I have a good friend who tried mushrooms for the first time. He went completely psychotic. We had to call police/emt to subdue him. Ended up tied down to a gurney until he sobered up in the hospital for a couple hours.
Psychedelic are NOT for everyone. It is dangerous to suggest they are.
One time this 'guru' told me, "That is what happens when you try to put a 6 cylinder drug into a 4 cylinder mind." when referring to someone at a festival who lost their shit.
Granted it could have been a bad dose, but when everyone else around them was fine, it typically is the user who was not ready for the experience or had some underlying issues they were not dealing with, and when you take these types of drugs you don't have a choice but to deal with it.
Sadly the police/emt way of dealing with it probably caused more trauma than anything but I understand their reasoning in doing what they did.
When someone is trying these types of substances for the first time it is a good idea to make sure they are in a good frame of mind, have a few people guiding them on their journey.
If you decide to randomly take mushrooms for the first time in an environment where not everyone is on the same level as you and you have no one to guide you through your journey, you are going to have a bad time.
I like that 'guru' quote. When it comes to the trip. I always hear about the 'have a sober friend, or a trip buddy, etc' I've never thought this was the best idea. I think it could be worse for someone in a bad state to have to deal with other people.
Let a person be by themselves. Chances are they will just sit there and go through the corridors of their mind. There may be sheer terror, and at some point there will hopefully (likely) be peace and euphoria. If nothing else it will wear off in a handful of hours and if they were just sitting by themselves then they can hopefully shake it off and get on with things. I think it's dealing with other people that could raise the situation to unstable levels.
