I dont get your obsession with alcohol.
Let me just explain to you, why, in political terms, its an irrelevant issue.
No politician wants to be the one who legalises any drug, and then has to justify that decision to grieving mums who've just had to bury their children due to contamination, overdoses allergic reactions etc, etc, etc.
Alcohol however, is already deeply ingrained in our society (for good or bad) and is therefore not a big political issue, as in no one has to account for its availability, or take any blame when someone dies, or kills, or ruins lives due to its missuse.
In short, we can debate the topic of drug reform for years, but major reform will NEVER happen, as implementing it will be instant political suicide for any individual or party trying it, and the first death caused by a newly legalised drug would end up in a massive legal claim.
