Recall that commercial of the Egg being dropped in a skillet. " Here is your Brain on Drugs" Well you are cooking it! This Doctor wrote a book based on the same scanning of the brain of those in Love. I saw him on PBS. The brain creates these receptors that form and give us the desires we have. Releasing a chemical simular to cocaine, and morphine and these our natural body chemistry create. The release of this natural chemical makes us feel good about loving someone, getting along, liking chocolate, wanting someone in particular. Wanting a drink of alcohol and that next drug fix. When you are away or get over someone you love. These brain receptors eventually go dormant. They do not ever disappear. They remain regardless of what addiction or desire created them. When you see that special person all these feeling rush in because the receptors turned back on, you drank that drink they turn on. So a alcoholic is never cured and can relapse at anytime, snorting that coke, one hit of herion and you back... So the video below shows our brain on drugs. On the PBS special I saw by this doctor. The brain lights up when we eat chocolate, are in love etc. Alcohol and drugs have the Black community gripped very bad. Our young children and many grown ups do not understand that this alcohol and drug use is eatting away their brain. Drinking to relax is Ok, but to excape is self medicating and causing more problems for individuals. Doing drugs is making many mentally challenged, keeping them behind and eventually cause medical isues, stroke or death.
