1. Dear Drugs-Forum readers: We are a small non-profit that runs one of the most read drug information & addiction help websites in the world. We serve over 4 million readers per month, and have costs like all popular websites: servers, hosting, licenses and software. To protect our independence we do not run ads. We take no government funds. We run on donations which average $25. If everyone reading this would donate $5 then this fund raiser would be done in an hour. If Drugs-Forum is useful to you, take one minute to keep it online another year by donating whatever you can today. Donations are currently not sufficient to pay our bills and keep the site up. Your help is most welcome. Thank you.

    Dextromethorphan (DXM) is a common component of combination cold medications that has become a popular drug of abuse for young adults. Abusers of DXM have developed a simple acid-base extraction technique to “free-base,” or extract, the DXM from the unwanted guaifenesin, coloring agents, sweeteners, and alcohol that are typically included in combination cold preparations. We report a case of DXM overdose after ingestion of this purified “Crystal Dex” and discuss the “Agent Lemon” and single-phase extraction techniques that are used to free-base the dextromethorphan.
