How to become a permanent resident?
A permanent resident is someone who has been granted authorization to live and work in the United States on a permanent basis. As proof of that status, a person is granted a permanent resident card, commonly called a “green card.”
You can become a permanent resident several different ways, such as being sponsored by a family member or employer in the United States. The steps to getting a green card vary depending on which category you fall under.

Over 90 percent of adult cocaine users between the ages of 18 and 34 report that they smoked cigarettes before using cocaine. This led scientists to wonder if nicotine changes our brains by making them more sensitive to cocaine and other illicit drugs.
A recent study in mice showed that nicotine had an effect on certain genes in the brain that could make them more susceptible to cocaine addiction.
When exposed to nicotine those genes worked harder, making it easier for the brain to become addicted to cocaine. The effect only happened to mice brains exposed to nicotine before cocaine, and not the other way around. The research suggests that reducing smoking in young people may help reduce the risk of later cocaine abuse and addiction.
