What about other drugs like cocaine, shrooms, extacy?

So, I don’t do any drugs (other than drink alcohol sometimes). I started dating someone who smoked pot daily–this was a problem but soon I got used to this mostly because 1) I couldn’t really tell the difference when the person was high, 2) I started reading about it and found out that most of the things I thought were true about pot (addiction, etc) were not really true. Or at least not in the people around me. Also, I live in a city where everyone does it. Things were fine, except that this person also does other recreational drugs from time to time. I have tried to be ‘open minded’ about this but I just can’t really believe that its OK to do these drugs even ‘occasionally’. Am I overreacting?
