Make your dentist happy! Brushing your teeth while high will ensure you’re scrubbing ‘em for the recommended 2 minutes.
When you’re high, you often get carried away with what you do. What normally takes 30 seconds will usually take about triple that time when you’ve been smoking. Take advantage of this loss of time and brush your teeth. They will be unbelievably clean, and having freshly clean teeth may prevent you from giving into the munchies.
