But for that kind of thing it would seem to be much easier and probably cheaper just to mail order the drug from overseas, or even book an inexpensive flight and buy some. For example, bromhexine and ambroxol are cold remedies that many people find effective, are not available in the US, but are easy to mail order from any number of Japanese sellers. The difficulty of hiring a lab or setting one up yourself would seem to be worthwhile only for new or unusual medicines that could not be obtained this way.
