HI, thanks for using healthcare magic At the moment, like traditional antidepressants, there is no known risk of addiction to the kalms. It is quite possible that the use of this supplement (kalms), may help to reduce your anxiety. As with all medications there is a risk of side effects, so far nausea, stomach cramps and increased heart rate have been reported. These effects do not affect everyone and you may not experience these effects or any problems with the medication. If you do have an issue, it should be reported to your doctor or pharmacist. It is important to remember as well, that the commonly used anti anxiety medications are not addictive eg cymbalta, zoloft, celexa, paxil etc They are also only used for as long as a person needs it. I hope this helps
