That's true! Making booze legal just created a market for pot.
The cartels won't stop until they are stamped out of existence.
In the 1800s when Britian was colonizing India there was a religious sect called the Thugees (where we get the word thug from). The practice of their religion involved murder, rape and theft. The British exterminated them. No trials, no civil rights claims. They were exterminated like vermin. Now there are no more Thugees.
That's what we need to do with the Cartels. A war of extermination.
Legalizing booze didn't make the Mafia go away either, they just branched out into other rackets. The Cartels will do the same, I can't believe there are people who think that if we legalize drugs the Cartels and drug dealers will all turn into law abiding citizens overnight.
Most will not (turn into law abiding citizens). But that's another problem which might be solved if our culture was not stuck on doing the same thing over and over and expecting a different result.
Organized crime is a product of prohibition. Gambling, drugs, prostitution are less profitable, safer and easier to control if licensed and regulated by the state. To bring the enormous amount of dollars spent by consumers into the market (and out of the black market) makes sense. Of course doing so with MJ threatens the bottom line of the special interests - alcohol and big pharma - and will always be opposed by them.
MJ is not a gateway drug; if there is any gateway drug it would be nicotine.
MJ can be detected by a simple urine test and an officer properly trained can testify as an expert witness that a person arrested for DUI was under the influence of MJ at the time s/he was cited.
MJ is a schedule I drug; if the DOJ removed MJ from schedule I and treated it as it does alcohol (i.e. allowing each state to determine its status) substantial revenue would be collected and might be used to treat addictions (to alcohol, tobacco and other dangerous drugs). As it stands today, the revenue from the sale of MJ and other illegal drugs goes into the black market and is used by organized crime to engage in other antisocial activities.
