Reply #14: When one does cocaine, [View All]

[Ariana Celeste]

one can have the same behavior as a very stressed person. Considering that it can make you paranoid, raises consciousness, raises awareness, increases concentration, and increases your heartrate, one often will find themselves clenching their jaws, playing with objects, twiddling thumbs, and so on. Effects vary from person to person, but jaw clenching is fairly normal for coke users.

It doesn't happen to people who were once addicted but quit. Although other forms of stress/tension do cause the same types of reaction.
