Depends on the cart, man. You can get some cheap-ass disposable 510 carts for nicotine that don’t look THAT different from the 510 weed carts. The atomizers are completely different, as is the wick, but the average person scanning doesn’t know that.
And as you get into disposable weed vapes they’re not dissimilar from the disposable nicotine ones. Again, different tech for actually vaping, since oils and PG/VG behave differently, but the average person won’t notice.
