From a purely idealistic point of view, I'd think the following -- note: the world isn't idealistic but too complicated for me to understand. The first argument is a pro free market argument, the second argument is a pro regulated market argument.

So pure right wing capitalists should probably tend to be pro drugs and pro weapons and pro selling everything (maybe a bit more extreme right, I'm bad with political terms). Left wing socialists should be pro regulation and scrutinize weapons and drugs and how it should be sold.

My stance: regulate it. Make sure people can take it, but have a healthcare worker supervise it. And definitely open it up for research, it doesn't make any sense that some drugs are illegal to research. All kinds of dangerous things can be scrutinized under research, yet when it's drugs then somehow it's not possible? It doesn't make sense.

Note: where I'm from socialism means an amazing welfare state like a Scandinavian country.

Note 2: I'm bad with political labels, if I happened to have offended you, I'm sorry.
