I still don't understand why people are so compelled to combine alcohol and opiates. That's a textbook toxicology no-no. Very unfortunate.
The alcohol intensifies the "buzz". It is very possible (and probably likely) that Boogaard had gotten to the point where the oxycodone was ineffective against residual or chronic pain like it used to be - if you take it long enough, it's easy to build up a tolerance to it to the point where the dose that doesn't do a whole lot for you would probably put someone else in a coma.
Speaking as someone who had a history of abusing pills and booze this makes me very sad. It's all fun at the start but very soon the party just isn't good without the combination. Then you're combining at home. The buzz needs to constantly be intensified and soon this happens. Doctors are nothing but pill pushers. I'm talking every doctor. They know what is going on.
Thank god I had people who care about me. In his case he was probably depressed and didn't have enough people close enough to tell it how it needs to be. Too many people probably along for the ride.
... Substitute that with "people have to be a little more responsible and educated individually about what they are putting into their bodies" and I think that would be closer to curing the problem.
Unfortunately, I don't think the public is smart enough to control their intakes. They need to be controlled and so does big pharm and doctors receiving kickbacks for how many prescriptions they write.
