Well that was kind of an unwarranted response, don't you think?
All I was saying was you were pointing out that smoking a breakthrough dose in a car wouldn't be a pleasant experience, and I agree with you on that, but the OP didn't specifically say a breakthrough dose, and I thought that was worth pointing out. Not all of your argument is relevant to a discussion of a sub-breakthrough dose smoked in a moving vehicle.
No need to be so hostile :surprised
