I am from Spain. What are you talking about? Everything you just listed is not only illegal, but very illegal, considered hard drugs by the vast majority of the population, and will get you jail time if you're trafficking or even just possessing low quantities of it if you have previous legal convictions (not even drug related ones, any previous convictions!). And you can get them "everywhere"? lol
I am often amazed with the matter-of-fact tone that is frequently used on this site to speak about certain topics while being 100% wrong about them. The scary thing is, if I wasn't from Spain, I might've read your post and believed it. Makes me wonder.
