Love is as strong if not stronger than a lot of actual drugs.
The amount of endorphins released by the brain when a person is in so called "love" is tremendous. Some studies have seen similarities with people who are in love and people who are using coke.
Withdraw.... lets not go there... people become psychotic and many times even kill those who they say they love when they find out the love of their lives doesn't love them as much.
Love is scary... and beutiful lol
