I think a better analogy would be crack pipes sold in minimarts in a box that says "for tobacco use only". Crackheads estate sues the pipe mfr says you knew people were using it for crack and are proximately liable for facilitating the drug use.
..and any delivery, distributors, importers, and shippers should be held liable, also.
I watched a drug addict lovingly turn a plain lightbulb into a meth pipe.
