There was this article about Iceland combatting teen drug abuse by providing alternative activities and social outlets:

Iceland isn’t really a poor country though, even if it doesn’t have a high GDP. It’s more like New Zealand.

cite for what? my comment is basically asking for a citation for the OP's (and your) claim that substance abuse isn't culturally dependent?

I didn't claim that it wasn't culturally-dependent. Both people turning to drugs to self-medicate, and people not supporting and funding effective interventions - people on both sides rejecting or not seeing the opportunity to engage in community-building - is absolutely a culture issue.
