Can your character change from often using cocaine?
Cocaine use can change your character. Cocaine users can develop a number of negative traits during the period of heavy use. You often see that people become self-centered, cold and arrogant. Fortunately, these character traits can disappear after stopping use.
If you suspect that someone is using cocaine for a long time and you observe this change in character traits, it may be advisable to have an open conversation about this and possibly seek appropriate help (together).
