to think that 8.30 am is too early to skin up

[drwitch]

it seems to be getting more and more common round us (dads doing it while walking their children to school, people doing it before opening up their shops for day)

I am just really surprised that it is done so much in public

I don't actually drink coffee, red bull, alcohol or smoke any form of cannabis or tobacco. This either means I'm an impartial judge, or speaking ignorant nonsense.

you decide.

However, from extensive observation (family, flatmates, etc), I would say the following affect judgment and behaviour, and I would not allow someone to look after my children while under their influence:
Alcohol,
Cannabis.

My only concerns about cigarettes are the second- and third-hand smoke. My mother-in-law supervises my children while highly-caffeinated, shortly after having had a fag (outside) frequently.

I cannot, in good conscience, make any comments whatsoever about Red Bull, because I haven't had the chance to live with several people who drank it, so I have hardly any anecdata.
