I paid over £100 for a return flight to Leeds;

it was to be a medical guinea pig for 2 weeks.

So I have given up for 2 weeks, had 2 joints and give up for a further month now, I could get a new appointment with a company in Manchester but I don't fancy risking it.

The nurse that was testing me explained that you would fail it even if you had been in the presence of others smoking it.
