So your objection to any discussion of illegal drugs is exactly that - that they are considered illegal?
I'm extremely reticent to comment in threads like these because unlike the current zeitgheist or social norm I dont use drugs, other than a select set of prescription drugs and I'm not over the moon about that, I've never used drugs, I dont consider caffine or alcohol to be drugs and most people who I know who are actual drug users, whether they are dependent addicts or dabblers, would not consider them be drugs either and laugh at the constant liberal media or adolescent referencing of those habits to rationalise other ones.
I think the point has entirely been lost that the substances being discussed ARE illegal, usually not for no reason, and I see no reason why the discussions about purity vs. adulteration, supply chains, crimes and consequences can be set to one side as a sort of singular externality which would not exist where all substances legalised for sale by mega big pharma corporations (which is what the inevitable outcome of legalisation would be, Weeds did this well in an imaginary, fictional universe, although the experiences of so called legitimate businesses such as medicine man in the US in states were decriminalisation has taken place have been the same, those enterprises, which are not hoods, pushers and neighbourhood dealers, are only building businesses for sale to big pharma or big tobacco and alcohol).
Anyway, I know most drug users are not going to care whether they get their substances from a people trafficker or McDonalds, the whole legalisation debate is about will police, social services, addiction clinics, counsellors, parents, concerned family members or anyone and everyone else let them alone to experience their preferred altered state, a not too deep thinking hedonism which sees no negative consequences, or none that cant be minimised and rationalised away so that point itself is even moot, no personal health consequences, no societal consequences, no intergenerational consequences.
The illegality of these substances is largely tied to these denied consequences, that's a reality, there are principles of harm and significant harm that any properly constituted legal, societal authority can not ignore, that long wants public order and the rule of law to continue. Now you can say that you just dont care about that, which is grand, there's going to be plenty of people who do say that, or something after the fashion of that, or perhaps dont say that but whose behaviour tells a very different story from what they say, but that remains the case whether you want to accept it or not.
