How can you tell the difference between a venomous and non-venomous snake?

What are the 3 types of snake venom?
Hemotoxicity refers to the toxicity of the venom itself, while neurotoxicity is caused by the toxic effects on the central nervous system (CNS) and/or the cardiovascular system. Snake venom has been shown to be a potent neurotoxin in vitro and in vivo.
In the present study, we have investigated the antinociceptive, anticonvulsant, anti-inflammatory and neuroprotective properties of venom from the common rattlesnake (Rattus rattus) in mice. The venom was administered intraperitoneally (i.p.) or subcutaneously (s.c.) to mice at a dose of 0.1 mg/kg body weight (b.w.).
The results showed that the injected venom significantly reduced the immobility time in the forced swim test (FST), the tail suspension test, the open field test and the elevated plus maze (EPM), as well as the locomotor activity of mice in all tests. Furthermore, it significantly attenuated the hyperalgesia induced by morphine in rats.
What happens when a non venomous snake bites you?

The pain is often accompanied by swelling and redness of the affected area. In some cases, it may be accompanied with nausea, vomiting, diarrhea, and/or abdominal cramps. : Burn, blisters, or ulcers may form within a few hours to several days after a bite. They may occur on the skin or in the mucous membranes (e.g., the mouth, nose, eyes, ears, etc.).
They are usually small and superficial, but may also be deep or deep-seated. If they are deep, they can be difficult to heal. Severe burns may require hospitalization and treatment with antiseptics, antifungals, anti-inflammatory drugs, analgesics (pain relievers), and anticoagulants (blood thinners).
What does a non poisonous snake bite look like?
