The United States is ahead of its time in legalization. So I can see how more conversive countries have not allowed it yet. But hopefully that will change in the following years.

Just below 2014 there was no legislation in the United States for Cannabis and before 1996 you could not even get it medically.

So give it a few years and maybe even where you live may have it.. Go look at Thailand, they are booming with it now.
