Which of the following is included in drug paraphernalia related to inhalation?

The correct answer is a vaporizer because it is specifically designed for inhaling substances, such as tobacco or marijuana. Vaporizers heat the material to a temperature that releases its active ingredients in vapor form, making it easier and often safer to inhale without producing smoke.

In contrast, the other options do not have a direct connection to the act of inhalation in the same context. An office chair, for example, serves a completely different purpose, primarily providing seating. A cooking pot is associated with food preparation rather than inhalation. Similarly, a camera lens is unrelated to the usage of any substances meant for inhalation. Therefore, the vaporizer is clearly the only item in the list that qualifies as drug paraphernalia related to inhalation.
