:wtf:

Once I was on a smoking sabbatical and was in the back seat of this guy's car and he and his friend were taking bonghits and hotboxing the car and I got pretty blazed just from the second hand smoke. Granted it was a lighter high but lasted a while. The amount of smoke escaped from the bowl was negligible.
