Murple and PuristLove missed the point, though I'm sure they have good intentions.
Freedom isn't a special priveledge that the government gives you, that you have to work hard to keep. Freedom is what you have by default. The ability of the government to govern IS a special priveledge that they have to work hard to keep. That's not my idealized political view; that's reality. Deny it all you want, it's not going to change, ever.
If I want to take some drug, I will. Why am I not afraid to admit this? Because there's nothing wrong with it. It's my decision, not the DEA's. If they want to prove otherwise, they can expend an extreme amount of resources, and still fail to stop me, because it's impossible. The more energy they use to attempt this, the faster they kill themselves.
I do whatever I want, and I let other people do whatever they want. If you always try to limit my choices in a certain situation, whose choices are you really limiting? Your own. The joke is on you.
The only person who can take away your ability to eat a research chemical is you.
What's that? But all these federal laws say otherwise? That's nice. The people who agree to them can follow them as much as they want.
