You know your rights. You have had friends who got picked up on drug charges, after all, and you started doing your research. When the police approach you, you are not intimidated. You know what they can and cannot do.
This is very good, but the reality is that police officers often do not expect you to know your rights, and they may even get angry when you do.
For example, the police told one man that he had to get out of his car when they had no legal basis to do so. He told them he did not have to get out. In response, they opened the door and physically dragged him from the car. They arrested him and said he "resisted a search." It was a clear breach of his rights, though, and they ultimately had to drop the charges.
In a similar case, a woman got pulled over and decided to use her right to remain silent so that she didn't have to talk to the officers. The police officers began screaming at her and, like the man above, they dragged her out of the vehicle. They also had to eventually drop the charges against her, though she did spend time in jail for doing nothing more than simply standing up for her rights.
It's important to keep cases like this in mind during a drug arrest. If the police violate your rights and break the law, it may mean that drugs and other evidence they find are not admissible in court. It is critical for you to understand not only your rights but also the legal defense options you may have.
