Scotland is also tied for the highest rate of cocaine use per capita in the world. This is because cocaine goes well with bullshitting and alcohol
but Scots have a predisposition towards opiates. The climate is cold wet and barren, chokes you and chills you to the bone. If you live in the city you party every weekend and if you live elsewhere you just want to kill your pain. Scots aren't fake sociable people who have a ton of stuff to do, their whole country has a historic alcohol problem so of course they like new depressants. Scots are also known for being foolhardy and reckless and my ancestors were basically slaughtered for their own naivete and having far too huge balls.
Scots have the highest number of drug deaths because they're alcoholic poets with huge balls and problems with depression they solve with other depressants
