LSD impairs your ability to feel cold. People have died by taking drugs and then going out into snow. I sadly can't find the proof to back up my claim, but I read about a case of a girl taking ketamine and then going outside and succumbing to hypothermia.
Here's another case of someone dying from drugs: http://en.wikipedia.org/wiki/D._M._Turner
Turner died after injecting an unknown quantity of ketamine while in a bathtub, presumably drowning while incapacitated by the effects of the drug.
Before jumping down my throat that ketamine isn't related to LSD in any way, I know. It's true. But when you get into a mindset where taking LSD seems like a good idea, taking other drugs starts to seem like maybe-okay. It's no coincidence that the psychonaut I linked to was taking a ton of different drugs including LSD.
I know people are going to be upset with me sweeping LSD under the classification of "drugs." People die from heroin and other hard drugs, but nobody has ever died from an LSD overdose. But I'm not talking about that. I'm talking about the mindset that you're tempted to get once you delve into this scene.
Let's talk about psychedelics. Here's a video of someone jumping out a window after taking a hit of salvia: https://www.youtube.com/watch?v=_v26zC-1eCo
People have near-religious experiences after taking LSD, and they'll espouse the wonders of psychedelics while downplaying the risks. But there are risks.
Before taking LSD, ask yourself: Are you sure you want to be a different person afterwards? People everywhere talk about the transformative nature of LSD, so that's what you'll be doing: transforming into a different person. Exploring land is fun because you get to go places you've never seen before. Exploring how chemicals affect your brain is fun if becoming a different person is fun. So don't do it unless you're sure you dislike yourself.
People have often credited significant breakthroughs to taking LSD, but your chances of getting rich from bitcoin are significantly higher than making a huge impact on the world by consuming LSD. It'll certainly have a huge impact on your personal life, though, for better or worse.
