If the gov. tells us not to do something, what is our reaction?
Mine is to ask why it is banned. If it's not a good reason and I can hide my violation of it, providing I like doing it so much, then I might do it.
Do you think that illegal activity comes to people's attention more than legal activity?
It's legal in Holland so no one cares and the activity does not get reported.
It's illegal here so everyone cares so the activity is reported and inflated by the media.
Drug busts get reported and used in research, but maybe legal use doesn't get used in research.
I would think that it's much harder to gather such info in Holland compared to the USA where we have FBI crime stats taken from reported criminal activity.
What types of measurements did researchers use? It makes a huge difference.
