Many national brands have some kind of inspection behind them - UL listed, or FDA approved. I'm wondering what a 'brand' printed on a laser printer in somebody's garage is worth, in terms of product safety.
Yeah, that's an interesting question. But it seems weird to suggest that any non-local buying psychedelic truffles in a smartshop is "stupid" because they shouldn't trust the brand. I don't really see how it has anything to do with whether you're local or a tourist.
