A new study has been taken out to see the effect of cocaine on cannabinoid receptor 1, which is responsible for delaying the communication between different nerve cells. The study is said to be one of its kind, as it is first time that effect of the molecule is being studied.

The study, which has been taken out by a group of US researchers, was of the view that they have been able to find out the reason as to what makes cocaine addicts suffer from withdrawal symptoms. In order to know the same, the study researchers assessed genetically engineered mice.

They decided to focus on a single molecule known as cannabinoid receptor 1, which is also known as CB1. While studying the molecule, the study researchers came across nucleus accumbens, a part of the brain, which regulates two prime factors emotion and motivation.

Lead author Bradley Winters said that emotion and motivation level speeds up when a person is high on cocaine. Moreover, cannabinoid receptor 1 is also produced in excess when person has taken high amount of cocaine. "It is kind of like going down a steep hill so you have to start riding that brake really hard", affirmed Bradley.
