Answer :
Peer pressure can have a negative impact on the mind because it often forces people to do things they're not comfortable with, thus exacerbating interpersonal conflict.
The pressure in social groups is something that is always present when people are grouped. The negative impact that this pressure develops translates into the influence that people exercise on us, our lives and our decisions (Personal, social work, among others). That is why in some cases this pressure is so negative on people that they totally change their way of being and facing their lives.
