Why does the FDA have the authority to do this ? They'd save more lives by removing all Mc Donald's from the market. Same thing with the DEA telling me what substances I can consume. Now instead of having a legal option, your encouraging underground, unregulated options. How about this, slap a big label on everything from fattening foods to recreational drugs, with " This will fucking kill you, here for a good time not a long time". Then either raise the enlistment age to 21 or drop the age of consumption to 18. It's pretty fucking absurd you can enlist at 18 ,but can't consume recreational substances until 21.
