Nothing ruins a night out like getting caught smoking a blunt by event security. Sure you could just get stoned before you get to the club, like an adult, or you can just bring the inhaler-shaped Puffit in your pocket. No one will be the wiser. But man, at what a cost.
Yeah, no, fumbling with a small wooden box and exposed electrical connections is real subtle. If you really want want to get high on the down low, you need to conceal your vaporizer as something that doesn't look like a vaporizer but also doesn't look like an IED. Something like an asthma inhaler, for instance.
