Sigh...
People need to understand that a trip is a result of three factors: substance, set, and setting.
Ripping flat TVs off the walls and fighting cops has little to do with the substance- that happens ALL THE TIME with alcohol- but likely much more to do with the set and even more so with the setting.
Mushroom can provide overwhelming, animalistically spiritual experiences and it's never made sense to me why people take them at parties. Taking them somewhere with other people consuming alcohol or accelerants or where the vibe is uncontrolled and hectic is likely to be a bad time, but that has little to do with the mushrooms and more to do with the setting. The setting- whom you're with, what's going on between the people you're with, what you're doing- is crucial to determining the trip. Where you're at- the set- plays a huge role, as well. If you're chilling at home or a friend's house, you'll probably feel comfortable, whereas if you're out at a bar or a club, you could become disoriented, frightened, etc.
Eating a bunch of mushrooms is going to get you really high on mushrooms, nothing else at all. What you choose to do from there will largely be influenced by where you are, what's going on, and whom you're with. Eat a bunch of good mushrooms, choose good friends, and find a good, chill place to hang out. But most important, eat a bunch of good mushrooms. A bunch.
