The problem with the drug legalisation idea is that it is controversial. Even here in the UK - home to more narcotics-based pop culture movements than anyone sane can really stand - most 'soft' drugs have not been legalised, and I can see large sections of BiH society (ironically, cross-entity!) being dead set against it.
This could change in 20 years or so, but by then any first-mover advantage would have been lost.
Lot's of controversial ideas are ultimately embraced.
I don't think the state (through force) ought to make that decision for me or anyone else. Just as they have no right to tell me what may come out of my mouth, similarly they shouldn't have the right to tell me what to put into it.
Keeping pot illegal is a sure way to guarantee a corrupt police force, narco-bosses, high crime rates, people who have harmed nobody in jail for years at taxpayer's expense and the usual bureaucratic/ government corruption - mishandling, petty interest group lobbies, misapplication of resources and general destruction of other people's money whilst doing more harm than good. Not to mention bankrupting the economy of the society in question in the process with idiotic laws that seek to change the nature of man by force.
How about personal responsibility and freedom? To chose what you ingest into your own body, if there is one thing in this world that we own, it's our body. There are drug addicts, alcoholics, porn addicts, skydivers, base jumpers, X-games participants and what have you, you can't legislate stupidity, and all attempts have failed miserably.
The same argument can be made for government bans on trans-fats, subsidies of corn, milk or what have you, their proposed higher taxes on sweet soft drinks and fast food chains. Because, you know, they know better than us so they should control our behaviour ever more, for our own good.
Banning or restricting cars on certain days of the week is an idea that has been tried successfully in a number of places, though. Can't see why it wouldn't work in Sarajevo. Ditto renewable energy, which can be generated even at the micro level.
More needless government intervention and attempts to control people's lives and livelihoods through central planning and compliance through the threat of force.
This has been tried in this region for over 70 years, and look at the results.
Why not try freedom for a change.
The best way to help BiH is to drastically reduce the role of government, de-centalise the power structure, drastically cut government spending, hold governments responsible for overspending, drastically cut the ridiculous taxes that fund the corrupt machine and make it easy for business owners to set up shop and offer their good or service in a free market
Selling pot? Why not, it's an industry and a lucrative one. If you think it's harmful, choose not to take it. If you can convince enough people of the harm, you don't need the government to use force on your behalf. Your ideas should be persuasive enough, if you truly believe in your own set of principles, that is.
But this undermines political power and influence. They don't want a marketplace of ideas, they don't want you thinking on your own or making decisions for yourself. So we won't be seeing these economic reforms whilst former socialist/collectivists are still running the show and still thinking they know what's good for us, or else!
