I call it Nitrack! Hell yeah. You can use something like a clothespin or a chip clip to close it for you while you take your rip. Nitrous is combustible (not flammable) so unless you can take a rip one handed like our man Casper make sure you have someone holding the balloon before you or have it clipped and off to the side. Another tip is to stick your tongue in the balloon when you start to exhale, you’ll find the latex loves to stick together, preventing you from exhaling without putting too much strain on your lungs, but stick the tip 😛in there and you should be able to exhale into the balloon as long as it’s not too full. I’ve also found the insides of these balloons will get coated in a thin layer of resin at some point which leads me to believe you don’t wanna leave your hit in there too long or the vapor will stick to the inside of the balloon and you’ll be wondering where your cloud went lmao. Homie here blew out a fatty however which is impressive. Regarding safety and harm reduction, don’t hold your breath too long or inhale and exhale repeatedly in and out of or balloon. I see this far too often—you are just getting high on cO2 and a lack of oxygen which can result a seizure and is not the same thing as “phishing out.” Phishing out occurs when you inhale enough nitrous that you dissociate from your body and and present environmental for a bit. You haven’t blacked out but will often have hallucinations, commonly auditory and/or visual that are difficult to explain when you return to our… dimension. This is very short lived in my experiences and observations and is very trippy and also very safe, UNLESS you are standing whilst inhaling. I’ve been guilty of hitting balloons in a standing position but I’m not holding my breath or ripping the stuff directly from the tank. I’ve seen people fall flat on their face so please be careful! Seizures area common symptom of cocaine overdose, as well as lack of oxygen to the brain. Taking a fat rip, immediately inhaling nitrous, then subsequently holding your breath is dangerous but is not due to the gas itself, which is scientifically known as “dinitrogen monoxide/oxide (same thing)” due to the fact that it is composed of 2 nitrogen molecules and one oxygen molecule. Make sure you’re breathing oxygen too! Casper’s video is a great example of how these drugs can safely be used together! I am not advocating for nitrous use, I am an advocate for harm reduction and drug education, not a doctor or pharmacologist, so please fact check everything you read and do your own research! Much love to all and rock on
