According to multiple sources, Attorney General Jeff Sessions is going to revoke the Obama-era Cole Memo, which directed federal law enforcement to respect states’ marijuana legalization laws. Once revoked, federal prosecutors in states where marijuana has been legalized will independently decide how to enforce federal marijuana policy in their states. This could create chaos in the fast-growing cannabis business which has been creating large numbers of jobs and burgeoning tax revenues for state and local governments.
It is unclear how Mr. Sessions thinks that such a move would benefit Sessions or help him carry out his job, other than repealing an Obama-era rule might get him back into the graces of President Trump.
The only other option is that Session is supposed to help address the Opioid Crisis. He thinks that cannabis has somehow contributed to the crisis ala the Gateway Theory of drugs, which assumes that cannabis smokers will turn into heroin addicts. The Gateway Theory has long been debunked for many reasons. In fact, cannabis and cannabis legalization has actually reduced the crisis somewhat. Cannabis is now being successfully used to treat opioid addiction. In states that have legalized cannabis, the number of opioid overdose deaths have actually decreased.
In any case, it will be interesting to see how people react to a new crackdown on cannabis in states that have successfully repealed federal law and enjoy very positive results.
