You are taking risks taking this drug. Please go to wikipedia and read all about Mephedrone. Why do you think it's called bath salts? Because it's not for human consumption. Many countries in Europe have banned it. And it's not a decongestant anyway, which is what your husband needs. Buy some different OTC ones like Nyquil and all the million others instead. Give him lots of liquids and rest and have him keep his head elevated.

Your question is most unclear. Nonetheless, please contact your local Poison Control Center. They can provide an immediate response to your question and advise to needed antidote. Do not delay:
