I have smoked and eaten (accidentally, brownies) marijuana several times in younger years. Every single time I became psychotic. Frightening. Maybe it’s just my biology but pot, for me, is a dangerous drug.
We only use the betadine nasal spray (two sprays per nostril and lean head back to let excess drain) before going out and then again once home. If out for longer than 3 or 4 hours, another round of the stuff seems like a good idea.
