Well, yes, I can sort of see the idea:

Channel 4 has caused controversy after inviting journalists to take drugs and alcohol for a documentary.

The
publicly-owned station, which is at the centre of the scandal about
premium rate competitions, has asked an independent production company
to develop the programme after a report in March listed alcohol as more
harmful than cannabis and ecstasy.

The company,
Ricochet, has written to prospective participants inviting them to
spend a month in Holland where they would take drugs and drink alcohol
"with no legal repercussions".

But I’m not sure why Holland. Given the output of most journalists, surely most are stoned, drunk or high anyway, aren’t they? So one could reduce costs simply by studying them in situ?
