Choose your poison
Here's an interesting site about opioids and related issues and problems.
I don't think that there's any such thing as a "harmless drug", no matter what some cannabis promoters claim. Just like there's no such thing as a "harmless knife".
But it's also clear to me that there is mostly money and politics behind drug laws. Just look at the fact that two of the most damaging and lethal of drugs, tobacco and alcohol, are also the two which are legal everywhere. How does that make sense?
