If they don't have venom, then they're not venomous snakes. If the question is why some snakes don't inject venom on particular bites despite being members of a venomous species... Some species can choose to release venom or not release venom. They may not inject venom on a "warning bite" and instead reserve it for hunting. Other species always inject venom ... if they have any. But they may have recently bitten something else and used up the venom supply, and the glands that produce it haven't had time to "recharge" the supply yet.
