Learn what your talking about. Engage brain, then answer. How long have you been smoking? I can almost guareentee that i have been smoking longer, and therefore know more. The THC is absorbed almost instantly. If you breathe out naturally then the THC content of the smoke your breathing out would be so small its not worth holding in.
