Ease of use
Even though pushing a button on a USB-rechargeable vaporizer seems infinitely easier than loading a bowl or rolling a joint, these devices can come with their own unique hassles. Especially in the case of flower vaporizers, the process of loading the tiny chamber can be a headache, as can cleaning out the vaporized plant material when you’re done -- something that seems to take only a couple puffs on many units. Also, a portable vaporizer will eventually run out of battery and have to be recharged, possibly leaving you not-so-high and dry if you forget to plug it in and don’t have a USB port available.
Sure, lighting things on fire can seem primitive at times, but it’s still a reliable and easy way to consume cannabis. If you have a small pipe or rolling papers and a lighter or matches, you can smoke in practically any condition. Plus, smoking basically gives you the same experience every time, whereas a vaporizer with a weak battery may give you a wispy, worthless hit that’ll just waste your weed.
