VHS cleaners. “Rush.” Etc.
These are very popular in the gay community, and pretty fun. They last a very short time but give a pretty intense euphoria when paired with other activities.

First, acknowledging op is asking about amyl nitrate, something else entirely.
My experience with nitrous oxide is completely different. I used it regularly throughout my teens and twenties, easily hundreds of times in total. I never developed an appreciable tolerance or had any adverse effects, though I made sure to use it responsibly and to regularly take a B12 supplement with frequent use.
The difference in our experiences just highlights the magnitude of variability in human physiology.
Yeah sorry never heard of it until this thread. TBF, OP used slang terms. They could have just said “amyl nitrate”
