I would like to add alil more on my take on n2o, its nice but nothing you can take back with you, I dont kno about anyone else but I search for the fish out when I take it, as Is aid I have access to almost an unlimited supply of hospital grade (becauses its delived to hospitals!!) in numberous size tanks. And if I dont fish out all I experience is something similer to just a small hit of duster, just wham wham wham hwam wham and slight white out of my vision, but while I fish out I come to these HUGE apiphanies in which I see first hand solutions to the mundain problems one can create in there lives, but after about 15seconds of the sentance its always the same "wtf was I just atlking about?" also as Iv mentioned befor, I bang my shit up alot, I still have a green/yellow bruse on my cheek bone from that spill into the garbage while high on LSD (I was fucking HIGH on lsd, not realy tripping because I was mainly just getting fucked up). guh, I felt so brain dead thenext morning after killing an entire tank with a friend.... but hey, thats what happends when you search for the fish out.
BTW we hardly use ballons, besides freezing you lungs/mouth what could be a danger in this, we also dont use the mask, as we dont ahve a regulator for the tanks, just put your lips up to the tank and breeth in with mouth and out with the nose 5-6 times then hold that last one in as you hit the floor... oh mna I want a nitrous hit now!!
Also anyone ever notice that n2o is like a empty DMT trip?
