Beat me to it. Now, almost all snakes other than constrictors are technically classed as “venomous,” since they have something they use on their prey. Though not significant at all to humans, let alone medically significant, little garter snakes still have venom. But before they can even think of using their back teeth on you, even the feisty ones seem to get their front teeth stick in your outer layer of skin, so not even allergy worries, really.
Since you seem to be a savvy herper, have you heard anything about the new copperhead venom research into why there have recently been more deaths to healthy, full-grown people due to a venom allergy than before, just over the last 5 years or so? The anti-venin actually hastened one death I know of. Researchers are looking into whether their venom is evolving to be more than what used to be classed when I was a kid as “semi”-venomous, though medically significant. I leave them alone, unless I need to move them, but the possibility of a bite concerns me a little more than it did before the recent spate of allergy deaths, and the little guys are everywhere in rural Tennessee.
