This question is very complicated, and the answer depends mostly on where you are located and the sort of chemistry you are conducting. For instance,
if you reside in Texas almost any form of amateur chemistry can be considered intent manufacturing illicit drugs.
Many people have had their labs raided, which you can read about the in the Legal and Societal Issues sub forum.
Things which will decrease you chances of being raided include keeping a lab notebook, maintaining a clean lab where everything is labeled, being
knowledgeable about both chemistry and the law, and being friendly with your neighbors. |
