I do not see a reason why pharma and chemical engineers cannot open a drug store. Certifications, licenses and permits are dependent on the laws governing your location. Each state has a board which evaluates pharmacies and grants licenses. You should contact your state pharmacy board for a permit or a license to open a pharmacy store. If you find the laws complex, you should consult a lawyer who is savvy with the laws of the locality where you would like to open a medical shop, and also use them for the necessary paperwork.
