It’s more likely to be down to incompetence. I can’t imagine the party UV lights are more expensive than the fuck-you-up UV lights.
EDIT: Someone else mentioned these might’ve been used during COVID for sanitation, and are extremely cheap leftover wares now that the pandemic is “over”, which would actually make them a lot cheaper.
Spoken like a true 20 year old who has no concept of what health at 75 looks like. The alcohol hangovers will last multiple days, you might have a lung condition that prevents you from smoking, your circulation will massively shit the bed off stimulants (think racing heart, cold sweats, feeling weak, anxiety) and opioids… well, opioids might be mostly okay except for the constipation I guess. Withdrawals might incapacitate you for months though.
