Cocaine Withdrawal Side Effects:

Chronic pain in the chest and coughing sometimes accompanied by severe chest pains are common reports of withdrawal patients.

Phlegm coughed out is black in color and does not have blood in it unless the patient has other respiratory problems. This coughing can be treated by over the counter cough syrups or large dose of water intake and other juices.

Violent cases of withdrawal associate muscle spasm. Minor spasms are minor indication of worsening problem in cocaine addicts since people who develop them tend to suffer more physically violent symptoms of drug withdrawal.

Panic attacks are not uncommon to recovering users and addicts.
