What is Dextromethorphan ?

First of all, what is DXM, or Dextromethorphan? DXM is a cough suppressant chemically similar to morphine found in most over the counter cold medicines. DXM is usually taken in large doses very quickly. Users must take the substance containing DXM quickly because soon after taking, they will throw up. Drinking it quickly will get the medicine working in the body before it leaves the way it came in. Now there are DXM powders so vomiting doesn't occur. DXM can be taken as a liquid, powder or pill.
