For the record, since I still consistently see most people confused about this:
CBD will not get you the slightest bit 'high'. In fact CBD has actually been proven to make you
less high. Some folks claim CBD reduces the symptoms of ailments like anxiety & chronic pain (though it's never worked for me in those areas fwiw), but I doubt that's what they're suggesting at the gas station boner pill & organic speed display. There are plenty of unscrupulous brands & vendors out there trying to take people's money by murkily implying that CBD will get you intoxicated or buzzed in some manner. It won't.
