It is important to know the signs and symptoms of Xanax abuse to know when help is needed for you or your loved one. Some or all of these symptoms of addiction will appear in anyone who abuses Xanax, whether they snort it, take it orally, or combine it with other drugs like alcohol. Alcohol, or other substances, can exacerbate some of these symptoms as well. It’s important to not mix Xanax with any other substances, as it can result in many dangerous outcomes.
