20 years ago he would have been around 30, which isn't quite the same as someone trying drugs as a teenager or student.
How old are you?
Also, I can certainly see situations where somebody in their 30's might just try something, should the opportunity arise, that they didnt have an opportunity to experience in an earlier life.
This, is not, in itself, a legitimate criticism.
Hell, 15 years ago or so I went to a lap dance club (Part of somebody elses stag night)
It was an interesting experience but not one I have any interest in repeating.
Dont really see the attraction really.
I have also smoked tobacco in various froms too.
Don't see the attraction for that either
I may not like the guy myself as a potential PM is neither here nor there. The fact hat he snorted a bit of coke 20 years ago is utterly irrelevent.
