Anywhere there is a persistent problem with homemade drugs (meth), you will have issues with purchases of the ingredients or materials to cook them. Bulk purchases of cough medicines and decongestants, charcoal, propane in disposable containers, batteries and the other components got the stink eye, locally, but that has subsided a bit since the Chinese and Mexicans have taken over production and distribution, greatly aided by a nonexistent southern border. I suspect the fentanyl epidemic is impacting the meth epidemic by taking its victims right straight to Hell, instead of leaving empty shells of human beings, that require long term medical and psychological assistance the rest of their lives.
Fentanyl is killing more people in the course of a year than any other imaginary problem this administration can dream up.

Best,
