Cocaine addiction

With cocaine, becoming psychologically addicted is more the issue than physical addiction.  Cocaine's effect is very seductive because the high produces strong elation and illusions of power.  Because the high is so short lived, the user tends to need to use often in order to sustain those feelings.  And resistance can build very quickly with one needing more and more to reach the initial high.  If you have been using for 2 weeks and it makes you feel "unbelievable" and already you are using throughout the day and need more and more, it is best to stop as soon as possible.  The escalation you describe suggests that there is likely some degree of self-medicating that is motivating your cocaine use.  Although physical addiction is secondary, physical side effects of cocaine is substantial irritability when the high wears off and, with long term use, a physical deterioration.  It may be useful to go to an NA (Narcotics Anonymous) meeting to experience the destruction that cocaine addiction can cause.
