You have little to no experience of it yet your instantly opposed to it ?
Your last drinking experience was when u were 13 ??
I drink with my friends quite regularly, we don't get f@$ked up drunk or anything like that, just conversation over some beers
more often than not the conversation flows like the alcohol.
What u need to do is pick who you drink with a bit more carefully.
As far as drugs go how can a stoner be violent ?? All the ones i know are the nicest kindest most relaxed people u will come across.
but
heroin = scum
ice = scum
and all the others excluding pingers are just for bogans,
But seriously if your happy not doing it then thats fine its ur loss but i do strongly feel like you are missing out
