Okay, so like, taking the word "need" out, it still stands. Why are mind-altering drugs/alcohol "fun"? Like, I don't get the appeal of not being in control.
Some people do indeed lose control when they drink or take drugs, and some people just don't like it. Those people are probably better off without it. However, many people don't lose control and enjoy it occasionally.
It can be incredibly fun. I was walking in the woods near my house with my friends one night on LSD, and it was like a whole new world. Looking back at my area from the top of a hill through the woods, it looked like a huge town all up the side of a really tall hill. At one point, me and my friend looked up at the clouds, and all of the clouds were rushing in towards a central point and wooshing up in a big vortex into the sky really fast above us - I'd never seen anything like it. I was once at a festival, and sat in a big tent, and for a moment, me and my friend both thought that we had shrunk really small and everything else around use was really big. There was once this pinky-purple fuzzy layer about a centimetre thick around everything in my garden - even over my friend. It was the most surreal thing. There'll be moments, someone will say a funny sounding word, and everyone will just crease up in laughter.
I, personally, call that a whole lot of fun.
I'd also like to reiterate that I don't have a problem which other's choice to not like it, or simply not want to try it. I just honestly believe that the social stigma surrounding many hallucinogenics is gravely misplaced - and that frustrates. All evidence and research comes to the same conclusion as I.
I apologise if I got a bit intense at times. But you know, considering I feel strongly about this subject, and that it's a controversial subject. I'd say I've remained pretty civil. Just think of the comments section on a political post on Facebook.
