It's almost unbelievable how strong the resistance to marijuana legalization since we know that prohibition did not work when it came to alcohol in the 20th century. It has been proven that legalization of substances takes away power from the black market, whether it be bootleggers or drug cartels. It's even more outrageous when you consider marijuana's health benefits and the fact that it's still classified as a Schedule One drug, meaning the DEA deems it as dangerous as heroin or cocaine. A big reason is the lobbying of the alcohol industry. If recreational cannabis ever became legal, the alcohol industry fear that they lose consumers who would switch to cannabis do to its less harmful effects; 27 percent of beer drinkers would substitute marijuana for alcohol if it were legal in their state, according to Forbes. Another factor is the pharmaceutical industry, as less opioids would be sold if medicinal weed became legalized at the federal level. Then there's the private prison industry and police unions, which want to continue the War on Drugs and incarcerate more non-violent drug offenders. Which do you think is the biggest obstacle facing marijuana decriminalization?
