What is what does it mean to hotbox a car?

Hotboxing a car refers to the act of smoking cannabis (or sometimes other substances) in a vehicle with all the windows closed to maximize the concentration of smoke. The goal is to create a thick cloud of smoke within the enclosed space, theoretically intensifying the effects due to increased inhalation of the active compounds and secondhand exposure. It's important to understand the potential legal consequences of possessing and using cannabis, which vary significantly depending on location. Additionally, health risks are associated with inhaling secondhand smoke, and the practice can leave a noticeable odor in the car, making it difficult to conceal.
