    Don’t work when you smoke weed.

    I rarely smoke it (haven’t in at least 4 years), but when I do and sex happens, I can’t breathe and I end up totally stopped up for at least an hour.

    I have allergies too though.

      Orgasms, exercise and other “arousal” stimuli like fear or aggression make your blood vessels shrink (vasoconstriction). From the link I posted above: “During arousal, your sympathetic nervous system — the one that activates your fight-or-flight response — kicks in. Just as when you exercise, your adrenaline levels go up and your blood vessels constrict. Less blood flow to your nose means less inflammation, so your nose opens up and you can breathe more easily.”

      THC can cause vasodilatation, which is the opposite (blood vessels expand) so it makes sense they’d reduce effects or cancel each other out. Fun fact from the same article, it’s also what causes the bloodshot eyes associated using weed.
