Couple thoughts as an Oregonian where 3 significant drug related legal changes have occurred:
A) Pseudophed is no longer available OTC
B) Weed is legal
C) Small amounts of Meth, Cocaine, and Heroin have been decriminalized
Regarding A - the backyard meth brewer is gone. It has been supplanted by Mexican cartel meth, which carries its own (bigger) bag of shit. If you're a non scumbag, and you have a runny nose - you need to pay $, schedule time off and go to the Doc for something that you used to be able to pick up at the market. Same meth addicts, same property crimes.
Regarding B - I can not tell you the litany of issues here. It gets sold to the youth vote and the libertarian / left leaning voter block as 'freedom' - it is anything but. From a John Q public perspective, understand there is a very high percentage of persons that are driving stoned (don't bullshit me with stats on crashes, I'm living it); from an employer standpoint, your applicant pool pisses hot, you have issues getting INS b/c of it, there is an increase in sick days b/c smoking dope exacerbates the symptoms of a cold / flu, then there is the lost productivity from those that perseverate (even when they are not 'high'). From a Marijuana business standpoint (those who produce / process / retail) the laws and associated compliance regs are copious to say the least. Having looked at it seriously from a client perspective, I can tell you without a doubt that you are staring civil asset forfeiture (Real Property) in the face; all the while the State is telling you they aren't going to bat for you against the Feds, the Feds are telling you it is illegal, and everyone in the industry is hanging their hat on the 3 Cole Memos (think of it like a non binding opinion letter from the ATF on a firearms matter - subject to change at the discretion of the director). Let me be exceptionally clear here on this point - the only reason it is 'profitable' is b/c it is leaving the state. I can not emphasize that enough.
Regarding C - this is new and the full effects remain to be seen, however at this point I do not see an upside.
The short version is - none of the above 'fixes' any problem for any of the individuals that use drugs, or those that care about them, or those that depend on them for care. Furthermore, for the rest of us it creates additional problems, higher costs of doing business, and lost productivity.
Regarding the 'Libertarian' viewpoint on drugs - it is a false construct to begin with. Unless we remove all societal protections and benefits from those that choose to do drugs such that every action and every consequence is 100% on them, their actions will always impact others.
Regarding wholesale change to drug laws, that is a non starter once folks get their head around the GDP number associated w/ enforcement.
*I* would sterilize that woman.
