Moderation is not that hard, unless you have personal issues. What's wrong with this?
I'm sure every drug addict never decided to be an addict to begin with.
These people were messed up to begin with. Or uneducated (ie taking too much)
That sounds like an uneducated comment.
It's not hard to moderate dosage and frequency when it comes to drugs. With all the info of the internet
I guess it'd depend on which drug we're talking about -though obviously, I don't give a shit what you do. Go ahead and break out the moderately-sized case of needles.
I'd be surprised if there were any cases of people regularly altering their mood/mind with drugs who didn't have severe internal conflict, though. I'd guess the real concern, if it were a party I'm concerned with, would be whether or not they're happy, since regularly altering their mood would seem to indicate they aren't. It'd be particularly concerning if it were an addictive drug where a tolerance can be built up with "moderate" use.
