My question is what your standard is for deciding what dual-use technologies/products should be criminalized. I understand you believe all drugs that are currently illegal should stay illegal. What I'm trying to understand is what consistent principle you apply when you form an opinion on what dual-use items such as butane, pipes, hemp, etc. should or should not be prohibited.
"is what consistent principle you apply when you form an opinion on what dual-use items such as butane, pipes, hemp, etc. should or should not be prohibited. "My personal consistent principle? I would say, "1) According to the manner in which the product is advertised for use, and/or 2) According to the manner in which the product is actually used.
When applying the above, I take into consideration the scope (if any) of the legitimate use of the product.
Remember the McDonalds plastic coffee stirrers that had a little spoon at the end? Turns out that the spoon was exactly .1 cc, the ideal heroin dose. That met my #1, but failed #2.
