The FDA exists to tell you, a free individual, what you are allowed to put in your body. It has been a very long time since the FDA has been about safety only. It is wholly captured by business interests in food and drug industries. So yes, they, and the government culture as a whole, hate recreational drugs that they don't control in some way. No shooms for you but drugs that cause suicidal ideation are prescribed by the millions.
I am wary of people "looking out for your safety" when there is financial incentive to do otherwise.
