Contrary to what the name and form factor might suggest, the Aladdin Vaporiser was not a tool to help you get high. Instead, according to one enthusiast of all things Aladdin, the device was used to make insects vanish.
Aladdin Magic Vaporiser, kills insects, with original instructions found by Bill & Treva Courter. Made by M & M Mfg. Co., Amarillo, Texas. No date. "Use the vapour method to control many annoying insects, such as flies, mosquitoes, gnats and other small flying insects." One capsule treats 1000 cubic feet.
I shudder to think what sort of gas was used in this thing, and whether or not people sat in the room while the vaporiser was at work, but if you want to own a bizarre piece of the past, the Aladdin Magic Vaporiser can be yours on Etsy for $US22. [Etsy, Aladdin Knights]
