Can you get high off of second hand weed smoke?

Yes, to some degree, you can get slightly high and light-headed depending on the actual amount of second hand weed smoke and your proximity to it. The original smoker of the weed, the “first hander”, actually absorbs the majority of the thc and other particles via the membranes of their lungs, throat and mouth. For nicotine in cigarettes, studies have shown that up to 90% is absorbed by the original smoker during inhale/exhale.  For the thc content of second hand marijuana smoke, it is assumed to be similar.

What about when you hotbox a car or small contained area?

Yes, that is drastically increasing the likelihood of someone getting high off of second hand weed smoke. Everyone, even people not smoking weed in the hot box, is getting low oxygen and high carbon dioxide after a short while contained, and that alone will provide a lightheaded “high”  On top of that, if you add in the increased concentration in the amount of smoke, even post-absorbed and exhaled, you’ve got minimal thc content. For the irregular weed smoker, that minimal thc inhaled may be along with the lack of oxygen to “get high”
