Researchers who looked at the Magnetic Resonance of the brain proved that "Intense passionate love uses the same system in the brain that gets activated when a person is addicted to drugs" says Arthur Aron a psychologist at the State University of New York at Stony Brook. Experts have said that romantic love is one of the most powerful emotions that you can have, it leads you to be happy or sometimes even anxious or even compared to an "emotional roller coaster" which comes from the pleasure center in the brain. Scientist have said love can be compared to an addiction it is not necessarily  a bad comparison to it, but as it is in a way triggers the same thing in the brain a drug would do.
