I think the lifestyle in Spain probably does away the need for thearapy in both adults and children.
Although many expats do tend to find comfort in the form of the bottle.
Spanish culture tends to make Spanish children harder in my experience, they tend to face problems in a relaxed manner and frankly in the south most kids so relaxed there horizontal.
I could be wrong, but children of our friends and our`s seem to approach growing pressure`s differently.
But cannabis is a big problem amongst teenager’s.
As for Expats, the few we no with teenager`s haven`t any issue`s, i`m not sure if there are that many expats with kids in the age group between 9-18 yrs, it would be very irresponsible to move to any country with children that age.
