Say a mosquito bites a smoker just after they smoke a cigarette. Since there is nicotine running through the bloodstream, you'd think they could potentially get addicted right?
Not likely. Mosquito brains don't have the pleasure centers that more developed brains in higher species do. Most mammals can become addicted to nicotine. I've known farm animals to acquire a taste for tobacco and will eat it whenever they get a chance, and go through apparent withdrawal symptoms when it's taken away from them.
If insect bodies were tiny replicas of human bodies, yes. I don't think there's actually any way of knowing without conducting lab tests. Sounds like a science project to me
