Is the individual not responsible for knowing his mental state, physical health, other medications? Is he not capable of making an informed decision without VERBAL interaction with a Doc? What if the warning (assume it's warning literature and not a label) were written by a doctor specializing in patient education about hazardous substances? Edit: I'm trying to keep my posts short (and most likely sacrificing some clarity) because I'm posting via phone.The difference is that the doctor is responsible for knowing things about you and your mental state, your physical health, the other medications you may be on, the purpose of your desire for the medication or the general need for it, the risk of the medication itself alone and in conjunction with all the other conditions stated above, weighing that risk, making a judgement on the appropriateness and safety as well as efficacy of the substance, then also counseling you on all these things so you can make an informed judgement together and then prescribing the medication under recommended guidelines, monitoring its use and effectiveness, along with any potential side effects, even those unnoticed by the user, adjusting dosage appropriately given all the ongoing and changing circumstances and health conditions and making sure it is being used appropriately, safely and is not being diverted, abused or having delterious consequences otherwise not considered. So... no... a warning label is not sufficient. <edit> Whew... now my fingers hurt.
Further edit: what if average joe consulted with a team of doctors and still decided he wanted to buy meth that was produced at a well regulated facility?
