Squirrel that just sounds irresponsible to me. What if someone had had an adverse reaction
And needed emergency hospital treatment?
You wouldn't have known what they were on. Very smart. Jus sayin be more careful in future please.
And that's to everyone reading this.
It very much so sounds like it could be irresponsible, however I'd hope that anyone trying this, especially with the ability/drive to order RC's, would have everyone participating to be informed participants, as well as have had previous experience with every compound in question. I could see the dose levels being all over the place in terms of individual's personal needs, especially with more potent RCs whose ranges exist below 30mg. Mg's can make a difference. Also, with a group of people over 2, I'd be a bit worried about potential set and setting issues, especially with people potentially dosing drugs they are not familiar with.
Anyway, probably not a wise activity like Sega points out.
On to topic at hand/harm reduction refresher
It can be a bit frustrating (difference in durations), but with the right individual/individuals it really doesn't matter. I can not say this enough though, it really depends on those you are dosing with. After 7-8 years of psychedelics, I still hold to me dearly that there really only are a handful of people that I'm friends with that I'd considering taking more than a light ++ with, even then, I'm not completely sure. Set and setting are the most important things to taken in account before starting your journey and through out the experience from the moment you dose. So, if you feel like yourself or a friend taking that extra 4-6 hour ride on top of the shroom duration, would be awkward or whatever the fuck, I recommend against it. I certainly wouldn't trip with most people in general, but I would stay farther away from tripping with those who you aren't sure you want to be hanging out with for 12 hours with no means of getting away. Also, I wouldn't want to be done tripping after a mushroom trip and feel the need to abandon my fellow tripper/trippers who I may or may not have promised to stay for the full length of an acid trip. Having someone around who doesn't completely give off the vibe of wanting to be there, or having yourself not want to be there during an experience can be very stressful and potentially can lead to a difficult experience. Psychedelics makes even seemingly small things can feel awkward, un-enjoyable, or worse.
So, in sum of some harm reduction (yay!), take in account all the factors. Who are you tripping with and what type of relationship do you have with this person? Where are you going to be? What activities might come up (are they things you might not enjoy to be around, or take part in)? What genre, bands, or whatever, do those around you enjoy listening to while tripping, and is it what you like? Will there be any uninvited guests, etc.? (i know this possibly is very redundant, but even the best of us don't fully take in account all the factors from experience to experience, even in situations where something new is being introduced in comparison to the norm)
