I think there's some confusion over terminology - the whipped cream dispensers are these things:
which you screw the little 8g canisters/cartridges or 'whippet's into. No need for crackers or balloons
As for safety, for a light user you're probably OK, however I no longer think N20 is as 'relatively safe' as I had previously believed. The stories about both neurological damage and potential lung/breathing problems I think are real, and are obviously long term/potentially permanent health issues, although there are apparently ways to minimise those risks. No drug is risk-free of course
Whilst i do agree no drug is risk free i think people drastically underestimate just how damaging these can be.
i did significantly more damage using nitrous in a few months than i did with years of pretty much everything else.
Much like drunken recall, someone else mentioned in this thread something about accessing memories made whilst on nitrous.
I stumbled across some seriously fucked up childhood memories of being dosed by abusive adults along and then went through thousands of cannisters in a short period in an attempt to clarify these memories.
I developed a taste for this stuff before i hit double digits in age then forgot it existed for a decade or two before recalling numerous repressed memories linked to using no2
off i went continously diving back in hoping to get some clarity on these memories and binged them for months straight
In the process i managed to almost lobotomize myself, particularly around the front left hemisphere. I literally felt neurons burn out to the point that i was unable to produce any seretonin or dopamine for a significant period afterwards..
the wires got crossed so much that laughter actually caused me physical pain in my head.
it's possible i caused a minor aneurysm, or several, as well as what was likely a seizure, jaw locked muscles tensed and i could not move or open my eyes for a period of time during which my brain felt like an electrical storm
At one point i could feel what seemed like bleeding across my frontal lobe. I felt neurotransmitters explode and melt on the inside of my skull
paty of my respitory system collapsed, almost like what happens to deep divers who ascend too quickly
brain zaps for months afterwards
the inside corner of my eyes where the eyeballs absorb oxygen also collapsed.
There were stages that my body and subconscious were basically trying to warn me just how much damage i was doing
at one point the audio distortion flange type hallucination ceased and another auditory hallucination (or bring depending on your spiritual view) said "if you take this next hit you wont be able to smoke weed anymore"
being a daily smoker at the time i didnt heed the warning, which turned out to be correct. Any time i smoked after that caused pain in my frontal lobe where i must have burnt out some receptors.
Despite all this i persisted in attempting to clarify the memories though in the long run i may well have distorted them further.
i felt veins collapse and parts of my central nervous system burn out
One lung may have collapsed or i put a hole in it
for anyone familiar with dmt beings etc, i felt like doing this left my physical body open to attack from much lower level beings than those i had ever encountered previously on psychedellics.
In the space of a few months i lost a relationship, an apartment and quit my job all while chasing these memories.
To this day i still have doubts regarding just how much of all this was even solely my idea, losts of paranoia at the time regarding mk ultra and various other mind control experiments.
The building i was living in had air tight foor seals on the fron door of every flat but mine, the oven had a gas leak and for a few months the apartment was just full of NO2.
Moral of the story is i dont think these can be done safely, and i am sure they have been used in human experimentation around building false memories, splitting personalities and creating alters ala mk ultra and project monarch or whatever variation continues to this day.
Stumbling around outside one day during this time a strange lady opened her hand and blew a cloud of something in my face as we crossed paths, i was convinced it was scopolamine and that it was an attempt to increase my suggestibility at the time.
I used to love weed so much and they ruined that for me, along with everything else i mentioned.
Feels like i shrunk my vocabulary by a massive amount as well as my ability to properly articulate myself
i have trouble thinking conceptually and making any sort of plan these days
there is more to the story but the point of this post was meant to be these are much more dangerous than numerous other illicit substances, both to the physical self and any kind of psychedillic learning
TL;DR
stay the fuck away from nitrous oxide imo
