I’ve never gotten it from a dentist and thank God. I’d way rather get local anesthesia. Hydrocodone is an opiate and a pretty fucking good one. That’s for sure gonna be addictive. Nitrous oxide isn’t addictive physically and it at leadt used to be a really weird drug to be hooked on, still feels that eay ti me since the examples i csn think of are Dennis Hoppers’s character in Blue Velvet and Kanye. Its a reallt weird drug to get hooked on that ive never ever heard of people getting addicted to irl. And it’s harmless health wise, people depriving themselves of oxygen by sucking it down for too long or not having good motor control and falling down stairs or something are risk factors cause it does mess up motor control, but so does booze but aside from that risk it’s super safe. You’re basically comparing heroine and weed here except most people smoke weed which makes it less healthy than nitrous oxide generally. It does seem to have gained a level of popularity where it’s being used in doses I never did. We’d get a cracker and a few packs of whipped, fill a few balloons and pass em around but the high is closer to shit you’d maybe do in Jr high like huffing gas or dust off but cleaner and with a neat lingering high. It’s okay, but it’s not anything for a rich person to get addicted to. Do heroine instead if you have millions
