"... that not everyone (including my sister) who starts with pot moves on to hard drugs, it is also true that virtually all hard drug users started with pot."
Substitute the word 'beer' or 'milk' for 'pot', and your above statement is just as true. It's not an argument agaainst legalization.
"That's convoluted logic. Not all people who drank milk or beer become hard drug users. But nearly 100% of hard drug users smoked pot before moving to the hard stuff."
I suppose that in the estimation of the omniscient almighty, we're all idiots. But I still get frustrated when people say stupid things tryinbg to tell me that I'm stupid. Michigander4, can you see what you are doing wrong here?
