10 Plants That Want to Straight Up Kill You (And Can)

You’d be surprised at just how many poisonous plants are out there. Unlike people, or the rest of the animal kingdom for that matter, plants don’t have the ability to move around and run from danger. That’s why some have developed thorns, others became spicy, and others downright deadly. Below we’ll be discussing 10 of the most deadly poisonous plants in the world.
10. Tobacco

 

Please don’t get us wrong, we’re not trying to make any anti-smoking campaigns here, but we do have to take a look at some facts about tobacco here. Firstly, all of the plant’s parts, especially its leaves, contain anabasine and nicotine alkaloids. And both of these compounds are toxic by the way. Mimicking the effects of acetylcholine, a naturally-occurring molecule in charge of stimulating muscle tissue, nicotine acts primarily on the autonomic nervous system. If eaten, the tobacco plant can be fatal. A dose of 50 mg can cause respiratory failure and general paralysis. Smaller doses of nicotine can cause heart palpitations, high blood pressure, nausea, and dizziness. One cigarette contains about 3 mg of nicotine, making up between 0.6 and 3% of dry weight of tobacco, and gives a sense of alertness and well-being. By “tickling” the pleasure receptors, nicotine is also highly addictive and causes withdrawal symptoms in smokers if they try to quit, or have run out.
