How drug works against cell communication
Nicotine is shaped like acetylcholine, so it attaches to the acetylcholine receptors and mimics the neurotransmitter. Acetylcholine is responsible for muscle movements, breathing, memory, and heart rate. Nicotine can also acts as Dopamine, which controls pleasure. This is the same neurotransmitter that heroin and cocaine imitate.
