I've never heard that alcoholism is more rampant in cold climates than it is in warm climates. What I do know? Is that drug abuse, and alcohol abuse, mirror more closely to economic opportunity; it is a form of self-medication, as folks need a sense of purpose and a reason to get out of bed in the morning. It is self-medication for depression when folks have no purpose or self-esteem, nothing to do with. . . . "the weather."

Or, when folks have no sense of fulfillment or real faith in the career that they ARE doing.
Most intelligent folks know, the economic opportunities have tended to, in the late last century, to follow the sun. So, that may be the cause of your ignorance.
Now, if you have any. . uh, links to prove otherwise? Sure, post that shit up.
I seriously doubt, a person that loves their job, their family, their friends, and has a fulfilling life, is going to become an alcoholic or dope fiend. . . just because of a little cold.
That is the dumbest, most ignorant thing I have ever heard.
